Hello,

I have the same issue, did you manage to find a solution?

Thank you

I have the same issue

I did some digging and it seems that this is related to this bit of the code https://github.com/fluttercommunity/flutter_launcher_icons/blob/master/lib/android.dart#L309 basically int.parse(minSdk) is called with an empty string.
I assume this happens when your build.gradle file contains the following instead of a static value for the minVersion.

  defaultConfig {
        applicationId "com.grassecon.org.my_sarafu"
        minSdkVersion flutter.minSdkVersion
        targetSdkVersion flutter.targetSdkVersion
        versionCode flutterVersionCode.toInteger()
        versionName flutterVersionName
    }

As a quick hack you can change the following line https://github.com/fluttercommunity/flutter_launcher_icons/blob/master/lib/android.dart#L309

- return int.parse(minSdk);
+ return minSdk.isNotEmpty ? int.parse(minSdk) : 0;

This solved the problem thanks

edit the file android/app/build.gradle and chnage the params like below

 minSdkVersion 21
 targetSdkVersion 29

after the change run the below commands in terminal

 flutter pub get
 flutter pub run flutter_launcher_icons:main

after generating the icons successfully, change back the edited above lines like to their original form like below

minSdkVersion flutter.minSdkVersion
targetSdkVersion flutter.targetSdkVersion

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.

this worked for me, but I did not change back the syntax as you showed in the last step, will that be a problem?
