Я хочу интегрировать mapbox с помощью flutter То, что я делаю, это просто устанавливаю свой sdk в pubsec.yaml и помещаю токен доступа в файл манифеста Android и Info.plist

Вот мой pubsec.yaml, куда я добавляю mapbox_gl

 dependencies:
  flutter:
    sdk: flutter

  # The following adds the Cupertino Icons font to your application.
  # Use with the CupertinoIcons class for iOS style icons.
  cupertino_icons: ^0.1.2
  mapbox_gl: ^0.0.3
  

Я еще не добавил никакого кода в файл dart и просто пытаюсь запустить приложение, но оно выдает ошибку

Любая помощь приветствуется.

Это проблема совместимости с AndroidX.

Добавьте это в свой android/gradle.properties и попробуйте построить снова:

 android.enableJetifier=true
android.useAndroidX=true
