Flutter Не удалось обработать вызов метода. java .lang.IllegalStateException: FirebaseApp с именем [DEFAULT] не существует

Question

У меня проблема с firebase в моем приложении. Я делаю OTP с firebase в моем приложении. Но возникла такая проблема при попытке отправить номер телефона:

E/MethodChannel#plugins.flutter.io/firebase_auth(19880): Failed to handle method call

Я добавил google-сервисы. json в android / app. И я добавил эти зависимости в android / build.gradle, а также попытался изменить разные версии, но приложение работало только с 4.1.0:

dependencies {
        classpath 'com.android.tools.build:gradle:3.5.3'
        classpath "org.jetbrains.kotlin:kotlin-gradle-plugin:$kotlin_version"
        // Add the google services classpath
        classpath 'com.google.gms:google-services:4.1.0'
    }

В конце в android / app / build.gradle также добавлено применить плагин:

dependencies {
    implementation "org.jetbrains.kotlin:kotlin-stdlib-jdk7:$kotlin_version"
    implementation 'androidx.annotation:annotation:1.1.0'
    implementation 'androidx.localbroadcastmanager:localbroadcastmanager:1.0.0'
    testImplementation 'junit:junit:4.12'
    androidTestImplementation 'androidx.test:runner:1.1.1'
    androidTestImplementation 'androidx.test.espresso:espresso-core:3.1.1'
    implementation 'com.google.firebase:firebase-core:17.0.0'
}

apply plugin: 'com.google.gms.google-services'

Вот мой исходный код:

void _onVerifyCode() async {
    setState(() {
      isCodeSent = true;
    });
    final PhoneVerificationCompleted verificationCompleted =
        (AuthCredential phoneAuthCredential) {
      _firebaseAuth
          .signInWithCredential(phoneAuthCredential)
          .then((AuthResult value) {
        if (value.user != null) {
          // Handle loogged in state
          print(value.user.phoneNumber);
          Navigator.pushAndRemoveUntil(
              context,
              MaterialPageRoute(
                builder: (context) => HomeWidget(
                  user: value.user,
                ),
              ),
              (Route<dynamic> route) => false);
        } else {
          showToast("Error validating OTP, try again", Colors.red);
        }
      }).catchError((error) {
        showToast("Try again in sometime", Colors.red);
      });
    };
    final PhoneVerificationFailed verificationFailed =
        (AuthException authException) {
      showToast(authException.message, Colors.red);
      setState(() {
        isCodeSent = false;
      });
    };

    final PhoneCodeSent codeSent =
        (String verificationId, [int forceResendingToken]) async {
      _verificationId = verificationId;
      setState(() {
        _verificationId = verificationId;
      });
    };
    final PhoneCodeAutoRetrievalTimeout codeAutoRetrievalTimeout =
        (String verificationId) {
      _verificationId = verificationId;
      setState(() {
        _verificationId = verificationId;
      });
    };

    // TODO: Change country code

    await _firebaseAuth.verifyPhoneNumber(
        phoneNumber: "+90${widget.mobileNumber}",
        timeout: const Duration(seconds: 60),
        verificationCompleted: verificationCompleted,
        verificationFailed: verificationFailed,
        codeSent: codeSent,
        codeAutoRetrievalTimeout: codeAutoRetrievalTimeout);
  }

  void _onFormSubmitted() async {
    AuthCredential _authCredential = await PhoneAuthProvider.getCredential(
        verificationId: _verificationId, smsCode: _pinEditingController.text);

    _firebaseAuth
        .signInWithCredential(_authCredential)
        .then((AuthResult value) {
      if (value.user != null) {
        // Handle loogged in state
        print(value.user.phoneNumber);
        Navigator.pushAndRemoveUntil(
            context,
            MaterialPageRoute(
              builder: (context) => HomeWidget(
                user: value.user,
              ),
            ),
            (Route<dynamic> route) => false);
      } else {
        showToast("Error validating OTP, try again", Colors.red);
      }
    }).catchError((error) {
      showToast("Something went wrong", Colors.red);
    });
  }

Очистка флаттера тоже не сработала!
