Ну, я написал это, основываясь на моих собственных файлах, уже перенесенных на androidX, и мой проект работает. Я очень надеюсь, что это поможет.
ичок в трепетании, и я создаю очень небольшое приложение, показывающее текущую широту и долготу, что потребовало от меня добавить две зависимости в pubspec.yaml: -
location и simple_permissions для получения текущего местоположения пользователя и запроса разрешения местоположения.
но когда я запустил приложение, оно показывает следующую ошибку: -
Gradle task 'assembleDebug'...
D8: Program type already present: android.support.v4.media.MediaBrowserCompat$CustomActionCallback
FAILURE: Build failed with an exception.

Execution failed for task ':app:transformDexArchiveWithExternalLibsDexMergerForDebug'.

BUILD FAILED in 9s
Finished with error: Gradle task assembleDebug failed with exit code 1
я думаю, что это из-за добавления библиотеки два раза, но я не добавляю зависимости вручную, так что это ошибка флаттера внутри.
Пожалуйста, скажите мне решение этого

# example:
