Expander class

Inheritance

Constructors

Expander({required AnimationController controller, required List<Widget> triggerWidgets, VoidCallback? onHide, VoidCallback? onShow, Duration? arrowRotationDuration, bool showRotatingArrow = true, bool rotateArrow = true, Color rotatingArrowColor = Colors.green, double rotatingArrowSize = 20})
controller Controls which expander triggers which expandable. Must not be null and should be the same as its Expandable's controller
factory
Expander.builder({required Widget builder(BuildContext context, Widget arrow), required AnimationController controller, VoidCallback? onHide, VoidCallback? onShow, Duration? arrowRotationDuration, bool rotateArrow = true, Color rotatingArrowColor = Colors.green, double rotatingArrowSize = 20})
Provides a BuildContext and the rotating arrow so you can place it wherever you need to
