A Flutter Widget for an AppBar that is initially flush with elevated when scrolled
appbar_elevation
A Flutter Widget for an AppBar that is initially flush with the body and elevated when scrolled.
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: [
// ...
],
),
);
},
);
}
