I'm trying to save a Map<String, List<MyObj>> in sharedPreferences.
I tried to use the classic sharedPreferences package, but I'm having trouble.
If I save a string to sharedPreferences, then when I try to retrieve and use json.decode(...),
I get the error Unhandled Exception: FormatException: Unexpected character (at character 2)...
If I try to save it using json.encode(...), I get the error Unhandled Exception: Converting object to an encodable object failed: Instance of 'MyObj'.
What I'm trying to save is like this:
{ExampleString: [Instance of 'MyObj', Instance of 'MyObj'...], ExampleString2: [Instance of 'MyObj', Instance of 'MyObj'...], ...}
How can I solve this?
Is there a package that allows you to save map?
You have a custom object:
class User {
String name;
String age;
String location;
User();
}
Create toJson and fromJson:
Map<String, dynamic> toJson() => {
'name': name,
'age': age,
'location': location,
};
User.fromJson(Map<String, dynamic> json)
: name = json['name'],
age = json['age'],
location = json['location'];
Then save it like this:
prefs.setString(key, json.encode(value));
Load it like this:
json.decode(prefs.getString(key));
Im having the problem above, I understand that in my data some things are null for example the leistungData from Diesel doesn't contain anything, so the title is null:
"title":"Benzin",
"leistungData":[
{
"title":"240 PS"
}
]
},
{
"title":"Diesel",
"leistungData":[
]
},
So I get that I get the 'Null' is not a subtype of type 'String'. But how can I change my code below so that I can keep this Json structure?
import 'leistungData.dart';
part 'treibstoffData.g.dart';
#JsonSerializable(explicitToJson: true)
class TreibstoffData {
final String title;
final List <LeistungData> leistungData;
TreibstoffData(this.title, this.leistungData);
factory TreibstoffData.fromJson(Map<String, dynamic> json)
=> _$TreibstoffDataFromJson(json);
Map<String, dynamic> toJson() => _$TreibstoffDataToJson(this);
}
& here the LeistungData:
import 'package:json_annotation/json_annotation.dart';
import 'unterscheidungsData.dart';
part 'leistungData.g.dart';
#JsonSerializable()
class LeistungData {
final String title;
LeistungData(this.title);
factory LeistungData.fromJson(Map<String, dynamic> json)
=> _$LeistungDataFromJson(json);
Map<String, dynamic> toJson() => _$LeistungDataToJson(this);
}
I hope I was clear and didn't forget anything, just write to me if Im missing something
convert to nullable list.
replace final List <LeistungData> leistungData; with final List <LeistungData>? leistungData;
also try final String? title ;
let me know if it fails to solve the error.
I'm trying to show a list of tweets using Twitter API, using the fromJson factory.
Each tweet object has an extended_entities object which is an array of media objects.
If you're not familiar with the Twitter API you can see all the different objects here.
Here are the models i created in order to achieve this:
class Tweet {
final String createdAt;
final int id;
final String idStr;
final String text;
final String inReplyToStatusIdStr;
final String inReplyToUserIdStr;
final TweetExtendedEntities tweetExtendedEntities;
Tweet(
{this.createdAt,
this.id,
this.idStr,
this.text,
this.inReplyToStatusIdStr,
this.inReplyToUserIdStr,
this.tweetExtendedEntities});
factory Tweet.fromJson(Map<String, dynamic> json) {
return new Tweet(
createdAt: json['created_at'] as String,
id: json['id'] as int,
idStr: json['id_str'] as String,
text: json['text'] as String,
inReplyToStatusIdStr: json['in_reply_to_status_id_str'] as String,
inReplyToUserIdStr: json['in_reply_to_user_id_str'] as String,
tweetExtendedEntities: json['extended_entities'] as TweetExtendedEntities,
);
}
}
class TweetExtendedEntities {
final List<TweetMedia> tweetMedia;
TweetExtendedEntities({this.tweetMedia});
factory TweetExtendedEntities.fromJson(Map<String, dynamic> json) {
return new TweetExtendedEntities(
tweetMedia: json['media'] as List<TweetMedia>);
}
}
class TweetMedia {
final String mediaType;
final String mediaUrl;
TweetMedia({this.mediaType, this.mediaUrl});
factory TweetMedia.fromJson(Map<String, dynamic> json) {
return new TweetMedia(
mediaType: json['type'] as String,
mediaUrl: json['media_url'] as String,
);
}
}
Before i tried to get the extended_entities object everything was fine and i successfully got the JSON data and parsed it, but when i try to get the media objects using the code above, i get this error:
I/flutter (29538): type '_InternalLinkedHashMap<String, dynamic>' is not a subtype of type 'TweetExtendedEntities' in type cast where
I/flutter (29538): _InternalLinkedHashMap is from dart:collection
I/flutter (29538): String is from dart:core
I/flutter (29538): TweetExtendedEntities is from package:pubg_companion/models/tweet.dart
How can i get nested JSON objects using factory or any other way?
