android - Problem with spotify_sdk connection in flutter

Question

I am newbie in Flutter and with the Spotify SDK. I am using spotify_sdk 2.1.0 Here is my code :

 Future<void> connect() async {
    print("BEGIN");
    try {
      await SpotifySdk.connectToSpotifyRemote(
          clientId: "<ID>", redirectUrl: "copilot://callback");

      var isActive = await SpotifySdk.isSpotifyAppActive;
      String snackBar = isActive
              ? 'Spotify app connection is active (currently playing)'
              : 'Spotify app connection is not active (currently not playing)';

      print(snackBar);

    } on PlatformException catch (e) {
      print("PE");
    } on MissingPluginException {
      print("MPE");
    } on Exception {
      print('what');
    }
  }

  Future<void> disconnect() async {
    try {
      var result = await SpotifySdk.disconnect();
    } on PlatformException catch (e) {
      print("PlatExcep");
    } on MissingPluginException {
      print("sd");
    }
  }

I want to connect to Spotify App in Flutter and skip song with my app but when i try to connect I have this :

After this I tried to skip the song but it did not works.

And when I try to disconnect, I have this :

I don't know if my question is stupid but didn't find any solutions on Internet.
