Add a controller to SelectionArea #127025
Description
Is there an existing issue for this?
- I have searched the existing issues
- I have read the guide to filing a bug
Use case
I want to request a controller for the SelectionArea Widget.
Right now I find it almost impossible to select al items under a SelectionArea by default programmatically, the only way is after a user input the selectableRegionState is created.
This is a current implementation
SelectionArea(
onSelectionChanged: (value) => print(value?.plainText),
contextMenuBuilder: (context, selectableRegionState) {
this.selectableRegionState = selectableRegionState; // <- This is when i initialize the state
return Text('....'); // your context menu
},
child: Stack(
alignment: Alignment.center,
children: ...state.result.map(TextQuad.new), // A widget with text's
),
),Proposal
SelectionArea(
controller: controller, // <- new
onSelectionChanged: (value) => print(value?.plainText),
child: Stack(
alignment: Alignment.center,
children: ...state.result.map(TextQuad.new), // A widget with text's
),
),And use it like:
controller.selectAll();
