Flutter iOS app showing white screen on launch and hang up on that screen

I have a flutter application using a firebase auth library. When I launch its iOS version, It shows me a blank white screen and hangs up on that screen. I followed all the steps to add some firebase related flags into Info.plist like FirebaseScreenRecordingEnabled - NO, FirebaseScreenRecordingDeactiv - YES and one or two more. I have tried to clean the build folder and flutter cache. Just also tried this below answer as well: iOS Flutter with Firebase : white screen and SIGABRT in FlutterAppDelegate on launch

~/Documents/Work/Workspaces/flutter/myapp $ flutter doctor

FYI, I am using Android Studio for a flutter app.

Here are the logs from xCode logger:

Make sure to add the following before initializing firebase on your main.dart

WidgetsFlutterBinding.ensureInitialized()

Future<void> main() async {
   WidgetsFlutterBinding.ensureInitialized();
  await Firebase.initializeApp(
  options: DefaultFirebaseOptions.currentPlatform,
);
  runApp(const MyApp());
}

After a lot and lot and lot of struggle, I found the solution.

Just shift the runApp(const MyApp()); on top in the

void main() async {

Issue solved now.

I had the same issue and it was stucking at Blue Screen which was FIXED by adding GoogleService-info.plist in the project. It can be added in Xcode or in iOS folder.

Please check logs if it's attempting to connect to firebase or has any firebase dependencies. If it does, then, check if you have added GoogleService-info.plist. You might be missing that.

After doing the clean, the build folder and run. Hopefully it will work fine.

Could be the package_info_plus plugin, the white screen appear when you invoke the PackageInfo packageinfo = await PackageInfo.from Platform(); method before runApp(App());

As of 28 April 2021, what worked for me (after days of struggle):

in AppDelegate.swift (flutter-project/ios/Runner): Add these 2 lines:

FirebaseApp.configure()
GeneratedPluginRegistrant.register(with: self)

in terminal:

flutter build ios

Then run your project in XCode

Error log clearly saying that

The project's Bundle ID is inconsistent with either the Bundle ID in 'GoogleService-Info.plist', or the Bundle ID in the options if you are using a customized options. To ensure that everything can be configured correctly, you may need to make the Bundle IDs consistent. To continue with this plist file, you may change your app's bundle identifier to 'com.tethys.client'. Or you can download a new configuration file that matches your bundle identifier from https://console.firebase.google.com/ and replace the current one.

Try replacing your GoogleService-Info.plist from iOS project. Make sure it has a valid Bundle ID

Also, Make sure if you are running a below command before creating an archive or before distributing it.

flutter build ios --release

or

flutter build ios

flutter build defaults to --release.
