RepositoryProvider<T> class

Takes a Create function that is responsible for creating the repository and a child which will have access to the repository via RepositoryProvider.of(context). It is used as a dependency injection (DI) widget so that a single instance of a repository can be provided to multiple widgets within a subtree.

RepositoryProvider(
  create: (context) => RepositoryA(),
  child: ChildA(),
);

Lazily creates the repository unless lazy is set to false.

RepositoryProvider(
  lazy: false,`
  create: (context) => RepositoryA(),
  child: ChildA(),
);

Constructors

RepositoryProvider({required Create<T> create, Key? key, Widget? child, bool? lazy})
Takes a Create function that is responsible for creating the repository and a child which will have access to the repository via RepositoryProvider.of(context). It is used as a dependency injection (DI) widget so that a single instance of a repository can be provided to multiple widgets within a subtree.
RepositoryProvider.value({required T value, Key? key, Widget? child})
Takes a repository and a child which will have access to the repository. A new repository should not be created in RepositoryProvider.value. Repositories should always be created using the default constructor within the Create function.
