I can't use last version of permission_handler

[mehmetgencdal]

Hi again @vavadiyahiren @dr7866 ,

Situation 1: When i delete proguard rules the problem doesn't occurs but the app doesn't work for release version. Situation 2: When i use flutter_plugin 2.2.3 and permission_handler 9.2.0 the release version works but 9.2.0 version is not useful.

When it is debug mode everthing is fine but i can't get release verison. I have tried many solutions but none of them work.

Problem: When i use permission_handler above version 9.2.0 with flutter_plugin i have error given below:

I believe that this issue occurs because of android gradle sync. Follow these steps and let me know if it works for you.

1. set latest kotlin version
2. flutter clean
3. open android folder in Android Studio
4. click on the gradle sync
5. go back to project dictionary and flutter run

I tried it but many other problems occurred. For example: Could not create an instance of type com.android.build.api.variant.impl.LibraryVariantBuilderImpl.

I'm trying to fix. Thanks for the answer.

@mehmetgencdal please just downgrade your Permission handler package version

@mehmetgencdal please just downgrade your Permission handler package version

Unfortunately when i downgrade the version the permission handler doesn't work. It doesn't ask for any permission.

I tried to upgrade the gradle version but it always fails. Is there any way to create a project with the latest gradle version? Then i can move the codes? @dr7866 @fadihere
