i’m trying to use flutter_launcher_icons 0.14.1 to create launcher icon for my flutter app. i followed the instructions in the pubdev of it
and when i ran dart run flutter_launcher_icons, this is the output

Built flutter_launcher_icons:flutter_launcher_icons.

i’ve tried flutter clean -> flutter pub get -> dart run flutter_launcher_icons -> run the flutter app, the error is still showing and the launcher icon is the android logo. i’ve tried to chatgpt and claude this but they can’t seem to figure it out.
