In this tutorial, we will get introduced to Scaffold class, and how to use it to display a Scaffold layout in our Application. A Scaffold assumes that it is always the height of the device, so when calculating the contentBottom in order to avoid the keyboard, it doesn't include its own offset from the bottom of the screen, resulting in blank space between the keyboard and the body. I only got this when, for example, I wrap the index of page 2 in materialApp. Here is an example which replaces the default icons. Flutter Scaffold is used to display a basic material design layout that contains application bar, body, bottom navigation bar, bottom sheet, drawer, floating action button, persistent footer buttons, etc. I am trying to go to the next page using Navigator.push and at the same time change only the body on the page. Just change it in MaterialApp Widget inside of your main.dart (main file). I feel it would be cleaner (and easier to animate) if we could switch pages by using a Navigator. Flutter has predefined way to change background color of scaffold across app. Constructors of Scaffold() widget: Scaffold(,),Įxample of Scaffold widget: import 'package:flutter/material.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.

Define our entry point Let’s start by opening the main.dart file that is located under the lib/ directory. You can easily implement functional widgets like AppBar, FloatingActionButton, ButtonNavigationBar, Drawer, and many more widgets on the app using the Scaffold widget. description of static method ScaffoldState of ( BuildContext context ) Finds the ScaffoldState from the closest instance of this class that encloses the given context. The body is a Text placed in a Center in order to center the text within the Scaffold. In the body section, you should see the text Flutter Drawer Demo in the center of the screen. You should see an AppBar with the title Flutter Drawer Demo. Paste the code below into your code editor and run the app. The Scaffold widget is the base of the screen for a single page.
