Is it a good idea to use the same repository for several BLoCs?
It is a broad question to be asked well according to me, using the same repository for many BLoCs in Flutter is typically not advised.
A repository should be created to fulfil the data requirements of a particular feature or module inside your project as it is often responsible for maintaining a specific data source or API. The architecture of your project will be more flexible and modular if each BLoC has its own repository instance.
You may make sure that the data requirements for each feature are distinct and well-defined by utilising different repositories for each BLoC. This makes it simpler to test and maintain your code. Also, it enables you to alter one aspect without altering others.
A common repository, however, could be appropriate in some circumstances, such as when several features rely on the same data source or when the data is straightforward and doesn't need its own repository. In these situations, it's crucial to carefully weigh the trade-offs and make sure the shared repository is created in a way that satisfies the requirements of all the features that depend on it.
