Flutter AppBar Widget
The toolbar and other frequently used action buttons are located in the AppBar Widget, which is typically at the very top (or very bottom) of the program. Since a widget or collection of widgets constitutes every part of a flutter program. Flutter also has an AppBar class or widget that provides the same functionality by default.
Based on Material Design and using mobile application, the AppBar widget makes use of data offered by classes like MediaQuery and Scaffold to determine the optimal placement of the AppBar’s content. The AppBar class is highly customizable and adaptable, however, there is another widget called SliverAppBar that may be used to make the app bar scrollable. Another option is to design our app bar from the ground up.
What is Flutter – AppBar Widget
The Scaffold widget serves as the primary framework for a Flutter app, and an Flutter AppBar Widget is a horizontal bar that is usually positioned at the top. A title, a leading icon (like a menu or back button), and action icons (like search or settings) are all possible components. For a full and seamless user interface, use the AppBar in duo with the Scaffold.
Features of the Appbar Widget
Actions: When the AppBar is a row, this property accepts an argument that specifies which widgets should be shown after the title.
Title: Typically, the main widget is passed as an argument to this property so it may be displayed in the AppBar.
BackgroundColor: The background color of the Appbar can be customized using this parameter.
Elevation: The z-coordinate at which this app bar is placed relative to its parent can be set using this attribute.
Shape: The Appbar’s form and shadow are controlled by this feature.Â
