ControlBuilderGroup({Key? key, required List controls, required ControlWidgetBuilder<List?> builder, bool passControls = false}): Builds Widget every time when data in controls are changed. controls - List of objects that will notifies Widget to rebuild. Supports ActionControl, FieldControl, StateControl, ValueListenable and Listenable. builder - Widget builder, passes value as List of values from given controls. passControls - Passes controls to builder instead of 'values'.
