Message "error: resource android:attr/lStar not found"


A Flutter Android app I developed suddenly compiled wrong today.


What went wrong:

Execution failed for task ‘:app:processDebugResources’.

Android resource linking failed

error: failed linking references.

Using the answer from here
Update compileSdkVersion and targetSdkVersion to 31

And add this code snippet in your android/build.gradle file at the very end.

configurations.all {
    resolutionStrategy {
        force 'androidx.core:core-ktx:1.6.0'

Just recently the original author of audioplayers package fixed this issue in his recent PR. It has been fixed in audioplayers version 0.20.1, so if your issue is related to audioplayers, do upgrade.
