Flutter appbundle version code error. Version code 20220304 has already been used. Try another version code

Question

I try build new release for google play, so I change version at file pubspec.yaml from 0.1.1+20220304 to 0.1.4+20220307, but after uploading, GPlay console return error: Version code 20220304 has already been used. Try another version code. I do not have hardcoded number 20220304 anywhere. I use app version straight from pubspec.yaml: version: 0.1.4+20220307 Why during build tools get old app version?

Answer 1

run flutter clean before building your apk/bundle

Answer 2

Just need to remove build folder from project root directory.
