Code Review
This pull request replaces CurvedAnimation with CurveTween in InteractiveViewer to address potential memory leaks and adds a regression test. The review feedback points out that listeners from previous animation objects must be explicitly removed before replacement to prevent accumulation on the controllers. Additionally, the feedback suggests using const CurveTween for performance optimization and tightening the test assertion to ensure that no CurvedAnimation instances are created during the operations.

LGTM 👍 . Thanks for cleaning this up. Indeed this mistake is easy to make if we are doing it ourselves in the framework code.
