I use the searchField, judging by the documentation, there should be an onTab field in the searcField widget, but apparently the library has been updated and there is no such function anymore, since I need to trigger an event in the block when clicking on the field, I decided to wrap the widget in inkwell, but when clicked, nothing works and the event does not called
BlocBuilder<FillprofileBloc, FillprofileState>(
builder: (context, state) {
return InkWell(
focusColor: Colors.transparent,
onTap: () {
_bloc.add(OnCitySearchTabEvent());
},
child: SearchField(
searchInputDecoration: InputDecoration(
There is a workaround with GestureDetector.
GestureDetector(
behavior: HitTestBehavior.translucent,
onPanDown: (_) {
debugPrint("pan down");
},
child: SearchField(),
),
You can use onTap param of TextField itself here. Or wrap your TextField with IgnorePointer to use InkWell

does anyone know how to make a focus node loose focus when clicking outside the focus node ? Basically, I got something like this:
InkWell(
focusNode: focusNode,
child: ...,
onTap: () {
...
},
),
But the focusNode doesn't lose his focus when I'm clicking outside the InkWell widget.
I have tried to use the FocusTrap widget, which seems to do exactly that. But I can't get a focusScopeNode from my focusNode, all I get is null (I don't really understand how focusScopeNode works)
Note that I can't do something hacky like
GestureDetector(
onTap: () {
Focus.of(context).unfocus();
},
child: Scaffold(
// ...
),
);
Because I'm in a package context
Does anyone know how to do this ?
I have a TextField inside of an InkWell with an onLongPress() callback. The problem is, despite the fact that even when long pressing on the TextField, I see the ripple effect on InkWell, but the onLongPress() does not run after the long press time passes. It only gets me into editing Text. When pressing on the bottom side of the Card, everything runs fine.
In short: On tap I want to get into TextField editing. On long press I want to trigger the onLongPress(), not the TextField, even if I am pressing on it.
How do I do this? Thank you.
InkWell(
onLongPress: () {
// do stuff
}
child: ListTile(
title: TextField(),
),
),
You can use the AbsorbPointer widget to ignore the TextField gesture recognizer:
InkWell(
onLongPress: () {
print('onLongPress');
},
child: AbsorbPointer(
child: ListTile(
title: TextField(),
),
),
)
To still enabling the editing of TextField when single tapping on it, you can use FocusNode like this:
InkWell(
onLongPress: () {
print('onLongPress');
},
onTap: () => node.requestFocus(),
child: AbsorbPointer(
child: ListTile(
title: TextField(
focusNode: node,
controller: textController,
),
),
),
)
#Bach 's answer helped me to find a solution. Thank you!
InkWell(
onLongPress: () {
// do stuff
},
child: ListTile(
title: GestureDetector(
onTap: () => FocusScope.of(context).requestFocus(_focusNode),
child: AbsorbPointer(
child: TextField(
focusNode: _focusNode,
),
),
),
),
The only problem is now that I started messing with focusNode, multiple input fiels are focusing at the same time. But that is a whole other story ;)
UPD: Just realised, that I can't move text cursor this way. So not useful.
It seems that IntrinsicWidth widget can find the right balance between long press and text editing.
The rationale behind is that IntrinsicWidth will let the TextField shrink to its minimum width, therefore avoiding a gesture collision with the InkWell
So your solution can be like this:
InkWell(
onLongPress: () {
// do stuff
}
child: ListTile(
child: IntrinsicWidth(
title: TextField(
//remember to make some hints here
//because with intrinsicwidth if your textfield is empty it might disappear
),
),
),
),
Flutter:
I would like to open a Form after a RaisedButton is pressed. How do I have to compose the onPressed function of the RaisedButton to achieve this?
Thanks for your support.
As you have not mentioned more detail, i hope you need something to show or input. You can use showBottomSheet to fulfill this like this :
RaisedButton(
onPressed: () {
showModalBottomSheet(
context: context,
builder: (BuildContext bc) {
return Container(
child: Text('Implement your form here')
);
});
},
child: Text('BottomSheet Demo')
)
In this part of code only doSthElse() is being called.
GestureDetector(
onTap: doSth,
child: FloatingActionButton(
onPressed: doSthElse,
)
)
If I set null instead of doSthElse, then doSth is called when onTap occurs.
Is there any way to call both methods on the same tap action?
Thanks guys, I figured it out. I merged #Benjamin and #Locked answers and got this:
GestureDetector(
onTap: () {
doSth();
widget.button.onPressed();
},
child: AbsorbPointer(
child: widget.button,
absorbing: true,
),
)
widget is StatefulWidget and code above is in its state build method.
I'm trying to make a modal bottom sheet with ListTiles that contain a Checkbox as the leading widget. However, the Checkbox will receive tap event instead of the ListTile, now showing the ink ripple effect for the tile and making me implement two onTap/onChanged callbacks.
I have tried not implementing the Checkbox's onChanged callback and wrapping it around an AbsorbPointer widget, however in these two cases the ListTile would also not get the tap event.
return ListTile(
onTap: onTap,
title: Text("Show expired schedules"),
leading: Checkbox(value: snapshot.data, onChanged: (_) => onTap()),
);
I would like to somehow make the Checkbox not tappable, but have the ListTile still receive the tap event. Kind of like AbsorbPointer, except skipping one Widget, not absorbing the tap event entirely.
Wrap your Checkbox widget inside IgnorePointer widget and it should work:
return ListTile(
onTap: onTap,
title: Text("Show expired schedules"),
leading: IgnorePointer(child: Checkbox(value: snapshot.data, onChanged: (_) => onTap())),
);
You can do that using AbsorbPointer too
return ListTile(
onTap: onTap,
title: Text("Show expired schedules"),
leading: AbsorbPointer(
absorbing: _condition, // bool value, true makes it absorb touch event on CheckBox still making ListTile tappable.
child: Checkbox(value: snapshot.data, onChanged: (_) => onTap()),
),
);
