Execution failed for task ':app:cleanMergeDebugAssets' while running the app in flutter

The problem was with the Kotlin plugin in VS Code, so removing it should fix our problem!

Now I able to run the project in debug mode. Below is my flutter doctor

Doctor summary (to see all details, run flutter doctor -v):

I reinstall the Kotlin plugin in VS Code, the problem came back. I removed it, the project runs. So I guess its the plugin. The plugin I used and removed is Kotlin 0.2.17

Can anyone double-check whether the problem is because of this?

Uninstalling the Kotlin 0.2.18 extension on VSCode worked for me. I didn't need to delete the build and .dart_tool files mentioned above.
