Fire Events

By default the framework supports firing three base class events:

• UiEvent
• Command
  • NavigationCommand
• AppEvent

Find pre-defined out-of-the-box supported events here.

UiEvents

The library comes with a few pre-defined UiEvents you can find here.

For example, when a button/label is tapped:

ElevatedButton(
  onPressed: () {
    Buzz.fire(OnTapped());
  },
  child: Text('Tap me!'),
)

Commands

Listen Events

Use the on method from the Buzz instance to get a Stream to listen events of a specific class type.

Here is how you can add a listener for NavigationCommand's:

Buzz.on<NavigationCommand>().listen((navigationCommand) {
  //TODO: Implement navigation command handler
  print(navigationCommand);
});

Customization

Include the Buzz events dashboard

First enable the withDebugDashboard flag from the init method:

Buzz.init(
  withDebugDashboard: true,
  navigator: MyAppNavigator(),
  rootAppRoute: '/',
);

Now you can use the EventsDashboardPage widget. Here is an example on how to declare a route when using Get:

GetPage(
  name: EventsDashboardPage.routeName,
  page: () => const EventsDashboardPage(),
  transition: Transition.fadeIn,
),

Finally, navigate to the events dashboard by running:

Buzz.fire(GoToBuzzEventsDashboard());

or add a custom button that fires the UiEvent already setup during library initialization:

Buzz.fire(GoToBuzzDashboardButtonTapped());

Upcoming Features

• Default navigator using Flutter Navigator 2.0 instead of Get.
