for the second issue, you probably have to run gradlew clean to remove inconsistencies... — Jiří

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. from here

You got the following error message in your question:

FAILURE: Build failed with an exception.

* What went wrong:
Execution failed for task ':audioplayers:compileDebugKotlin'.

Remove the audioplayers: ^0.18.2 plugin. Upgrading the plugin can't help this problem.
