Error

When I try Android debugging, the errors displayed.

I'm trying to use instagram_basic_display_api package but it doesn't work.

FAILURE: Build completed with 2 failures.

1: Task failed with an exception.

I tried flutter pub remove instagram_basic_display_api, flutter clean and flutter pub get. But still this error.

And the strange thing is that some of the errors are garbled.

> D:\FlutterProjects\project1\android\secret.properties (�w�肳�ꂽ�t�@�C����������܂���B)

If I remove instagram_basic_display_api from pubspec.yaml, build successful.

Also what is this secret.properties? I can't see it with exploror. I didn't change any files in android directory before this error occurs.

flutter doctor -v

I think this is a problem about package, not Flutter own.
