添加初始化firebase_core后，Flutter App卡在加载屏幕上

Question

添加Firebase.initializeApp（）后，我的应用卡住了加载屏幕，没有Firebase.initializeApp（），它显示了我的登录屏幕，但是如果不进行初始化，我将无法使用pubspec.yaml文件中的任何firebase插件firebase_core。

void main() async {
 WidgetsFlutterBinding.ensureInitialized();
   await Firebase.initializeApp();
  runApp(MyApp());
}



class MyApp extends StatelessWidget {
  @override
  Widget build(BuildContext context) {
    return MaterialApp(
      title: 'Flutter Demo',
      theme: themeData(),
      home:Login()
    );
  }

对此进行了尝试，它将在错误屏幕上加载以下错误：将来返回null

void main() async {
WidgetsFlutterBinding.ensureInitialized();
      runApp(MyApp());
    }

    class App extends StatelessWidget {
      @override
      Widget build(BuildContext context) {
        return FutureBuilder(
          // Initialize FlutterFire
          future: Firebase.initializeApp(),
          builder: (context, snapshot) {
            // Check for errors
            if (snapshot.hasError) {
               print(snapshot.error.toString);
               return Error();
            }
    
            // Once complete, show your application
            if (snapshot.connectionState == ConnectionState.done) {
              return Login();
            }
    
            // Otherwise, show something whilst waiting for initialization to complete
            return Loading();
          },
        );
      }
    }
