Flutter app breaks when trying to push data to firebase - exception

Question

So I am using the firebase plugin and did everything what google said to connect it to firebase, but if I try to add (create) something, it breaks the app.
This is my firebase setup:
I've downloadaded the google-services.json from firebase
added to application/build.grandle:
dependencies {
classpath 'com.google.gms:google-services:4.2.0'
classpath 'com.android.tools.build:gradle:3.3.2'
classpath "org.jetbrains.kotlin:kotlin-gradle-plugin:$kotlin_version"
}
my grundle file to the application/app/build.grundle
def localProperties = new Properties()
def localPropertiesFile = rootProject.file('local.properties')
if (localPropertiesFile.exists()) {
localPropertiesFile.withReader('UTF-8') { reader ->
localProperties.load(reader)
}
}
def flutterRoot = localProperties.getProperty('flutter.sdk')
if (flutterRoot == null) {
throw new GradleException("Flutter SDK not found. Define location with flutter.sdk in the local.properties file.")
}
def flutterVersionCode = localProperties.getProperty('flutter.versionCode')
if (flutterVersionCode == null) {
flutterVersionCode = '1'
}
def flutterVersionName = localProperties.getProperty('flutter.versionName')
if (flutterVersionName == null) {
flutterVersionName = '1.0'
}
apply plugin: 'com.android.application'
apply plugin: 'kotlin-android'
apply from: "$flutterRoot/packages/flutter_tools/gradle/flutter.gradle"
android {
compileSdkVersion 28
sourceSets {
main.java.srcDirs += 'src/main/kotlin'
}
lintOptions {
disable 'InvalidPackage'
}
defaultConfig {
// TODO: Specify your own unique Application ID (https://developer.android.com/studio/build/application-id.html).
applicationId "com.comp.appname"
minSdkVersion 21
targetSdkVersion 27
versionCode flutterVersionCode.toInteger()
versionName flutterVersionName
testInstrumentationRunner "android.support.test.runner.AndroidJUnitRunner"
}
buildTypes {
release {
// TODO: Add your own signing config for the release build.
// Signing with the debug keys for now, so `flutter run --release` works.
signingConfig signingConfigs.debug
}
}
}
flutter {
source '../..'
}
dependencies {
implementation 'com.google.firebase:firebase-core:16.0.8'
implementation 'com.google.firebase:firebase-firestore:18.1.0'
implementation "org.jetbrains.kotlin:kotlin-stdlib-jdk7:$kotlin_version"
testImplementation 'junit:junit:4.12'
androidTestImplementation 'com.android.support.test:runner:1.0.2'
androidTestImplementation 'com.android.support.test.espresso:espresso-core:3.0.2'
}
apply plugin: 'com.google.gms.google-services'
this is the build with the error

It's probably worth mentioning that I use a proxy but it's configured right, and works with another app

Answer 1

Fixed it,
I had to downgrade build gradle like so:
at myapp/build.gradle
dependencies {
classpath 'com.google.gms:google-services:4.2.0'
classpath 'com.android.tools.build:gradle:3.2.1'
classpath "org.jetbrains.kotlin:kotlin-gradle-plugin:$kotlin_version"
}
and removed everything unnecessary from myapp/app/build.gradle
dependencies {
implementation 'com.google.firebase:firebase-core:16.0.8'
implementation "org.jetbrains.kotlin:kotlin-stdlib-jdk7:$kotlin_version"
testImplementation 'junit:junit:4.12'
}
apply plugin: 'com.google.gms.google-services'
I also removed all unused dependencies like image_picker and firebase_ml_vision
