Research direction
The issue names no files, tests, or entry points. Start by auditing stateful widgets for AnimationController, TextEditingController, ScrollController, StreamSubscription, ChangeNotifier listeners, and timers, then identify the project’s existing disposal patterns. Done means each resource is disposed or cancelled with its owning widget and the reported leaks are addressed.

Description
Root Cause:
Inconsistent and incomplete resource disposal patterns Impact:
- Memory leaks from undisposed controllers
- Performance degradation over time
- Potential crashes from accessing disposed resources
- Battery drain from active subscriptions
What happened?
- Missing dispose() methods in stateful widgets
- Controllers not properly disposed
- Stream subscriptions left active
- Timers continuing after widget disposal
- Animation controllers causing memory leaks
Examples of Resources to Dispose:
- AnimationController
- TextEditingController
- ScrollController
- StreamSubscription (e.g., network streams)
- ChangeNotifier listeners
- Any other objects that consume system resources or have active subscriptions.
