Is there an existing issue for this?

• I have searched the existing issues
• I have read the guide to filing a bug

Steps to reproduce

Have any package that use buildTransations (like GetX for example)
Have flutter after aaaea51
flutter run

Expected results

Should compile and run

Actual results

Won't compile no more

Problem source

The commit aaaea51 introduced an unnecessary breaking change in the buildTransitions function signature. This breaking share will break any lib, (like here the very popular GetX) in all versions that use the function because of the unnecessary breaking change.

Could that added parameter be made optional so apps will compile again without having to modify all the packages that are using buildTransitions?
