Firebase won't initialize

This is my main.dart where I'm calling firebase

`Future<void> main() async {
  // final int helloAlarmID = 0;

  SharedPreferences.setMockInitialValues({});
  if (Platform.isAndroid) SharedPreferencesAndroid.registerWith();
  if (Platform.isIOS) SharedPreferencesIOS.registerWith();

  DartPluginRegistrant.ensureInitialized();
  WidgetsFlutterBinding.ensureInitialized();
  await Firebase.initializeApp(
    options: DefaultFirebaseOptions.currentPlatform,
  );
etc
etc
etc
runApp(MyApp());
`

Output of flutter doctor -v

`Future main() async { // final int helloAlarmID = 0;

SharedPreferences.setMockInitialValues({}); if (Platform.isAndroid) SharedPreferencesAndroid.registerWith(); if (Platform.isIOS) SharedPreferencesIOS.registerWith();

DartPluginRegistrant.ensureInitialized(); WidgetsFlutterBinding.ensureInitialized(); await Firebase.initializeApp( options: DefaultFirebaseOptions.currentPlatform, ); etc etc etc runApp(MyApp()); `

@absolutelydigital WidgetsFlutterBinding.ensureInitialized(); should be the first line inside main() method followed by Firebase.initializeApp(). Also, not sure why are you using DartPluginRegistrant.ensureInitialized();.

So updated main() method should be:

Future<void> main() async {
  WidgetsFlutterBinding.ensureInitialized();
  await Firebase.initializeApp(options: DefaultFirebaseOptions.currentPlatform);
 // SharedPreferences related code here
 // runApp(MyApp());

Try above and see if it helps or not.

If not, provide flutter doctor -v, pubspec.yaml in properly formatted text.

absolutelydigital commented 2 years ago

hello @darshankawar , this didn't work. it is worth noting that the project was built way before null-safety and still wasn't upgraded.

please find below the pubspec.yaml

name: stepchain
description: A responsible fitness app

# The following defines the version and build number for your application.
# A version number is three numbers separated by dots, like 1.2.43
# followed by an optional build number separated by a +.
# Both the version and the builder number may be overridden in flutter
# build by specifying --build-name and --build-number, respectively.
# In Android, build-name is used as versionName while build-number used as versionCode.
# Read more about Android versioning at https://developer.android.com/studio/publish/versioning
# In iOS, build-name is used as CFBundleShortVersionString while build-number is used as CFBundleVersion.
# Read more about iOS versioning at
# https://developer.apple.com/library/archive/documentation/General/Reference/InfoPlistKeyReference/Articles/CoreFoundationKeys.html
# In Windows, build-name is used as the major, minor, and patch parts
# of the product and file versions while build-number is used as the build suffix.

Tried to run the project with and without --no-sound-null-safety, same result. Debug, Release, Profile everything fails. The application is stuck on splash screen with this error so it is a major block.
