android\app\src\main\res\mipmap-xxxhdpi\ic_launcher.png: AAPT: error: failed to read PNG signature: file does not start with PNG signature

Question

am using the package flutter_launcher_icons to generate launcher icons for my flutter app ,

using the method mentioned a the documentation I have added the file and mentioned it on my pubspec.yaml

flutter_icons:
  android: launcher_icon
  image_path: assets/images/launcher_icon.png
  ios: true
  remove_alpha_ios: true

and then called it using

flutter pub get
flutter pub run flutter_launcher_icons

all files are being generated without a problem but when I run

flutter build appbundle --release

am getting this error:

FAILURE: Build failed with an exception.
