2. Add Spotify_sdk package -> flutter pub add spotify_sdk
3. Run auto setup for android -> dart run spotify_sdk:android_setup
4. Run -> flutter build apk
5. Try to listen the function SpotifySdk.subscribeConnectionStatus()
6. Use the function SpotifySdk.connectToSpotifyRemote() to sign in
7. Nothing happens (The connection status event is not working).

That bug only happens in release mode (on Android), where the Connection Status does not work correctly due to probably a parsing problem.

Found out that:

In the function ConnectionStatus _$ConnectionStatusFromJson(Map<String, dynamic> json) in the file:

"C:\Users{USERNAME}\AppData\Local\Pub\Cache\hosted\pub.dev\spotify_sdk-3.0.2\lib\models\connection_status.g.dart"

The parameter json is filled with keys:'a', 'b', 'c' and 'd' when in release mode, instead of 'connected', 'message', 'errorCode' and 'errorDetails'. The values are ok but the json keys are wrong.

As a temporary workaround I modified two files:

First, I added this import at the very top of the file: C:\Users\{USERNAME}\AppData\Local\Pub\Cache\hosted\pub.dev\spotify_sdk-3.0.2\lib\models\connection_status.dart

import 'package:flutter/foundation.dart';

Second, I modified this function on the file: C:\Users\{USERNAME}\AppData\Local\Pub\Cache\hosted\pub.dev\spotify_sdk-3.0.2\lib\models\connection_status.g.dart

ConnectionStatus _$ConnectionStatusFromJson(Map<String, dynamic> json) {
  if (kReleaseMode) {
    return ConnectionStatus(
      json['b'] as String?,
      json['c'] as String?,
      json['d'] as String?,
      connected: json['a'] as bool,
    );
  } else {
    return ConnectionStatus(
      json['message'] as String?,
      json['errorCode'] as String?,
      json['errorDetails'] as String?,
      connected: json['connected'] as bool,
    );
  }
}

After the changes ConnectionStatus seems to work properly.
