Using flutter_launcher_icons.yaml

This is the simplest way. Add this tool to your pubspec.yaml file.

  dependencies:
    flutter_launcher_icons: ^0.7.2
  flutter_icons:
    android: true
    ios: true
    image_path: "assets/images/favicon.avif"

Configure as needed, then run flutter pub get. Next, execute flutter pub run flutter_launcher_icons:main. If using a different config file, add -f {file name}.

Using Android Studio’s Asset Studio

For Android, right-click the android folder. Select New > Image Asset. Customize your icon with this feature. It supports various icon types and sizes.
