I upgraded Flutter Version & I am getting this issue in my Flutter Projects
TypeScript

TL;DR
Issue: After upgrading Flutter version, getting unresolved reference errors for Registrar in FlutterWebAuth2Plugin.kt and deprecated API warnings in RazorpayDelegate.java.
Solution: Update the dependencies causing the issues, such as FlutterWebAuth2 and razorpay_flutter, to their latest versions compatible with the upgraded Flutter version. The errors should be resolved after updating the dependencies.