Dart has no idea that your JSON structure will correspond to your object, or how. You can't directly cast the JSON (which is probably a Map<String, dynamic>, but could also be other things) to your objects. #betorcs answer is a start in the right direction but needs a bit more.
This line:
tweetExtendedEntities: json['extended_entities'] as TweetExtendedEntities,
Needs to be
tweetExtendedEntities: TweetExtendedEntities.fromJson['extended_entities'],
And your TweetExtendedEntities method should look more like this:
factory TweetExtendedEntities.fromJson(Map<String, dynamic> json) {
return new TweetExtendedEntities(
tweetMedia: createTweetMediaList(json['media']));
}
static List<TweetMedia> createTweetMediaList(List json) {
if (json == null) return null;
if (json.isEmpty) return [];
return json.map((tweetMediaJson) => TweetMedia.fromJson(tweetMediaJson)).toList();
}
You could also certainly look into json_serializable if your needs start getting more complicated and you want to try to generate some of this code.
Your json parameter is Map<String, dynamic>, dynamic is not TweetExtendedEntities, but it can be cast to Map.
factory Tweet.fromJson(Map<String, dynamic> json) {
return new Tweet(
createdAt: json['created_at'] as String,
id: json['id'] as int,
idStr: json['id_str'] as String,
text: json['text'] as String,
inReplyToStatusIdStr: json['in_reply_to_status_id_str'] as String,
inReplyToUserIdStr: json['in_reply_to_user_id_str'] as String,
tweetExtendedEntities: TweetExtendedEntities.fromJson(json['extended_entities'] as Map),
);
}
In flutter, this error will be thrown when you pass a string without json.decode() to the fromjson factory
eg:
Map bodyJson = json.decode(loginResponse.body);
var login = new LoginResponse.fromJson(bodyJson);
The LoginResponse class
class LoginResponse {
int responseCode;
String message;
String responseObject;
LoginResponse();
factory LoginResponse.fromJson(Map<String, dynamic> json) => _$LoginResponseFromJson(json);
}
JSON and serialization in Flutter
I am trying to map my JSON file into a class object, and then update the cards based on the newly received JSON.
My JSON structure is like this
{
"$class": "FirstCard",
"id": "1",
"description": "I am card number one",
"Role": "attack",
"score": 0,
"tag": [
"string"
],................}
my Class looks like this:
class CardInfo {
//Constructor
String id;
String description;
String role;
int score;
}
How can I map the values in my JSON file into the fields of objects created from CardInfo class?
Update
the following trial prints null at ci.description, does this mean the object was never created ?
const jsonCodec = const JsonCodec
_loadData() async {
var url = 'myJsonURL';
var httpClient = createHttpClient();
var response =await httpClient.get(url);
print ("response" + response.body);
Map cardInfo = jsonCodec.decode(response.body);
var ci = new CardInfo.fromJson(cardInfo);
print (ci.description); //prints null
}
Update2
Printing cardInfo gives the following:
{$class: FirstCard, id: 1, description: I am card number one,........}
Note that it resembles the original JSON but without the double quotes on string values.
class CardInfo {
//Constructor
String id;
String description;
String role;
int score;
CardInfo.fromJson(Map json) {
id = json['id'];
description = json['description'];
role = json['Role'];
score = json['score'];
}
}
var ci = new CardInfo.fromJson(myJson);
You can use source generation tools like https://github.com/dart-lang/source_gen https://pub.dartlang.org/packages/json_serializable to generate the serialization and deserialization code for you.
If you prefer using immutable classes https://pub.dartlang.org/packages/built_value is a good bet.
If you want to get your JSON from a url do as follows:
import 'dart:convert';
_toObject() async {
var url = 'YourJSONurl';
var httpClient = createHttpClient();
var response =await httpClient.get(url);
Map cardInfo = JSON.decode(response.body);
var ci = new CardInfo.fromJson(cardInfo);
}
Please refer to the main answer if you want to know how to setup your class so that your JSON fields can be mapped to it. It is very helpful.
