Counter - an example of how to create a CounterBloc to implement the classic Flutter Counter app.Counter - an example of how to create a CounterBloc (pure dart).ensuring the UI is displaying the correct tasks when a date is selected on the calendarįor now, let's only worry about creating a bloc that can handle the simplest task: fetching tasks from the repository and emitting them via streams.marking tasks as complete or incomplete,.fetching all tasks from the repository, and delivering them to the UI.Looking at the finished app, we know that this bloc needs to handle a few tasks: In short, it's the middleman between the data (source of truth) and the UI displaying that data. It is also responsible for telling the API whenever a task is marked as complete (or incomplete). In other words, the UI will get all of it's state about which tasks exist from this bloc, which will pull it's data from an API. The todo list bloc is responsible for connecting a repository to the the todo list page of the app. In this app, there are two blocs: a TodoListBloc and an AddTodoBloc. If you're not familiar with Flutter as a UI library, I suggest you go back and start at an earlier tutorial. Thus, we'll dive right into blocs in this tutorial, and not focus much on UI. This portion of FlutterByExample is all about state management.
