Nested MenuAnchors throw 'A TextEditingController was used after being disposed' when MenuItem is selected #139266
Description
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
- Created nested MenuAnchors
- Select a MenuItem from the child MenuAnchor
- All MenuAnchors are closed, and error is thrown, and the onSelected method of the MenuItem is not called
Expected results
- The onSelected method of the selected MenuItem should be called
- No error should be thrown
- Only the Menu that contains the MenuItem should be closed (or this behaviour should be configurable)
Actual results
- All MenuAnchors are closed
- an error is thrown: 'A TextEditingController was used after being disposed.'
- the onSelected method of the MenuItem is not called

(it) =>
DropdownMenuEntry(
value: it,
label: it,
),
)
.toList(),
onSelected: (selection) {
// this is never called
print("selected: $selection");
},
);
