依赖覆盖

Running "flutter pub get" in flutter_app...                     

Because every version of flutter_plugin from path depends on path_provider ^0.5.0 and flutter_app depends on path_provider ^1.6.22,flutter_plugin from path is forbidden.
So,because flutter_app depends on flutter_plugin from path,version solving failed.
pub get failed (1; So,version solving failed.)
Process finished with exit code 1

dependency_overrides:
  path_provider: ^1.6.22
