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(),
);

which will have access to the repository viaRepositoryProvider.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 inRepositoryProvider.value
. Repositories should always be created using the default constructor within theCreate
function.
