[FIXED] Version code 1 has already been used. Try another version code

Issue

I am uploading new app bundle to play console and it is saying after uploading Version code 1 has already been used. Try another version code.

I have changed version number in pubspec.yaml from version number: 1.0.0+1 to 2.0.0+1 even though it is saying the same error

Solution

You have to increment the +1, it should be +2 to indicate build number