I created some useful library for this using reflection called json_parser which is available at pub.
https://github.com/gi097/json_parser
You can add the following to your dependencies.yaml:
dependencies:
json_parser: 0.1.1
build_runner: 0.8.3
Then the json can be parsed using:
DataClass instance = JsonParser.parseJson<DataClass>(json);
Follow the README.md for more instructions.
The best solution I've found is this medium post
Which converts the Json to dart very easily
import 'package:json_annotation/json_annotation.dart';
part 'post_model.g.dart';
#JsonSerializable()
class PostModel {
int userId;
int id;
String title;
String body;
PostModel(this.userId, this.id, this.title, this.body);
factory PostModel.fromJson(Map<String, dynamic> json) => _$PostModelFromJson(json);
Map<String, dynamic> toJson() => _$PostModelToJson(this);
}
You can generate them if you don't want to create them manually.
Add dependecies to pubspec.yaml:
dependencies:
json_annotation: ^4.0.0
dev_dependencies:
build_it: ^0.2.5
json_serializable: ^4.0.2
Create configurtion file my_classes.yaml:
---
format:
name: build_it
generator:
name: build_it:json
---
checkNullSafety: true
classes:
- name: CardInfo
fields:
- { name: id, type: String? }
- { name: description, type: String? }
- { name: role, type: String?, jsonKey: { name: Role } }
- { name: score, type: int? }
- { name: tag, type: List<String>, jsonKey: { defaultValue: [] } }
Run build process:
dart run build_runner build
Generated code my_classes.g.dart:
// GENERATED CODE - DO NOT MODIFY BY HAND
import 'package:json_annotation/json_annotation.dart';
part 'my_classes.g.g.dart';
// **************************************************************************
// build_it: build_it:json
// **************************************************************************
#JsonSerializable()
class CardInfo {
CardInfo(
{this.id, this.description, this.role, this.score, required this.tag});
/// Creates an instance of 'CardInfo' from a JSON representation
factory CardInfo.fromJson(Map<String, dynamic> json) =>
_$CardInfoFromJson(json);
String? id;
String? description;
#JsonKey(name: 'Role')
String? role;
int? score;
#JsonKey(defaultValue: [])
List<String> tag;
/// Returns a JSON representation of the 'CardInfo' instance.
Map<String, dynamic> toJson() => _$CardInfoToJson(this);
}
Now you can use them.
this pkg can help you convert JSON to a class instance. https://www.npmjs.com/package/class-converter
import { property, toClass } from 'class-convert';
class UserModel {
#property('i')
id: number;
#property()
name: string;
}
const userRaw = {
i: 1234,
name: 'name',
};
// use toClass to convert plain object to class
const userModel = toClass(userRaw, UserModel);
// you will get a class, just like below one
{
id: 1234,
name: 'name',
}
Since Flutter took out dart: mirrors off of its SDK, it's no longer possible to use libraries like dartson for JSON to object serialization/deserialization. However I've read that built_value is another way of achieving a similar purpose. I couldn't find any good examples on how to implement it as it contains a significant amount of boilerplate code. Can someone give me an example? For instance, this is the JSON I'm trying to serialize to objects:
{
"name":"John",
"age":30,
"cars": [
{ "name":"Ford", "models":[ "Fiesta", "Focus", "Mustang" ] },
{ "name":"BMW", "models":[ "320", "X3", "X5" ] },
{ "name":"Fiat", "models":[ "500", "Panda" ] }
]
}
I was hoping for more details from the answers provided. Even though they were good suggestions, they were too general for me to understand. So after doing my own research, I'll share my implementation to the above JSON example I provided in hope that it would save someone's else's time. So here are the steps I followed:
In my Flutter project, first I imported the following libraries:
dependencies:
built_value: ^1.0.1
built_collection: ^1.0.0
dev_dependencies:
build_runner: ^0.3.0
built_value_generator:^1.0.1
I created a folder called tool. In it, I put 2 files: build.dart and watch.dart. There implementations of those files are show below
build.dart
// Copyright (c) 2015, Google Inc. Please see the AUTHORS file for details.
