![]() ![]() The function is on each page, and it has the same name on each page. It is quick enough to create a general-purpose mobile. When creating some widgets, such as a snackbar, you have to grab the nearest Scaffold context so that Flutter knows how to paint the snackbar, since Scaffold is the widget that actually gives us access to displaying snackbars. You have to pass the widget and it will be displayed on the screen. body - Widget This is the main content property on Scaffold. ![]() Scaffold( backgroundColor: Colors.blue, //set background color of scaffold to blue ) 3. I have a button on the appbar, and I want it to call a function from whichever page is open. The Scaffold is a widget in Flutter used to implements the basic material design visual layout structure. An application has many screens for product feature listing and includes different screens to navigates. The Gotcha With the scaffold, Flutter does give us a nice way to solve following problem. backgroundColor - Color This property on Scaffold is used to change the background color of the Scaffold screen. Here is an example which replaces the default icons. I have a class for each 'page' of my app, and they all share the same appbar, which is a class of its own. Each of those pages uses MyAppBar, and each of those pages has _myFunction().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 my shortened code below, you see the shared MyAppBar, and you see 2 pages. Then add the color parameter to the BackButton as below: AppBar ( leading: const BackButton ( color: Colors.black, // Change the color here ), centerTitle: true, ) Share. The function is on each page, and it has the same name on each page. In the AppBar, add the leading parameter and assign the BackButton widget. This should be used for most simple use cases. Scaffold ( body: Column ( children: //all the children widgets that you need, ), ), Share. 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 implement TabBar in your Flutter app, complete the following steps: Wrap the Scaffold widget inside the DefaultTabController.I have a button on the appbar, and I want it to call a function from whichever page is open. you need to give body a Column widget as a child and then you can use as many children as you want. To create a local project with this code sample, run: flutter create -samplematerial.Scaffold.1 mysample. I have a class for each "page" of my app, and they all share the same appbar, which is a class of its own. ![]()
