Design a counter app in Flutter with a stateful home screen, text display, and plus minus buttons that update the count, and discuss bloc and other state management options.
Learn to implement a Flutter bloc cubit by creating a counter cubit that extends bloc base, managing an integer state with initial value zero.
Explore how to handle states with Flutter bloc by wiring a counter cubit via bloc provider, rebuilding with bloc builder, and using increment and decrement to output new states.
Wrap the home screen with bloc provider and use bloc consumer to rebuild the text on counter state changes while emitting increment and decrement events.
Explore Flutter bloc architecture by mapping user events to UI states, coordinating with the data layer, and handling errors or data updates to rebuild widgets.
Learn how the bloc provider defines a bloc in the widget tree to expose data and functions and automatically turns off to prevent data leaks.
Learn how Flutter bloc builder, bloc listener, and bloc consumer respond to state changes to efficiently rebuild only necessary widgets and enable actions like navigation or snackbars.
Learn to observe bloc changes with a bloc observer, centralizing state, event, and transition monitoring across multiple cubits, and test behavior via the console and error handling.
Build a Flutter news app using Bloc to manage API requests, errors, caching, and local storage with Dio interceptors, featuring home and category pages with pagination and themes.
Flutter Native splash screen using flutter_native_splash package that help you to customize your native screen with any image you want

Change theme mode from while to dark mode using flutter bloc - specially using cubit and also using shared preferences to cache our data
Learn to design a Flutter category screen with a tab bar and dynamic categories, using a category list, a tab controller, and color styling to build a responsive UI.
Implement a Flutter bloc project by consuming a rest news api with an api key, including top headlines, categories, country, language, and search parameters.
Learn to fetch news data in a Flutter app using Dio, building a data layer, creating a News model, and wiring a Bloc with events, states, and a loading-to-success flow.
Learn how to handle Flutter bloc states, including loading, success, and error, by building user interface with state-aware builder, showing a circular progress indicator during loading, and styled error messages.
Learn to handle API errors in Flutter Bloc by implementing exception and server failure classes, using either with left/right, and emitting robust error states.
Learn how to implement pagination in flutter bloc by using a load more button to fetch additional home news and category news pages, updating state to success.
Learn to use the equatable package in Flutter Bloc to compare states and models by extending Equatable, overriding props, and aligning hashCode for accurate, observable state behavior.
Implement and validate data caching in a Flutter Bloc app by building local and remote data sources, saving home and category news to cache, and managing paginated fetch logic.
Flutter bloc is one of the state management for Flutter applications. You can use it to handle all the possible states of your application in an easy way.
Flutter bloc is simple to use because you and your team are going to understand the concept quickly, no matter what is your level, this library has very good documentation with tons of examples and also, is one of the most used in the flutter community, so if you have any question or problem you probably are going to find the solution with a simple search on the internet.
Is powerful because is going to help you to create all kinds of applications, you can create applications for learning purposes for example, and also you can create complex applications in a production environment and flutter bloc is valid in both cases.
Another important aspect of this library is that you could test your bloc logic in an easy way.
To understand how bloc works, we need to know what are events and states.
Events: events are an application’s inputs (like button_press to load images, text inputs, or any other user input that our app may hope to receive).
States: States are simply the application’s state, which can be changed in response to the event received.
Bloc manages these events and states, i.e., it takes a stream of Events and transforms them into a stream of States as output.
