I have successfully changed the App Icon for the App by replacing the file with the files I downloaded from here.

Its working fine in the Menu with logo and name as expected. but the icon is not changed in the Task Menu.enter image description here

And in the Menu its fine though.enter image description here

I replaced [mipmap-hdpi, mipmap-mdpi, mipmap-xhdpi, mipmap-xxhdpi, mipmap-xxxxhdpi] folders with new ones in the android->app->src->main->res path of my project.

Any help will be highly appreciated.


Solution 1: Sunil

Please check manifest file.

  <application
        android:name="io.flutter.app.FlutterApplication"
        android:label="flutter"
        android:icon="@mipmap/app_logo">

You have to change icon name here.

I had exactly the same issue. I rebooted my smartphone and it worked as it was suggested in related topics. After restart the icon is displayed as it should everywhere.
