flutter launcher icon does not change

Question

I have downloaded a sample app project and now I want to change its icon. I have installed the flutter_launcher_icons package. I added this to pubspec.yaml file

dev_dependencies:
  flutter_test:
    sdk: flutter
  flutter_launcher_icons: "^0.11.0"

flutter_icons:
  android: true
  ios: true
  image_path: "assets/icon/logo.png"
  remove_alpha_ios: true
  min_sdk_android: 21

Run the following commands

flutter pub get
flutter pub run flutter_launcher_icons

It gives me success message

 ════════════════════════════════════════════
     FLUTTER LAUNCHER ICONS (v0.11.0)

But When I install the app all I see is the old icon. What might be the cause of the problem?

Answer 1

change your above code to

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

as you did before run the commands

flutter pub get  
flutter pub run flutter_launcher_icons:main

and then remove your application from android device/emulator. run your application again and the icon will be changed..
