How To Fix The Error: "resource Mipmap/ic_launcher (aka Com.example.MyAppName:mipmap/ic_launcher) Not Found." On Vs Code

- 1 answer

I need some help to fix that issue I'm facing with my chat app. Everything was working great but I left aside the project for some months.And when I started working on it again,I had to upgrade all the packages and flutter itself so that in hope it works. But I don't know why this error occurs, here the complete error :

Execution failed for task ':app:processDebugResources'.> A failure occurred while executing com.android.build.gradle.internal.tasks.Workers$ActionFacade Android resource linking failed D:\MyAppName 2.0\myappname\build\app\intermediates\packaged_manifests\debug\AndroidManifest.xml:19: AAPT: error: resource mipmap/ic_launcher (aka com.example.MyAppName:mipmap/ic_launcher) not found.

I didn't tried to change any name of icon or anything else, so if someone could help me it will be wonderful. Here are my pubspec.yaml file and my AndroidManifest.xml :

   name: MyAppName
    description: A new Flutter project.

    environment:

If you need other files to see, there is absolutely no problem ! Thanks

Answer

it happens because there is a change in flutter. the easy way is to create a new project with the same name, then copy the old files (lib, assets or others) into the project you just created
