Flutter 3 - Stop Propagation When Tapping On Widget - flutter

Question

I have a TextField widget inside a Container and want to be able to tap on the TextField without the tap propagating to the parent (the Container). I also want to unfocus the TextField when tapping outside it. To achieve that I have wrapped the Container with an AbsorbPointer widget inside a GestureDetector. The problem is that this makes all taps go to the Container and I lose the ability to interact with the TextField.
How to stop event propagation from the TextField to the Container?
Edit: Futter docs says that TextField widget has a function for tapping outside:
onTapOutside → TapRegionCallback?
Called for each tap that occurs outside of the TextFieldTapRegion group when the text field is focused.
This property does not show among the available properties on the TextField in my app; Flutter 3.3.10 • channel stable
Code looks something like this:
class Filters extends StatelessWidget {
const Filters({super.key});
#override
Widget build(BuildContext context) {
return Container(
margin: const EdgeInsets.symmetric(horizontal: 12),
child: OutlinedButton.icon(
.
.
onPressed: () => {
showDialog(
context: context,
builder: (_) {
return Dialog(
child: SingleChildScrollView(
child: GestureDetector(
onTap: () => log("parent"),
child: AbsorbPointer(
child: Container(
.
.
child: Column(
children: [
.
.
TextField(
controller: textEditingController,
focusNode: focusNode,
onTap: () {
log("textField..............");
},
.
.
),
],
),
),
),
),
),
);
},
),
},
),
);
}
}
