I encounter an error after a flutter update. AssetManifest imported from two libraries

I have an app that I created a year ago that worked great. Lately I opened my code and Flutter suggested I do an update. After the update it no longer works. the error encountered indicates that I imported AssetManifest from 'package:flutter/src/services/asset_manifest.dart' and from 'package:google_fonts/src/asset_manifest.dart'.

As mentioned here, version 4.0.1 of the google_fonts fixes this issue. Therefore, upgrading to at least version 4.0.1 should resolve your problem.
