flutter_launcher_icons not working (app launcher icon broken/crashed)

I'm struggling with changing App Launcher Icon using flutter_launcher_icons package, on my iPhone Simulator (iOS 14.4).

In my pubspec.yaml:

dev_dependencies:
  flutter_test:
    sdk: flutter
  flutter_launcher_icons: ^0.9.2

flutter_icons:
  #image_path_android: "assets/icon.png"
  image_path: "assets/icon.png"
  android: false
  ios: true

On VScode terminal (in my project root directory):

> flutter pub run flutter_launcher_icons:main
  ════════════════════════════════════════════
     FLUTTER LAUNCHER ICONS (v0.9.1)                               
  ════════════════════════════════════════════

But in the Simulator, app launcher icon is broken ('Runner' is the App):

enter image description here

In ~/ios/Runner/Assets.xcassets/AppIcon.appiconset/, I can see that the image files are correctly changed.

How can I fix this? Maybe it's not package problem, but iOS build problem??

Solution

  • Solved. The problem was that I accidentally deleted all files at 'Copy Bundle Resources'.
