Why my app is showing App with name __FIRAPP_DEFAULT does not exist

Question

I am developing flutter ios app with frebase. I want to login to the app using sms authentication. When i am running the app it is fetching details from db. But it is showing the error in app launching time. The error is - [Firebase/Core][I-COR000004] App with name __FIRAPP_DEFAULT does not exist.

In the xcode i have enabled the enabled "Push Notifications" and "Remote Notifications" for removing captcha in OTP verification. But if i disabled "Push Notifications" and "Remote Notifications" it will show captcha. And after verifying captcha it send SMS. - [Firebase/Core][I-COR000004] App with name __FIRAPP_DEFAULT does not exist. in application open. i given below main.dart file

   final FirebaseApp app = await FirebaseApp.configure(
      name: myApp,
      options: const FirebaseOptions(
        googleAppID: '1:57979xxxxx:ios:c9d1031xx',
        gcmSenderID: '58989xxxxx6',
        apiKey: 'AIzaSyANwavsssasxxxxxxxxxxxKBNF7I',
        projectID: 'myApp',
      ),
   );

The SMS verification code is

  await firebaseAuth.verifyPhoneNumber(
      phoneNumber: "+91"+phoneNumber,
      timeout: Duration(seconds: timeOut),
      codeAutoRetrievalTimeout: autoRetrieve,
      codeSent: smsCodeSent,
      verificationCompleted: verifiedSuccess,
      verificationFailed: veriFailed);

    final PhoneVerificationFailed veriFailed = (AuthException exception) {
    print("ERROR");
    print('${exception.message}');
    throw new Exception(exception);
  };

When i enabled "Push Notifications" and "Remote Notifications"

It will show the error in "veriFailed" function . The error is Invalid Token and

PlatformException(ERROR_MISSING_VERIFICATION_ID, The phone auth credential was created with an empty verification ID., null)

Answer 1

Swap lines in AppDelegate.swift to FirebaseApp is called before plugin.

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

Answer 2

I solve the by changing auth plugin to

firebase_auth:
  git:
    url: https://github.com/collinjackson/plugins.git
    ref: 441417c2fed0ff26bf84a49ab2c5ffd2aa5487de
    path: packages/firebase_auth

After adding the plugin the problem solved. The plugin firebase_auth: ^0.11.1+11 is making the issues
