![]() ![]() Here is an example which replaces the default icons. / This Widget is the main application widget.To customise the leading icon, you may want to mimic the functionality of the AppBar widget, which properly handles showing a back button, drawer icon, or close icon, depending on the current context. In this example, we are going to see a Scaffold widget with an AppBar, BottomAppBar, FloatingActionButton, floatingActionButtonLocation, and drawer properties. connectionState. connectionState.none - In this state future is null 2. Let us see the example where we have tried to use most of the Scaffold properties to understand this widget quickly and easily. In future builder, it calls the future function to wait for the result, and as soon as it produces the result it calls the builder function where we build the widget. If we want to learn it in more detail, refer to the flutter documentation here. Its main purpose is to get familiar with different properties and their usage in Flutter application. That's all about the Scaffold's various properties that give us an overview of the Scaffold widget. To open the drawer, use the ScaffoldState.openDrawer function. Swipes in from either left-to-right ( TextDirection.ltr) or right-to-left ( TextDirection.rtl) Typically a Drawer. It contains many predefined constants, such as centerDocked, centerFloat, endDocked, endFloat, etc. A panel displayed to the side of the body, often hidden on mobile devices. It is used to determine the position of the floatingActionButton. floatingActionButtonLocation: By default, it is positioned at the bottom right corner of the screen. The bottom property defines the onscreen keyboard height.ġ1. resizeToAvoidBottomInset: If it is true, the body and the Scaffold's floating widgets should adjust their size themselves to avoid the onscreen keyboard. It can be swiped right to left or left to right.ġ0. endDrawer: It is similar to a drawer property, but they are displayed at the right side of the screen by default. We had also used onTap(int itemIndex) function to perform an action when we tapped on the items, which works according to their index position.ĩ. It is quick enough to create a general-purpose mobile. The BottomNavigationBarItems widget is used to add items in the bar containing text and icon as its child property. The Scaffold is a widget in Flutter used to implements the basic material design visual layout structure. The fixedColor property is used for the color of the active icon. In the above code, we have used the BottomNavigationBar widget to display the menu bar. ![]() See the below code:īottomNavigationBar: BottomNavigationBar( It uses the FloatingActionButton widget properties using Scaffold.floatingActionButton.

In the ListView widget, we have divided the panel into two parts, Header and Menu. The widget in the body of the scaffold is positioned at the top-left of the available space between the app bar and the bottom of the scaffold. ![]() To create a local project with this code sample, run: flutter create .1 mysample. Typical usage of the Scaffold.of function is to call it from within the build method of a child of a Scaffold. We have also used some other widgets to make it attractive. This method can be expensive (it walks the element tree). In the above code, we use the drawer property of Scaffold for creating a drawer. ![]()
