SearchAnchor tries to use its controller after being disposed #155180
Description
Steps to reproduce
- Open the drawer.
- Click on the search icon. The search view appears.
- Double click outside of the search view AND outside the drawer as well.
Expected results
The first click should close the search view, while the second should close the drawer. This should happen without any errors.
Actual results
The following exception is thrown:
════════ Exception caught by widgets library ═══════════════════════════════════
The following assertion was thrown building RawGestureDetector(state: RawGestureDetectorState#118c4(gestures: [tap, long press, tap and pan], excludeFromSemantics: true, behavior: translucent)):
A SearchController was used after being disposed.
Once you have called dispose() on a SearchController, it can no longer be used.
The relevant error-causing widget was:
MaterialApp MaterialApp:file:///home/user/project/lib/main.dart:12:18
