SExpandableHandles class

A widget that displays an animated arrow icon for expandable menus.

The SExpandableHandles widget can operate in two modes:

Standalone Mode (Simple): When expandsRight and expandsDown are not provided, the widget manages its own internal expansion state. Simply provide onTap callback and the widget will automatically animate between states when tapped or when triggerOnTap changes.

SExpandableHandles(
  width: 70,
  height: 70,
  iconColor: Colors.white,
  onTap: () => print('Tapped!'),
)

Controlled Mode (Advanced): When expandsRight or expandsDown is provided, you control the expansion state via isExpanded. This is useful when the handle needs to reflect the state of an external expandable menu.

SExpandableHandles(
  width: 70,
  height: 70,
  iconColor: Colors.white,
  isExpanded: _isMenuExpanded,
  expandsRight: true,
  onTap: () => setState(() => _isMenuExpanded = !_isMenuExpanded),
)
