BackdropToggleButton class

An animated button with backdrop related functionality.

It can be used to trigger the backdrop functionality of BackdropScaffold.

This button is implicitly used within BackdropAppBar. This button can also be passed to the BackdropAppBar.actions.

When being pressed, BackdropToggleButton looks for a Backdrop instance above it in the widget tree and toggles its opening/closing.

Example:

Widget build(BuildContext context) {
  return MaterialApp(
    title: 'Backdrop Demo',
    home: BackdropScaffold(
      ...
      actions: <Widget>[
        BackdropToggleButton(
          icon: AnimatedIcons.list_view,
        ),
      ],
    ),
  );
}
