Issue Description:
When using the AnimationController in Flutter, there is an issue where calling AnimationController.forward() after the controller has been disposed results in the following error:
Solution
Summary of Changes:
To address this issue, I have added a check for the "mounted" property before calling AnimationController.forward(). This ensures that the animation controller is not used after it has been disposed, preventing the error mentioned above.
Code Changes
Context
This change is essential to prevent the usage of the AnimationController after it has been disposed. The mounted property is a reliable way to determine if the widget is still part of the widget tree, and thus, it's safe to call AnimationController.forward().
Testing
I have added relevant tests to ensure that the issue is resolved and that the animation controller is only forwarded when the widget is still mounted.
Reviewer Notes
