BLoC
BLoC
stands for Business Logic Component. It is a state management pattern and library in Flutter for managing the flow of data between the UI layer and the business logic layer of an application. It
helps to separate the presentation layer from the business logic layer, making the code more modular and easier to maintain.
In BLoC, the business logic layer is represented by a set of components called "BLoCs". Each BLoC is responsible for handling a specific part of the application's logic and data. The BLoCs expose a set of streams and sinks, which are used to send and receive data between the UI layer and the business logic layer.
The UI layer interacts with the BLoC using "StreamBuilder" widgets, which listen to the BLoC's streams and update the UI whenever new data is received. When the user interacts with the UI, the UI layer sends events to the BLoC using "Sink" widgets, which triggers the corresponding business logic.
Overall, BLoC is a powerful state management pattern and library in Flutter, and it is widely used by developers to build scalable and maintainable applications.
Inherited Widget
Inherited Widget is a Flutter library that provides a way to efficiently share data across a widget tree. An Inherited Widget is a widget that can be passed down from a parent widget to its descendants, carrying with it some data that can be accessed by its descendants. When the data changes, the Inherited Widget rebuilds the descendants that depend on the data, but avoids rebuilding the entire widget tree, which can be expensive and time-consuming
Inherited Widget is particularly useful for managing application state across a widget tree. Instead of passing state down manually through callbacks, an Inherited Widget can be used to pass the state down automatically, making it easier to manage and update the state as needed. In addition, Inherited Widget can help to reduce the amount of boilerplate code needed to manage state, making the code more concise and readable.
Overall, Inherited Widget is a powerful Flutter library that can help to simplify state management and improve the performance of widget trees by efficiently sharing data across them.
Provider
