31.15 Flutter App Icon

20240122

The flutter_launcher_icons package will do the hard work to generate icons for the different platforms (excluding Linux). Essentially it modifies the various platform files with a newly supplied png file as the icon. Below is a record of what it changes, noting that the package is currently 9 months since it was last updated and some of these may not reflect the latest practise. It’s a great start and generally works.

To use this package add the following to pubspec.yaml:

dev_dependencies:
  flutter_launcher_icons: ^0.13.1

And then

flutter_launcher_icons:
  android: true
  ios: true
  image_path: "assets/icons/icon.png"
  min_sdk_android: 21
  remove_alpha_ios: true
  web:
    generate: true
    image_path: "assets/icons/icon.png"
  windows:
    generate: true
    image_path: "assets/icons/icon.png"
    icon_size: 48
  macos:
    generate: true
    image_path: "assets/icons/icon.png"

Then:

flutter pub get
dart run flutter_launcher_icons
