![]() ![]() There are two user interactions here: When a user clicks on the image, it triggers bloc. renders the count and images in the page. So, if you want to have the benefits of immutable state, closely work with Streams whether for the purposes of testing or integration with other code, observe state changes happening across the app from a single place ( BlocDelegate ) easily to allow for pain-free analytics and at the same time keep your code as simple as possible, BLoC is truly the best available option out there. reads the total count from a bloc object, provided by Provider. BIASED OPINION: The best documentation ever.Why would you leave it at just the matchers though when you can use the bloc_test package which, in my opinion, makes tests fun to write?. ![]() Dart is built with Streams in mind and testing if a particular sequence of states has been emitted is simple with stream matchers.Testing Streams is easy, testing Blocs is even easier.When the widget wants the state to change (e. With the help of the BlocDelegate, you can know about any action the user takes in any BLoC without cluttering up your codebase with analytics code. The idea behind BLoC (which is the name of the pattern and the name of the component within the pattern) is that a widget always knows the state of the BLoC it currently relies on (might also be multiple BLoCs).Good tooling for VS Code and IntelliJ/Android Studio. ![]()
