Flutter: Execution failed for task ':app:compileDebugKotlin'

Question

I tried running the default flutter app from flutter create on my android device but it throws me an error. Can someone help?

Launching lib\main.dart on SM G610F in debug mode... Running Gradle task 'assembleDebug'...

FAILURE: Build failed with an exception.

• What went wrong: Execution failed for task ':app:compileDebugKotlin'.

  Could not resolve all artifacts for configuration ':app:debugCompileClasspath'. . . .

• Try: Run with --stacktrace option to get the stack trace. Run with --info or --debug option to get more log output. Run with --scan to get full insights.

• Get more help at https://help.gradle.org

BUILD FAILED in 14s Finished with error: Gradle task assembleDebug failed with exit code 1

This is my flutter doctor:

Answer 1

Go to your build.gradle file in the root of your Android directory and upgrade your Kotlin_version to the latest. As of the time of typing this, the latest is 1.5.10, so it should look like this:

ext.kotlin_version = '1.5.10'

Answer 2

Solved the problem by deleting android/.gradle and then run the app in debug mode

Answer 3

A possible fix can be upgrading the project/android/build.gradle Steps to fix,

1. flutter clean
2. Delete android/.gradle
3. Go to android/build.gradle, upgrade ext.kotlin_version to latest. In my case(1.3.0 -> 1.5.10), ext.kotlin_version = '1.5.10'

After doing this as well, I was getting `A problem occurred evaluating project ':app'.

Failed to apply plugin [id 'kotlin-android'] The current Gradle version 5.6.2 is not compatible with the Kotlin Gradle plugin. Please use Gradle 6.1 or newer, or the previous version of the Kotlin plugin.`

To fix this,

1. Go to android/gradle/wrapper/gradle-wrapper.properties
2. Update the distributionUrl to the latest version.In my case((5.6.2 -> 6.1.1) it is, distributionUrl=https\://services.gradle.org/distributions/gradle-6.1.1-all.zip