// All rights reserved. Use of this source code is governed by a BSD-style
// license that can be found in the LICENSE file.
import 'dart:async';
import 'package:build_runner/build_runner.dart';
import 'package:built_value_generator/built_value_generator.dart';
import 'package:source_gen/source_gen.dart';
/// Example of how to use source_gen with [BuiltValueGenerator].
///
/// Import the generators you want and pass them to [build] as shown,
/// specifying which files in which packages you want to run against.
Future main(List<String> args) async {
await build(
new PhaseGroup.singleAction(
new GeneratorBuilder([new BuiltValueGenerator()]),
new InputSet('built_value_example', const [
'lib/model/*.dart',
'lib/*.dart',
])),
deleteFilesByDefault: true);
}
watch.dart
// Copyright (c) 2016, Google Inc. Please see the AUTHORS file for details.
// All rights reserved. Use of this source code is governed by a BSD-style
// license that can be found in the LICENSE file.
import 'dart:async';
import 'package:build_runner/build_runner.dart';
import 'package:built_value_generator/built_value_generator.dart';
import 'package:source_gen/source_gen.dart';
/// Example of how to use source_gen with [BuiltValueGenerator].
///
/// This script runs a watcher that continuously rebuilds generated source.
///
/// Import the generators you want and pass them to [watch] as shown,
/// specifying which files in which packages you want to run against.
Future main(List<String> args) async {
watch(
new PhaseGroup.singleAction(
new GeneratorBuilder([new BuiltValueGenerator()]),
new InputSet('built_value_example', const [
'lib/model/*.dart',
'lib/*.dart'])),
deleteFilesByDefault: true);
}
I created a serializers.dart file that would serialize my json string to my custom dart object, and my model object person.dart
serializers.dart
library serializers;
import 'package:built_collection/built_collection.dart';
import 'package:built_value/serializer.dart';
import 'package:built_value/standard_json_plugin.dart';
import 'model/person.dart';
part 'serializers.g.dart';
Serializers serializers = (
_$serializers.toBuilder()..addPlugin(new StandardJsonPlugin())
).build();
person.dart
library person;
import 'package:built_collection/built_collection.dart';
import 'package:built_value/built_value.dart';
import 'package:built_value/serializer.dart';
part 'person.g.dart';
abstract class Person implements Built<Person, PersonBuilder> {
String get name;
int get age;
BuiltList<Car> get cars;
Person._();
factory Person([updates(PersonBuilder b)]) = _$Person;
static Serializer<Person> get serializer => _$personSerializer;
}
abstract class Car implements Built<Car, CarBuilder> {
String get name;
BuiltList<String> get models;
Car._();
factory Car([updates(CarBuilder b)]) = _$Car;
static Serializer<Car> get serializer => _$carSerializer;
}
After creating the 4 files above, it will show some compiler errors. Don't mind them yet. This is because the build.dart file hasn't been run yet. So in this step, run build.dart. If you're using Webstorm, simply right click on build.dart and hit "Run build.dart". This will create 2 files: "person.g.dart" and "serializers.g.dart". If you notice carefully, in our build.dart file, we put 'lib/model/.dart' and 'lib/.dart'. The build knows where to look for those files by going through the paths specified and looks for files which have part "something" included. So it's important to keep that line in those files before running the build.dart file
Finally, now I can use the serializer in my main.dart file to serialize the json string to my custom dart object class Person. In my main.dart, I added the following code in initState()
main.dart
Person _person;
#override
void initState() {
super.initState();
String json = "{"
"\"name\":\"John\",\"age\":30,\"cars\": "
"["
"{ \"name\":\"Ford\", \"models\":[ \"Fiesta\", \"Focus\", \"Mustang\" ] },"
"{ \"name\":\"BMW\", \"models\":[ \"320\", \"X3\", \"X5\" ] },"
"{ \"name\":\"Fiat\", \"models\":[ \"500\", \"Panda\" ] }"
"]}";
setState(() {
_person = serializers.deserializeWith(
Person.serializer, JSON.decode(json));
});
}
My sample project is also available on Github Built value sample project
json_serialization
This package by the Dart Team generates everything needed for the fromJson constructor and toJson method in a seprate file.
