HoverBuilder class

A widget that detects mouse hover events and notifies its child. This widget is useful when you want to change the appearance of a widget when the mouse hovers over it.

Example: HoverBuilder( builder: (context, hovering, child) { return AnimatedContainer( duration: const Duration(milliseconds: 200), width: 100, height: 100, color: hovering ? Colors.orange : Colors.red, alignment: Alignment.center, child: child, ); }, child: const Text('Hover Me'), ),

Properties

builder HoverWidgetBuilder
Builder that builds the child. This builder will be called whenever the hover state changes. The hovering parameter indicates whether the widget is currently being hovered or not.
final

final
enabled bool
Whether the hover effect is enabled or not. If set to false, the cursor will be MouseCursor.defer and the hover effect will not be applied.
final
hashCode int
The hash code for this object.
