Error on Flutter 3

After upgrading to flutter 3.0 I'm unable to build my app, cause this error:

FAILURE: Build failed with an exception.

* What went wrong:
Execution failed for task ':flutter_applovin_max:verifyReleaseResources'.

I have the same problem

Same here, no solution so far, all solutions recommend upgrading to compileSDK 31 and targetSDK 31 , but I think it's this plugin author who should do it in the plugin project. current SDK is 29.

[hakamdev]

As a temp solution, what I basically did was, clone this repo, remove the example folder, and then paste the flutter_applovin_max folder into my own project, and then change the compileSdkVersion 29 to compileSdkVersion 31 inside build.gradle file in the flutter_applovin_max/android directory.
And then inside my own pubspec.yaml file I replaced:

  flutter_applovin_max: ^2.1.1

with:

  flutter_applovin_max:
    path: ./flutter_applovin_max

The path: points to where you pasted the flutter_applovin_max content.
But I don't know if this is Okay to upload to the Play Store!!

Hey there - AppLovin just released an official plugin. Please feel free to check it out here: (docs, repo).

Thank you @ioridev for developing this stop-gap solution, we really appreciate it.