Dependencies
Add the following dependencies:
dependencies:
json_annotation: ^2.0.0
dev_dependencies:
build_runner: ^1.0.0
json_serializable: ^2.0.0
Model class
Adapt your model class to have the following parts:
import 'package:json_annotation/json_annotation.dart';
// will be generated later
part 'person.g.dart';
#JsonSerializable()
class Person {
Person(this.name, this.age);
final String name;
final int age;
factory Person.fromJson(Map<String, dynamic> json) =>
_$PersonFromJson(json);
Map<String, dynamic> toJson() => _$PersonToJson(this);
}
Generate code
Generate the person.g.dart file from the terminal:
flutter packages pub run build_runner build
Use it
Then use it like this:
JSON → object
String rawJson = '{"name":"Mary","age":30}';
Map<String, dynamic> map = jsonDecode(rawJson);
Person person = Person.fromJson(map);
Object → JSON
Person person = Person('Mary', 30);
Map<String, dynamic> map = person.toJson();
String rawJson = jsonEncode(map);
Notes
In a Dart project use pub run build_runner build.
See this answer for more ways to serialize JSON.
From the Dart web site:
The dart:convert library provides a JsonCodec class, which you can use to convert simple types (map, list, int, num, string) automatically from a and to a JSON string. The two key static methods are JSON.encode(object) and JSON.decode(string).
Decoding example:
import 'dart:convert';
...
Map<String, dynamic> parsedMap = JSON.decode(json);
print(parsedMap['name']); // John
print(parsedMap['age']); // 30
Encoding example:
Map<String, dynamic> mapData = <String, dynamic>{ 'hello': 'world!' };
String jsonData = JSON.encode(mapData); // convert map to String
If you want to have your JSON inflate into custom Dart classes instead of a tree of primitive objects, Hadrien's answer should point you in the right direction, but I just wanted to leave this here in case anyone else is trying to get basic JSON serialization/deserialization working.
You can use Jaguar Serializer, it is easy to start and work perfectly for Flutter, or Server and Web dev.
https://github.com/Jaguar-dart/jaguar_serializer
You should prepare a configuration file for Built_value that will parse you dart source and generate the .g.dart. Once there are ready json serialisation is automatic. You can generate those files once or using a watch command.
Those file will be added at the same level than the source and the dart command
part of data;
to be seen as the same Class.
Here's the config I'm using with my Flutter project :
import 'dart:async';
import 'package:build_runner/build_runner.dart';
import 'package:built_value_generator/built_value_generator.dart';
import 'package:source_gen/source_gen.dart';
Future main(List<String> args) async {
await build(
new PhaseGroup.singleAction(
new GeneratorBuilder([
new BuiltValueGenerator(),
]),
new InputSet('flutter_project', const ['lib/data/*.dart'])),
deleteFilesByDefault: true);
}
You may find useful to read all the posts by David Morgan to understand the benefits. It need some time to turn your mind around but it's a very good pattern.
https://medium.com/dartlang/darts-built-value-for-immutable-object-models-83e2497922d4
https://medium.com/dartlang/darts-built-value-for-serialization-f5db9d0f4159
The trick is to understand how sourcegen parse and then enrich your classes by adding a lot of behaviors like Builders and Serializers.
1) first put json code to any convert website ex:
[JSON to Darthttps://javiercbk.github.io ›][1]
it will give like this output
class Autogenerated {
int? code;
List<Result>? result;
String? status;
Autogenerated({this.code, this.result, this.status});
Autogenerated.fromJson(Map<String, dynamic> json) {
code = json['code'];
if (json['result'] != null) {
result = <Result>[];
json['result'].forEach((v) {
result!.add(new Result.fromJson(v));
});
}
status = json['status'];
}
Map<String, dynamic> toJson() {
final Map<String, dynamic> data = new Map<String, dynamic>();
data['code'] = this.code;
if (this.result != null) {
data['result'] = this.result!.map((v) => v.toJson()).toList();
}
data['status'] = this.status;
return data;
}
}
class Result {
int? id;
int? projectId;
String? projectName;
int? userId;
String? userName;
Result(
{this.id, this.projectId, this.projectName, this.userId, this.userName});
Result.fromJson(Map<String, dynamic> json) {
id = json['id'];
projectId = json['project_id'];
projectName = json['project_name'];
userId = json['user_id'];
userName = json['user_name'];
}
Map<String, dynamic> toJson() {
final Map<String, dynamic> data = new Map<String, dynamic>();
data['id'] = this.id;
data['project_id'] = this.projectId;
data['project_name'] = this.projectName;
data['user_id'] = this.userId;
data['user_name'] = this.userName;
return data;
}
}
