В выпуске apk виден только серый экран Flutter

Question

Я хотел создать релизный apk для своего приложения и попытался запустить эту команду

      flutter build apk --target-platform android-arm,android-arm64,android-x64 --split-per-abi

Затем я запустил apk app-armeabi-v7a-release, это был только серый экран.

Я также включил все разрешения в манифесте

<uses-permission android:name="android.permission.INTERNET"/>

Заранее спасибо!

Answer 1

После 2 часов поисков я нашел решение.

В моем случае это из-за пакета flutter_downloader.

добавить блок try catch в main следующим образом:

      void main() async {
  try {
    WidgetsFlutterBinding.ensureInitialized();
    await FlutterDownloader.initialize(
        debug: true // optional: set false to disable printing logs to console
        );
    await Firebase.initializeApp();

    final Directory directory =
        await path_provider.getApplicationDocumentsDirectory();
    Hive.init(directory.path);
    Hive.registerAdapter(ResponseTokenModelAdapter());
    await Hive.openBox<ResponseTokenModel>(HiveBoxNames.token);
    configureInjection(Environment.prod);
    runApp(AppWidget());
  } catch (e) {
    runApp(MaterialApp(
      home: Center(
        child: Text(e.toString()),
      ),
    ));
  }
}

Теперь мне просто нужно добавить встроенную интеграцию.
