I am getting the same issue

[priyankabambharoliya-official]

I found quick fix, here it is #351 (comment)

[LahaLuhem]

I have an easy fix:

1. Change Line 308 in Dart Packages/flutter_launcher_icons/android.dart:
   • previous: final String minSdk = line.replaceAll(RegExp(r'[^\d]'), '');
   • change to: final String minSdk = "21";
2. Recompile the packages by running flutter clean, followed by flutter pub get again
3. Run generating procedure again by flutter pub run flutter_launcher_icons:main

It just skips the parsing of the manifest file directly to get the minSDK version line.

thank you, it works!
