appbar_elevation

A Flutter Widget for an AppBar that is initially flush with the body and elevated when scrolled.

appbar_elevation-1

Usage

Use the ScrollActivatedAppBarElevation widget to wrap a Scaffold that contains
a Scrollable view (e.g. ListView, CustomScrollView). The widget uses a
NotificationListener to detect the scroll position and provides an
appBarElevation value to be used.

Example

@override
Widget build(BuildContext context) {
  return ScrollActivatedAppBarElevation(
    builder: (BuildContext context, double appBarElevation) {
      return Scaffold(
        appBar: AppBar(
          elevation: appBarElevation,
        ),
        body: ListView(
          children: [
            // ...
          ],
        ),
      );
    },
  );
}
