# auto_expanding_navigation_rail

An example project of how to add an "auto expanding" navigation rail.

## tldr;

Wrap a `NavigationRail` in a `MouseRegion`:

```dart

MouseRegion(

  onEnter: (_) => setState(() => expanded = true),

  onExit: (_) => setState(() => expanded = false),

  child: NavigationRail(

    destinations: [ ... ],

    selectedIndex: index,

    extended: expanded,

    onDestinationSelected: (i) => setState(() => index = i),

  ),

)

```
