SystemContextMenuController.show Deprecated
Summary
#
SystemContextMenuController.show is deprecated. The same functionality can be
achieved by passing the result of calling SystemContextMenu.getDefaultItems
to
SystemContextMenuController.showWithItems.
Background
#
The iOS-drawn SystemContextMenu feature was originally added without the
ability to control which items are shown in the menu. The platform would decide
which items to show based on the active TextInputConnection.
The problem with this approach is that an "Autofill" button is often shown, but Flutter does not have the ability to respond to this button. So in many cases, users see an "Autofill" button that does nothing when tapped, and Flutter app developers have no way to hide the button.
This problem is solved by introducing a new method,
SystemContextMenuController.showWithItems, which requires a list of items
to
be passed.
Developers that have no preference which items are shown can call the new method
SystemContextMenu.getDefaultItems to get the default items based on the given
EditableTextState. For example, if the EditableTextState
indicates that
there is nothing selected, then the Copy button won't be included, since it
requires a selection to copy.
Migration guide
#
Most users use the system context menu through the SystemContextMenu widget,
and in this case there will be no change required. The SystemContextMenu
widget automatically gets the default items under the hood.
No migration is needed:
class _MyWidgetState extends State<MyWidget> {
@override
Widget build(BuildContext context) {
TextField(
contextMenuBuilder: (BuildContext context, EditableTextState editableTextState) {
return SystemContextMenu.editableText(
editableTextState: editableTextState,
);
}
);
}
}
For advanced users that directly work with SystemContextMenuController,
migrate to the new method SystemContextMenuController.showWithItems. The
default can be obtained from SystemContextMenu.getDefaultItems as a list of
IOSSystemContextMenuItems, which can be converted to the format required by
showWithItems through IOSSystemContextMenuItem.getData.
Code before migration:
_controller.show(selectionRect);
Code after migration:
final List<IOSSystemContextMenuItem> defaultItems =
SystemContextMenu.getDefaultItems(editableTextState);
final WidgetsLocalizations localizations =
WidgetsLocalizations.of(context);
final List<IOSSystemContextMenuItemData> defaultItemDatas =
defaultItems
.map((IOSSystemContextMenuItem item) =>
item.getData(localizations))
.toList();
_controller.showWithItems(selectionRect, defaultItemDatas);
