Неразрешенная ссылка: io, неразрешенная ссылка: Flutteractivity ⇐ Android

[Anonymous]

неразрешенная ссылка: IO и неразрешенная ссылка: ошибка FlutterActivity, когда пытайтесь развевать построение APK.
Пробое решение: я открываю папку Android на Android Stustio и некоторую загрузку зависимости.e: file:///C:/flutterprojects/apkteerkhelo99/android/app/src/main/kotlin/com/example/teerkhelo99/MainActivity.kt:5:8 Unresolved reference: io
