It determines what each element on the screen of a flutter application should look like. Widgets are the basic building blocks of a Flutter application. Flutter applications by design are made up of various widgets which are either visible or invisible. What is a Flutter Widgetįlutter is an open-source framework developed by Google for building beautiful, natively compiled cross-platform applications from a single code base. We will also learn how to pad and decorate boxes in a Flutter application. In this article, while covering the box model, we will build a demo Flutter application with intermediate to advanced layout examples and demonstrate how to implement, set, and dynamically change the margins and padding of widgets. / This Widget is the main application widget.This article seeks to explain the difference between padding and margins in a Flutter application layout. In this example, we are going to see a Scaffold widget with an AppBar, BottomAppBar, FloatingActionButton, floatingActionButtonLocation, and drawer properties. Let us see the example where we have tried to use most of the Scaffold properties to understand this widget quickly and easily. 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. It contains many predefined constants, such as centerDocked, centerFloat, endDocked, endFloat, etc. 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. The BottomNavigationBarItems widget is used to add items in the bar containing text and icon as its child property. 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. While scrolling the page, its position cannot be changed. It is a circular icon button that floats over the content of a screen at a fixed place to promote a primary action in the application. floatingActionButton: It is a button displayed at the bottom right corner and floating above the body. Again, we have used ListTile to add the list items in the menu.Ĥ. The DrawerHeader property modifies the panel header that also contains an icon or details according to the application. In the ListView widget, we have divided the panel into two parts, Header and Menu. We have also used some other widgets to make it attractive. ![]() In the above code, we use the drawer property of Scaffold for creating a drawer. ![]()
