Please make sure you have a backup of the project. The permission handler version seems to be too old. Please use version 10.0.0 (latest) if you are using flutter version > 3 or 8.3.0 if less than flutter version 3.. please update the version in pubspec.yaml and try again

please how do i resolve this?

The original package was updated recently, perhaps try the official one from pub.dev - https://pub.dev/packages/plain_notification_token, instead of the forked one from GitHub.
plain_notification_token: 0.0.4

React-native android studio Build Failed

When I do build->rebuild project the build fails in the android studio. I have the error message posted below. This is very strange because I didn't change anything, all I tried was to create a new AVD and the next thing you know trying to build it causes an error. Now I can't get it to run. I am hesitant to try some random quick fix because everything was working fine until I created a new AVD.
