Flutter app Bar and search Widget Integrated

Loader SearchBar Flutter widget integrating search field feature into app bar, allowing to receive query change callbacks and automatically load new data set into ListView. It replaces standard AppBar widget and needs to be placed underneath Scaffold element in the widget tree to work properly.

Loader SearchBar demo

Getting started

To start using SearchBar insert it in place of an AppBar element in the Scaffold widget. Regardless of the use case, defaultBar named argument has to be specified, which basically is a widget that will be displayed whenever SearchBar is not in activated state:

@override
Widget build(BuildContext context) {
   return Scaffold(
     appBar: SearchBar(
       defaultBar: AppBar(
         leading: IconButton(
           icon: Icon(Icons.menu),
           onPressed: _openDrawer,
         ),
         title: Text('Default app bar title'),
       ),
       ...
     ),
     body: _body,
     drawer: _drawer,
   );
}

Optional attributes

  • searchHint - hint string being displayed until user inputs any text,
  • initialQuery - query value displayed for the first time in search field,
  • iconified - boolean value indicating way of representing non-activated SearchBar:
    • true if widget should be showed as an action item in defaultBar,
    • false if widget should be merged with defaultBar (only leading icon of the default widget and search input field are displayed in such case),
  • autofocus - boolean value determining if search text field should get focus whenever it becomes visible,
  • autoActive - ,
  • attrs - SearchBarAttrs class instance allowing to specify part of exact values used during widget building (e.g. search bar colors, text size, border radius),
  • controller - SearchBarController object that provides a way of interacing with current state of the widget,
  • searchItem - defining how to build and position search item widget in app bar,
  • overlayStyle - status bar overlay brightness applied when widget is activated.

Query callbacks

To get notified about user input specify onQueryChanged and/or onQuerySubmitted callback functions that receive current query string as an argument:

appBar: SearchBar(
   ...
   onQueryChanged: (query) => _handleQueryChanged(context, query),
   onQuerySubmitted: (query) => _handleQuerySubmitted(context, query),
),

QuerySetLoader

By passing QuerySetLoader object as an argument one can additionally benefit from search results being automatically built as ListView widget whenever search query changes:

appBar: SearchBar(
  ...
  loader: QuerySetLoader<Item>(
     querySetCall: _getItemListForQuery,
     itemBuilder: _buildItemWidget,
     loadOnEachChange: true,
     animateChanges: true,
  ),
),

List<Item> _getItemListForQuery(String query) { ... }

Widget _buildItemWidget(Item item) { ... }
  • querySetCall - function transforming search query into list of items being then rendered in ListView (required),
  • itemBuilder - function creating Widget object for received item, called during ListView building for each element of the results set (required),
  • loadOnEachChange - boolean value indicating whether querySetCall should be triggered on each query change; if false query set is loaded once user submits query,
  • animateChanges - determines whether ListView’s insert and remove operations should be animated.

SearchItem

Specifying this parameter allows to customize how search item should be built and positioned in app bar. It can be either action or menu widget. No matter which of these two is picked, two constructor arguments can be passed:

  • builder - function receiving current BuildContext and returning Widget for action or PopupMenuItem for menu item,
  • gravity - can be one of SearchItemGravity values: start, end or exactly. If no arguments are passed, SearchBar will create default item which is search action icon with start gravity.

SearchItem.action

Search action item

appBar: SearchBar(
  // ...
  searchItem: SearchItem.action(
    builder: (_) => Padding(
      padding: EdgeInsets.all(12.0),
      child: Icon(
        Icons.find_in_page,
        color: Colors.indigoAccent,
      ),
    ),
    gravity: SearchItemGravity.exactly(1),
  ),
)

SearchItem.menu

Search menu item

appBar: SearchBar(
  // ...
  searchItem: SearchItem.menu(
    builder: (_) => PopupMenuItem(
      child: Text("Search  🔍"),
      value: "search",
    ),
    gravity: SearchItemGravity.end,
  ),
)

Also, bear in mind that SearchBar will prevent built item widget from receiving tap events and will begin search action rather than that.

Google's Flutter 1.20 stable announced with new features - Navoki

Flutter Google cross-platform UI framework has released a new version 1.20 stable.

Flutter is Google’s UI framework to make apps for Android, iOS, Web, Windows, Mac, Linux, and Fuchsia OS. Since the last 2 years, the flutter Framework has already achieved popularity among mobile developers to develop Android and iOS apps. In the last few releases, Flutter also added the support of making web applications and desktop applications.

Last month they introduced the support of the Linux desktop app that can be distributed through Canonical Snap Store(Snapcraft), this enables the developers to publish there Linux desktop app for their users and publish on Snap Store.  If you want to learn how to Publish Flutter Desktop app in Snap Store that here is the tutorial.

Flutter 1.20 Framework is built on Google’s made Dart programming language that is a cross-platform language providing native performance, new UI widgets, and other more features for the developer usage.

Here are the few key points of this release:

Performance improvements for Flutter and Dart

In this release, they have got multiple performance improvements in the Dart language itself. A new improvement is to reduce the app size in the release versions of the app. Another performance improvement is to reduce junk in the display of app animation by using the warm-up phase.

sksl_warm-up

If your app is junk information during the first run then the Skia Shading Language shader provides for pre-compilation as part of your app’s build. This can speed it up by more than 2x.

Added a better support of mouse cursors for web and desktop flutter app,. Now many widgets will show cursor on top of them or you can specify the type of supported cursor you want.

Autofill for mobile text fields

Autofill was already supported in native applications now its been added to the Flutter SDK. Now prefilled information stored by your OS can be used for autofill in the application. This feature will be available soon on the flutter web.

flutter_autofill

A new widget for interaction

InteractiveViewer is a new widget design for common interactions in your app like pan, zoom drag and drop for resizing the widget. Informations on this you can check more on this API documentation where you can try this widget on the DartPad. In this release, drag-drop has more features added like you can know precisely where the drop happened and get the position.

Updated Material Slider, RangeSlider, TimePicker, and DatePicker

In this new release, there are many pre-existing widgets that were updated to match the latest material guidelines, these updates include better interaction with Slider and RangeSlider, DatePicker with support for date range and time picker with the new style.

flutter_DatePicker

New pubspec.yaml format

Other than these widget updates there is some update within the project also like in pubspec.yaml file format. If you are a flutter plugin publisher then your old pubspec.yaml  is no longer supported to publish a plugin as the older format does not specify for which platform plugin you are making. All existing plugin will continue to work with flutter apps but you should make a plugin update as soon as possible.

Preview of embedded Dart DevTools in Visual Studio Code

Visual Studio code flutter extension got an update in this release. You get a preview of new features where you can analyze that Dev tools in your coding workspace. Enable this feature in your vs code by _dart.previewEmbeddedDevTools_setting. Dart DevTools menu you can choose your favorite page embed on your code workspace.

Network tracking

The updated the Dev tools comes with the network page that enables network profiling. You can track the timings and other information like status and content type of your** network calls** within your app. You can also monitor gRPC traffic.

Generate type-safe platform channels for platform interop

Pigeon is a command-line tool that will generate types of safe platform channels without adding additional dependencies. With this instead of manually matching method strings on platform channel and serializing arguments, you can invoke native class and pass nonprimitive data objects by directly calling the Dartmethod.

There is still a long list of updates in the new version of Flutter 1.2 that we cannot cover in this blog. You can get more details you can visit the official site to know more. Also, you can subscribe to the Navoki newsletter to get updates on these features and upcoming new updates and lessons. In upcoming new versions, we might see more new features and improvements.
