The behavior of Dismissible with TextFormFields is different for Android and iOS #142447
Description
Steps to reproduce
- Run the code sample on Android and iOS.
- Dismiss an item with the red SizedBox and the TextFormField part.
Expected results
The behavior should be the same on iOS and Android. In my opinion, it should on both platforms be possible to dismiss by sliding the TextFormField.
If the TextField takes up the entire Dismissible, then it will handle the gesture.
This is also not true for iOS.
Actual results
On Android you can dismiss an item by touching the red SizedBox part but also the TextFormField part.
On iOS you can dismiss an item only by touching the red SizedBox part but not the TextFormField part.

List<int> items = List<int>.generate(10, (index) => index);
@override
Widget build(BuildContext context) {
return Scaffold(
body: ListView.builder(
itemCount: items.length,
itemBuilder: (_, index) => Dismissible(
key: ValueKey<int>(items[index]),
onDismissed: (DismissDirection direction) {
setState(() {
items.removeAt(index);
});
},

The issue has something to do with the field implementing gestures for the text selection.
If you replace the field with a Gesture detector and pass
onHorizontalDragUpdateyou get the same behavior you get on iOS (but you get it on both platforms). (It doesn't happen if you define only onTap)I believe that the field widget implements some platform-specific logic that defines (only for iOS) the dragging behavior for the RawGestureDetector underneath.
My results by running gesture arena:
Android
iOS

Thanks for the report. I was able to see the same behavior as observed on both platforms. The same is noticed using the official code sample (by replacing
TextwithTextField).I looked at native iOS app (Reminders) and observed that the swiping from center area which is clickable, is possible.

Updated the code from above link and running on both platform still gives the same behavior as reported.
stable, master flutter doctor -v
