Я получаю сообщение об ошибке «привязка еще не инициализирована» при попытке подключить Firebase с флаттером. ⇐ IOS

[Anonymous]

Пожалуйста, мы будем благодарны за любую помощь, но поиск в Google, похоже, не дает здесь никаких правильных решений. Что меня еще больше смущает, так это то, что эта ошибка теперь появляется даже при попытке запуска приложений без Firebase или даже асинхронных функций, что делает для меня практически невозможным выполнение чего-либо еще во Flutter.
Я пытался изучить Firebase и получил выполнил шаги, показанные здесь, без особых проблем.
При поиске в Google решения проблемы, с которой я столкнулся (сообщение об ошибке в конце сообщения), обычное исправление, которое я видел, — это добавление только этой строки в основную функцию. .

Код: Выделить всё

WidgetsFlutterBinding.ensureInitialized();

Однако он у меня уже есть, и я все равно снова получаю ту же ошибку. Вот моя основная функция void.

Код: Выделить всё

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

Вот какая ошибка:

Как уже говорилось, WidgetsFlutterBinding.ensureInitialized() не работает.
Я не уверен, поможет ли это, но я попытался запустить следующую команду gradle:

cd android
./gradlew build --warning-mode all

и получите следующий вывод в терминале:

Что меня больше всего беспокоит, так это то, что теперь ни один из моих проектов Flutter не работает и все показывают одну и ту же ошибку, даже те, к которым не подключена Firebase. На данный момент я даже не уверен, является ли это проблемой с Firebase или чем-то еще.
Я не знаю, как это интерпретировать, но надеюсь, что кто-то более знающий, чем я, поможет мне понять.
