Я обновился до FLutter 2.0.1, и теперь я не могу запустить свое приложение. Это ошибка, которая у меня есть:

Я пробовал некоторые онлайн-решения, такие как flutter clean и flutter run, но это не работает.
Можете ли вы помочь мне решить эту проблему? Спасибо вам, и я действительно ценю это.

Проблема была вызвана webview_flutter плагином, использующим устаревшую функцию в iOS 9. Более подробная информация обсуждается в этом выпуске. Эта проблема должна быть исправлена в последней версии плагина.
