Error when trying to decode json with Iterable in Flutter - json

Question

I'm trying to get this simple json response in Flutter, but getting this error type '_InternalLinkedHashMap<String, dynamic>' is not a subtype of type 'Iterable< dynamic >'. I found some people with the same error but the solutions it's not clearly to me. The error occurs on jsonDecode(response.body);, in debug mode, when reachs the response.body, the exception occurs.
{
"#bom": 4,
"#jantar": 3,
"#paris": 2,
}
My model:
import 'dart:convert';
List<Hashtags> hashtagsFromJson(String str) => List<Hashtags>.from(json.decode(str).map((x) => Hashtags.fromJson(x)));
String hashtagsToJson(List<Hashtags> data) => json.encode(List<dynamic>.from(data.map((x) => x.toJson())));
class Hashtags {
Hashtags({
this.hashtag,
});
int? hashtag;
factory Hashtags.fromJson(Map<String, dynamic> json) => Hashtags(
hashtag: json["hashtag"],
);
Map<String, dynamic> toJson() => {
"hashtag": hashtag,
};
}
and my get method:
Future<List<Hashtags>> getHashtagTop() async {
var url = Uri.parse(baseUrl + 'hashtagTop');
final Map<String, String> dataBody = new Map<String, String>();
dataBody['uid'] = appController.currentUser.value.id.toString();
try {
http.Response response = await http.post(
url,
headers: headers,
body: jsonEncode(dataBody),
);
if (response.statusCode == 200 || response.statusCode == 201) {
Iterable jsonResponse = jsonDecode(response.body);
List<Hashtags> listHashtagTop =
jsonResponse.map((model) => Hashtags.fromJson(model)).toList();
return listHashtagTop;
} else {
return [];
}
} catch (e) {
print("ERRO_______________" + e.toString());
return [];
}
}
So what is missing here?

Answer 1

Change your decoding function to this
final results = [jsonDecode(response.body)];
List<Hashtags> listHashtagTop =
results.map((model) => Hashtags.fromJson(model)).toList();
Try this and let you know
