Flutter Launcher Icons has been designed to help quickly generate launcher icons for both Android and iOS: https://pub.dartlang.org/packages/flutter_launcher_icons
- Add the package to your pubspec.yaml file (within your Flutter project) to use it
- Within pubspec.yaml file specify the path of the icon you wish to use for the app and then choose whether you want to use the icon for the iOS app, Android app or both.
- Run the package
- Voila! The default launcher icons have now been replaced with your custom icon
I’m hoping to add a video to the GitHub README to demonstrate it
Video showing how to run the tool can be found here.
If anyone wants to suggest improvements / report bugs, please add it as an issue on the GitHub project.
Update: As of Wednesday 24th January 2018, you should be able to create new icons without overriding the old existing launcher icons in your Flutter project.
Update 2: As of v0.4.0 (8th June 2018) you can specify one image for your Android icon and a separate image for your iOS icon.
Update 3: As of v0.5.2 (20th June 2018) you can now add adaptive launcher icons for the Android app of your Flutter project
