Flutter error when building for Android: Invalid <color> for given resource value

After changing the app icon with flutter_launcher_icons, I started having this issue after running flutter run and flutter build apk:

flutter build apk -debug

/Users/pitol/.gradle/caches/transforms-3/dfcbd5820ba82f60df3a20d93f4b43e6/transformed/core-1.8.0/res/values/values.xml:5:4: Invalid <color> for given resource value.

Tried to run flutter doctor -v, solved all the dependencies, updated android studio, updated Java and still get this error when I try to build android app (doctor -v command shows no error);

Already tried on Mac and Windows, and it shows the same error;

I also tried to create a new flutter project and builded succesfully, so the issue is in the project, not in the framework;

Solution

Step 1: Remove all the .png files generated by flutter_launcher_icons in the project;

Step 2: Remove the flutter_launcher_icon implementation from pubspec.yaml;

Step 3: Delete the .../android/app/src/main/res/values/colors.xml file;

Step 4: Delete the .../android/app/src/main/res/mipmap-anydpi-v26/ic_launcher.xml file;

Step 5: Run flutter clean;

Step 6: Run flutter pub get;

Step 7: Make sure there are no dependencies for the platform desired by running flutter doctor -v;

Step 8: Try to run or build the APK (flutter run or flutter build apk -debug);

Step 9: If the app builds appropriately, you can try to import the flutter_launcher_icons again and follow their readme steps. But this time, keep the launcher icon file the same name as it is on their pubspec example;

Step 10: Make sure the .xml files you deleted in previous steps weren't created again and run/build the app;
