Top 5 Best Flutter AppBar Widget List

Flutter AppBar Widget

Flutter AppBar Widget

The term “Flutter AppBar Widgets” describes a button that stays in the screen’s top bar. If you already have a Flutter toolbar, you may use it with the Flutter Appbar. 

Having the app bar serve as a header to specify the page headers is a common practice for making apps more user-friendly and noticeable by the Flutter app development company. On the homepage, you may notice a notification button in the appbar with other action buttons.

Lets Understand About Flutter AppBar Widget

Now that we’ve gone over the fundamentals let’s dive into the ways an Flutter AppBar Widget may be altered to provide user-friendly apps. Here is a rundown of some of the top Flutter AppBar Widget packages:

  1. Basic AppBar

The Flutter Basic AppBar is a versatile widget that may provide a standard top bar to your app. Using a title and two advancing widgets, you may make changes. 

AppBar(

  title: Text(‘Your App’),

  leading: Icon(Icons.menu),

  actions: [IconButton(icon: Icon(Icons.search), onPressed: () {})],

)

title: The main title of the app that shows on the bar. The default option will be “Your App” and this will use it without your intervention.

leading: the displayed widget. For the sake of this example, it represents a menu.

actions: a collection of widgets that will be shown in the sidebar of the app on the right. A search icon button is shown on this page.

  1. AppBar with Tab

This basic Flutter AppBar Widget may be taken to the next level by adding more actions, changing the primary symbol, or customizing the title. This might serve as the foundation for a variety of app concepts.

DefaultTabController(

  length: 3,

  child: Scaffold(

    appBar: AppBar(

      title: Text(‘Tabs Example’),

      bottom: TabBar(tabs: [

        Tab(text: ‘Tab 1’),

        Tab(text: ‘Tab 2’),

        Tab(text: ‘Tab 3’),

      ]),

    ),

    body: TabBarView(children: [

      // Content for Tab 1

      // Content for Tab 2

      // Content for Tab 3

    ]),

  ),

)

If you’re planning to include tabs in your product, the Flutter AppBar Widget with Tabs is an excellent tool to have available. Combining TabBar and TabBarView with the DefaultTabController should do the trick. 

DefaultTabController: This class manages the TabBarView and DefaultTabController tab controllers. You may choose the number of tabs to use using the length option.

Scaffold: The app bar and the page’s basic structure are both enabled by the scaffold.

TabBar: You can view the names of all the tabs in the tab bar. In this example, Tab1, Tab2, and Tab 3 make up the whole.

TabBarView: The TabBarView keeps track of all the tab data. The contents of each tab may be customized to suit the requirements of your application.

Users have the option to drag and drop the tabs on the app bar to switch between different viewpoints. It is possible to maintain synchronization between the TabBar and TabBarView by using the DefaultTabController.

  1. SliverAppBar

For cases calling for complex scrolling effects, such as collapsible headers, the flexible app bar SliverAppBar, which is compatible with CustomScrollView, is a great pick.

You can make a lot of slivers using scrollable views like CustomScrollView. This flexible container allows you to create your one-of-a-kind scrolling effects.

CustomScrollView(

  slivers: [

    SliverAppBar(

      expandedHeight: 200.0,

      floating: false,

      pinned: true,

      flexibleSpace: FlexibleSpaceBar(

        title: Text(‘Sliver App Bar’),

        background: Image.network(

          ‘https://example.com/image.jpg’,

          fit: BoxFit.cover,

        ),

      ),

    ),

    // Other sliver components

  ],

)

Applying the expanded height property, you can determine the highest point that the app bar can grow to. To enable scrolling, set this parameter to true. The app bar will float over the content. 

When the “pinned” option is chosen, the app bar will stay at the top of the screen regardless of how far the user scrolls. You may customize the content of your app bar with the help of the Flutter AppBar widget. Here we have an example that uses a background image and title text.

  1. Collapsing AppBar:

The collapsing app bar is a display style that mimics the SliverAppBar by progressively reducing its size as the user scrolls down the page. App bars often include a folding part that may reveal extra material.  Now let’s look at this example:

CustomScrollView(

  slivers: [

    SliverAppBar(

      expandedHeight: 200.0,

      floating: false,

      pinned: true,

      flexibleSpace: FlexibleSpaceBar(

        title: Text(‘Collapsing App Bar’),

        background: Image.network(

          ‘https://example.com/image.jpg’,

          fit: BoxFit.cover,

        ),

      ),

    ),

    SliverList(

      delegate: SliverChildBuilderDelegate(

        (BuildContext context, int index) {

          return ListTile(title: Text(‘Item $index’));

        },

        childCount: 100,

      ),

    ),

  ],

)

No matter how many pixels higher anything else is, the SliverAppBar will remain at the top.

As a header, the FlexibleSpaceBar skillfully blends the title and background image.

You may see a SliverList with 100 items, all of which are ListTile widgets, below the app bar.

To access the list of items, just scroll down the app bar. A more dynamic and engaging collapse effect enhances the user experience.

The SliverAppBar and the folding app bar are two essential parts of Flutter AppBar Widget applications that make scrolling engaging and beautiful. They are perfect for situations when there is little room but a visually beautiful interface is still needed.

  1. AppBar with Drawer

One common Flutter UI paradigm that helps give side-by-side navigation possibilities is the AppBar with Drawer. 

Scaffold(

  appBar: AppBar(

    title: Text(‘App with Drawer’),

  ),

  drawer: Drawer(

    child: // Drawer content

  ),

  body: // Main content

)

The app’s title bar is often located at the screen’s top. This is how the drawer is now configured. A “drawer” style hidden menu that pulls out from the side is what this word is describing. To make the drawer your own, you may use a variety of widgets.

The app bar is left unchanged in this setup, but a drawer is provided for users to access additional functionality or navigation options. The display of the app’s functionality is both methodical and user-friendly, which is rather impressive.

Conclusion 

Last but not least, the Flutter AppBar Widget is a must-have for every app’s UI. No matter what kind of interface you’re aiming for—a basic navigation bar, tabbed, collapsible, or side drawer—the AppBar may be customized to suit your requirements. 

The flexibility and composability of Flutter widgets allow developers to build aesthetically pleasing and functional user interfaces. You should hire flutter app developers for the best help.
