maybeOf static method

ValueListenable<SelectableRegionSelectionStatus>? maybeOf(
  1. BuildContext context
)

The closest instance of this class that encloses the given context.

If there is no enclosing SelectableRegion or SelectionArea widget, then null is returned.

Calling this method will create a dependency on the closest SelectableRegionSelectionStatusScope in the context, if there is one.

Implementation

static ValueListenable<SelectableRegionSelectionStatus>? maybeOf(BuildContext context) {
  return context
      .dependOnInheritedWidgetOfExactType<SelectableRegionSelectionStatusScope>()
      ?.selectionStatusNotifier;
}
