pub finished with exit code 255

Solution

I faced similar issue . I resolved it by changing following properties in android/app/build.gradle

minSdkVersion flutter.minSdkVersion
targetSdkVersion flutter.targetSdkVersion

To

minSdkVersion 26
targetSdkVersion 32

Not sure what the issue is, I assume you double checked the path to your icon? Maybe try running it with dart pub run instead of flutter pub run will change the result
