MultiRepositoryProvider constructor

MultiRepositoryProvider({
  1. required List<SingleChildWidget> providers,
  2. required Widget child,
  3. Key? key,
})

Merges multiple RepositoryProvider widgets into one widget tree.

MultiRepositoryProvider improves the readability and eliminates the need to nest multiple RepositoryProviders.

By using MultiRepositoryProvider we can go from:

RepositoryProvider<RepositoryA>(
  create: (context) => RepositoryA(),
  child: RepositoryProvider<RepositoryB>(
    create: (context) => RepositoryB(),
    child: RepositoryProvider<RepositoryC>(
      create: (context) => RepositoryC(),
      child: ChildA(),
    )
  )
)

to:

MultiRepositoryProvider(
  providers: [
    RepositoryProvider<RepositoryA>(create: (context) => RepositoryA()),
    RepositoryProvider<RepositoryB>(create: (context) => RepositoryB()),
    RepositoryProvider<RepositoryC>(create: (context) => RepositoryC()),
  ],
  child: ChildA(),
)

MultiRepositoryProvider converts the RepositoryProvider list into a tree of nested RepositoryProvider widgets. As a result, the only advantage of using MultiRepositoryProvider is improved readability due to the reduction in nesting and boilerplate.

Implementation

MultiRepositoryProvider({
  required List<SingleChildWidget> providers,
  required Widget child,
  Key? key,
}) : super(key: key, providers: providers, child: child);
