Flutter APK Errors while build apk command running?

I have a flutter app and its working fine in debug mode but when i run flutter build apk command for android apk it shows the following error. The error is cannot run with sound null safety. Error:

 C:\Users\RAILO\flutter\bin\flutter.bat --no-color build apk

 Building with sound null safety 

Running Gradle task 'assembleRelease'...                        
Error: Cannot run with sound null safety, because the following dependencies
don't support null safety:

 - package:flutter_swiper
 - package:flutter_page_indicator
 - package:transformer_page_view

For solutions, see https://dart.dev/go/unsound-null-safety


FAILURE: Build failed with an exception.
