Cubit: Advanced Topics

Flutter Warsaw #14

We guess that everyone who has some connection with Flutter knows Felix Angelov, who is our second presenter in 14 edition of Flutter Warsaw Meetup.

Felix is the creator one of the most popular approach of state management in Flutter, called BloC Pattern. But despite its popularity, this solution will not be perfect, at least not for everyone. So to change a little bit this approach Felix created Cubit. Cubit is a replacement or subset as we should say, of a very known Bloc Pattern, with a simplified, lighter combination of the Bloc and Provider. It brings a fresh friendly look to the Bloc state management, especially for those programmers, who do not necessarily know reactive programming.

In this part you will learn:

  • What is Cubit and how to use it
  • What is HydratedBloc
  • How to test your code with BlocTest, and common mistakes in testing
  • From simple to advance examples of using Cubit
  • Whit is ReplayBloc, and undo/redo functionality
