我想为我的应用程序构建发布 apk，并尝试运行此命令

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

然后，我运行了 app-armeabi-v7a-release apk，它只是灰屏而已。

我还启用了清单中的所有权限

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

灰屏

找了2个小时后，我找到了解决方案。

在我的情况下，这是因为 flutter_downloader 包。

在 main 中添加 try catch bloc，如下所示：

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()),
      ),
    ));
  }
}

错误

现在我只需要添加原生集成。
