Flutter Launcher Icons #
A command-line tool which simplifies the task of updating your Flutter app's launcher icon.

:book: Guide #
1. Setup the config file
Add your Flutter Launcher Icons configuration to your
pubspec.yaml or create a new config file called
An example is shown below. More complex examples can be found in the example projects.
dev_dependencies: flutter_launcher_icons: "^0.8.0" flutter_icons: android: "launcher_icon" ios: true image_path: "assets/icon/icon.png"
If you name your configuration file something other than
pubspec.yaml you will need to specify
the name of the file when running the package.
flutter pub get flutter pub run flutter_launcher_icons:main -f <your config file name here>
Note: If you are not using the existing
pubspec.yaml ensure that your config file is located in the same directory as it.
2. Run the package
After setting up the configuration, all that is left to do is run the package.
flutter pub get flutter pub run flutter_launcher_icons:main
If you encounter any issues please report them here.
In the above configuration, the package is setup to replace the existing launcher icons in both the Android and iOS project with the icon located in the image path specified above and given the name "launcher_icon" in the Android project and "Example-Icon" in the iOS project.
🔍 Attributes #
Shown below is the full list of attributes which you can specify within your Flutter Launcher Icons configuration.
true: Override the default existing Flutter launcher icon for the platform specified
false: Ignore making launcher icons for this platform
icon/path/here.png: This will generate a new launcher icons for the platform with the name you specify, without removing the old default existing Flutter launcher icon.
image_path: The location of the icon image file which you want to use as the app launcher icon
image_path_android: The location of the icon image file specific for Android platform (optional - if not defined then the image_path is used)
image_path_ios: The location of the icon image file specific for iOS platform (optional - if not defined then the image_path is used)
Note: iOS icons should fill the entire image and not contain transparent borders.
The next two attributes are only used when generating Android launcher icon
adaptive_icon_background: The color (E.g.
"#ffffff") or image asset (E.g.
"assets/images/christmas-background.png") which will be used to fill out the background of the adaptive icon.
adaptive_icon_foreground: The image asset which will be used for the icon foreground of the adaptive icon
Flavor support #
Create a Flutter Launcher Icons configuration file for your flavor. The config file is called
flutter_launcher_icons-<flavor>.yaml by replacing
<flavor> by the name of your desired flavor.
The configuration file format is the same.
An example project with flavor support enabled has been added to the examples.
❓ Troubleshooting #
Listed a couple common issues with solutions for them
Generated icon color is different from the original icon
Caused by an update to the image dependency which is used by Flutter Launcher Icons.
Use #AARRGGBB for colors instead of ##AABBGGRR, to be compatible with Flutter image class.
Image foreground is too big / too small
For best results try and use a foreground image which has padding much like the one in the example.
👀 Example #
Note: This is showing a very old version (v0.0.5)
