'Execution failed for task ':audioplayers:compileDebugKotlin'
I'm facing this nasty error when trying to compile my Flutter App into an Android simulator. Here is the error log (is too long to paste it entirely):

- I already tried changing "minSdkVersion 16" to "minSdkVersion 23" at android/app/build.gradle:38 and is not working.
- Tried using the version 0.17.0 of audioplayers and the same, not working.
- Tried using the version ^0.10.0 of audioplayers and nothing.
- Tried doing the previos steps and then executing on the terminal: flutter clean & flutter pub get... and nothing.
- I already updated the Flutter SDK and nothing. Still not working for Android.
It compiles perfectly on an IOS simulator. This error has emerged several times after each audioplayers package update. I'm using compileSdkVersion 30 on Android Studio 4.2.1

Solution 1:[1]
Updating to a newer kotlin version in build.gradle seems to solve the issue for me.
ext.kotlin_version = '1.4.32'
Solution 2:[2]
this happened to me after i added the workmanager plugin. to fix this, go to the android folder and in build.gradle use kotlin version 1.5.31
ext.kotlin_version = '1.5.31'
Solution 3:[3]
Please open android > build.gradle
Inside buildscript { }, you'll find ext.kotlin_version (Line 2 in file)
Replace whatever version it is with Latest Stable Kotlin Version
As of July 28, 2021 it is, ext.kotlin_version = '1.5.21'
Now, re-install the app. If it's already running, press Stop then press Run (Play) again.

Go to android>build.gradle and update your Kotlin version.
ext.kotlin_version = '1.4.32'
This worked for me.
Solution 5:[5]
As for Flutter 2.10 there was a breaking change with required Kotlin version - Ref.
Here is a migration guide
This means that if you previosly created a project a long time ago (with java) then it means you need to add Kotlin plugin to build.gradle. I suggest launching flutter create --org com.sample sample which generates up-to-date configuration. Then you can check what is missing.

this happened to me after i added the Room plugin. to fix this, go to the android folder and in build.gradle use kotlin version 1.5.31
I changed from
ext { kotlin_version = "1.3.72" nav_version = "2.3.1"
room_version = '2.3.0' }
replace with
ext { kotlin_version = "1.5.31" nav_version = "2.3.1" room_version = '2.3.0' }
Solution 7:[7]
Plese check the current kotlin (installed) version by
ANdroidstudio->Preferences->Languages& frameworks->kotlin
In this 1.6.10 is the version . Now Open Android build.gradle
buildscript {
ext.kotlin_version = '1.6.10'
repositories {
google()
mavenCentral()
}
.....
Change it ..
ext.kotlin_version** = '1.6.10'
