Update the build function in _MyHomePageState so that it matches this code snippet. Now that we have functions to construct the content for the app, let’s update our Scaffold to use them to pull in the required content. Step 4: Modify the Build Function in _MyHomePageState to Use the Content Builder Functions Defined Trailing: const Icon(Icons.favorite_outline),Ĭhild: Text(cardData!), Insert the following functions into the _MyHomePageState class of your app.ĬardContent.map((cardData) => _buildCard(cardData)).toList(), It’s invoked for each property that we generated content for in Step 2 above. For any null property on the ButtonBar, the surrounding ButtonBarTheme's property will be used instead. The ButtonBar can be configured with a ButtonBarTheme. The _buildCard function is used by the _buildBody function to construct a single property card. For example, if the buttons overflow and ButtonBar.alignment was set to MainAxisAlignment.start, the buttons would align to the horizontal start of the button bar. The _buildBody function constructs the body with all the real estate property cards. The arrow indicates that it is a dropdown menu / list so that the user can select another item. The currently selected item will be displayed on the button along with an arrow. The user can select an item from a list of items. The _buildAppBar function constructs and returns the AppBar for our app. Flutter Dropdown Button Widget Dropdown button is a material widget that displays a dropdown list / menu in flutter. When you touch on the icon it will respond according to its functionality. I am showing examples for start and center. The alignment takes MainAxisAlignment class as a value that has constants like start, center, end, spaceEvenly, spaceBetween, spaceAround. alignment We will use this property to align the buttons in the button bar. In Step 3, we create functions within the _MyHomePageState class that builds the AppBar and the main body of the app. This is another type of button which is consisting of an icon than text. Let’s see some properties of flutter button bar with example. 'Beautiful home, recently refurbished with modern appliances.' To follow along with this tutorial, head over to īelow is what the final app will look like.Ĭlass MyApp extends StatelessWidget build(BuildContext context) 00 sqft' DartPad is a web-based editor where you can try out Flutter code without the need to install anything on your computer. Therefore, you can use DartPad to follow along. This demo app doesn’t depend on any third party libraries. The navigation will allow users to switch between pages for houses, apartments, townhomes, and the user’s favorites list. We’ll use what we’ve learned about the Flutter Drawer widget to enhance the app by including a navigation. ElevatedButton, a filled button whose material elevates when pressed. Demo Appįor our demo app, we’ll improve the real estate app that we created in the previous post, The Flutter Visibility Widget: Show and Hide Content. ButtonBar class Null safety TextButton, a simple flat button without a shadow. And for each ListTile, we can set the onTap property to respond to the user’s selection of a navigation link. We use the ListTile widget, which provides a layout that includes an icon and some text, for the navigation links. For the header, we use the UserAccountsDrawerHeader widget that provides a simple layout for user profile information. The header comes first in the ListView, followed by all the navigation links. Furthermore, the ListView will scroll if the list is too long to fit on the screen. The ListView enables us to easily add widgets in a column layout. In this example, we used a ListView widget as the child widget. The Drawer widget has a child property where you can place all the content for the drawer. import 'package:flutter/material.Builder: (BuildContext context) => const MyHomePage( To see how IconButton is used with an Ink widget in a very simple app have a look at the code snippet below.
