Bloc observer flutter code#
The code works fine when the app is started with the internet connection turned on. I have followed this post and this post to set up an Internet Cubit for the project. It also has a lot of management options for views or widgets. What’s next We’re experimenting with Flutter APIs to expose the BlocOverrides API within the context of the widget tree. I am trying to use the BLoC library with the connectivityplus plugin in Flutter. However, rather than calling a function on a Bloc and directly emitting a new state, Blocs receive events and convert the incoming events into outgoing states. Bloc also extends BlocBase which means it has a similar public API as Cubit. But you need to initialize cubit observer first, we initialize it in the. Bloc A Bloc is a more advanced class which relies on events to trigger state changes rather than functions. To summarize, Flutter is great because it's understandable and not complicated to use. Actually Cubit is a cocktail of Flutter Bloc and Provider where we use some. Using good state management is essential when building flutter applications.
