CodePudding user response：

Are you initialize Firebase in your project main file?

  WidgetsFlutterBinding.ensureInitialized(),
  if (Platform.isAndroid)
    {
      await Firebase.initializeApp(), // firebase initialize 
    },
  SystemChrome.setPreferredOrientations([DeviceOrientation.portraitUp])
      .then(
    (_) {
      runApp(new MyApp());
    },
  )
};

CodePudding user response：

In main.dart add this code

 WidgetsFlutterBinding.ensureInitialized(),
  if (Platform.isAndroid)
    {
      await Firebase.initializeApp(), // firebase initialize 
    },
  SystemChrome.setPreferredOrientations([DeviceOrientation.portraitUp])
      .then(
    (_) {
      runApp(new MyApp());
    },
  )
};

Secondly In AndroidManifest.xml add

Path: [your App Name]/android/app/src/main/AndroidManifest.xml

It will resolve issue Hopefully.
