Injecting providers

You can inject any provider/service you want in the XML file:

<MyPage controller="MyController">
  <provider type="DataService" name="dataService" />
  ...
</MyPage>

Then can be accessed directly in the same XML file, or in the controller class after didLoad(), not in the constructor.

  @override
  void didLoad() {
    dataService.doSomething();
  }

And don't forget to add the provider/service to your providers:

  runApp(
    MultiProvider(
      providers: [
        Provider<DataService>(builder: (_) => DataService())
      ],
      ...
    )
  )

Note If the type of the provider is ChangeNotifierProvider the whole widget will rebuild when the provider changes, and that is by design, so if you don't want to rebuild the whole widget try using :consumer for this case.
