Flutter Execution failed for task ':audioplayers:compileDebugKotlin'

Question

I tried installing audioplayers: ^0.17.1 and ran my flutter project. It throws the following error. Can someone help, please?

Answer 1

I had been struggling with this issue since morning and finally here are 2 fixes:

Upgrade to flutter 2.0 and then update audioplayers dependency to 0.19.0 in pubspec.yaml

*in the build.gradle change ext.kotlin_version to '1.4.32'

or

If you don't want to upgrade to flutter 2.0 due to some reasons then downgrade your audioplayers dependency to ^0.16.0.

Note: To update Flutter SDK use the flutter upgrade command.

Answer 2

The current latest version is 0.18.0, but I faced the same problem. And I could solve that problem by following Gradle Build Failing.

In order to support the playBytes method, this has a hard requirement on using API >= 23 features, and your build may failure depending on your minimum SDK targeting. To override this, you will need to add <uses-sdk tools:overrideLibrary="xyz.luan.audioplayers"/> to your AndroidManifest.xml file.

If you still facing an error on the compiling, you should change version of kotline following this issue.

faced same issue, fixed by updating ext.kotlin_version to 1.4.31 in android/build.gradle.
