Is there a way to remove the drop shadow under the app bar (AppBar class) when using a Scaffold widget in Flutter?
4 Answers
Looking at the AppBar
constructor, there's an elevation
property that can be used to set the height of the app bar and hence the amount of shadow cast. Setting this to zero removes the drop shadow:
@override
Widget build(BuildContext context) {
return Scaffold(
appBar: AppBar(
title: const Text('My App Title'),
elevation: 0,
),
body: const Center(
child: Text('Hello World'),
),
);
}

If you want to remove the shadow of all app bars without repeating code, just add a AppBarTheme
property with elevation: 0
to your app theme (ThemeData
), inside your MaterialApp
widget:
// This code should be located inside your "MyApp" class, or equivalent (in main.dart by default)
return MaterialApp(
// App Theme:
theme: ThemeData(
// ••• ADD THIS: App Bar Theme: •••
appBarTheme: AppBarTheme(
elevation: 0, // This removes the shadow from all App Bars.
)
),
);

To remove appbar
drop down shadow set a AppBar constructor elevation: 0.0
The arguments primary, toolbarOpacity, bottomOpacity
and automaticallyImplyLeading must not be null. Additionally, if elevation is specified, it must be non-negative.
If backgroundColor, elevation
, shadowColor, brightness, iconTheme, actionsIconTheme, textTheme or centerTitle are null, then their AppBarTheme values will be used. If the corresponding AppBarTheme property is null, then the default specified in the property's documentation will be used.
appBar: AppBar(
title: Text('App Title'),
elevation: 0.0,
bottomOpacity: 0.0,
),
