FMultiValueControl<T> class sealed

A FMultiValueControl defines how a FMultiValueNotifier is controlled.

A Control defines how a widget's state is managed:

• Managed: The widget manages its own controller. Pass configuration parameters directly or provide an external controller for programmatic access.

// Let widget create controller with configuration
FPopover(control: .managed(motion: myMotion, onChange: print));

// Or provide your own controller
FPopover(control: .managed(controller: _myController));

• Lifted: The parent owns the state. Pass the current value and an onChange callback. Useful for unidirectional data flow or integrating with external state management.

FPopover(
  control: .lifted(
    shown: _shown,
    onChange: (shown) => setState(() => _shown = shown),
  ),
)
