Replacing app launcher icon in flutter with new icon

Question

I was looking for changing the app icon of my current app. I cane around the package name flutter_launcher_icons.

I also found I can do by putting an image in mipmap-xxxhdpi in android/app/res folder. And it works.

So my question is why we need additional package(flutter_launcher_icons) for this.

Answer 1

When you use the package flutter_launcher_icons it will automatically generate different icon sizes for the app which is better than just putting an image in mipmap-xxxhdpi in android/app/res.

Example, if you add flutter_launcher_icons to the pubspec.yaml:

dev_dependencies: 
  flutter_launcher_icons: "^0.7.3"

flutter_icons:
  android: "launcher_icon" 
  ios: true
  image_path: "assets/icon/icon.png"

Then execute the following:

flutter pub get
flutter pub run flutter_launcher_icons:main

It will generate all the icons under different sizes in the res folder for android and Assets.xcassets for ios.
