MultiLiveStreamProvider class
Merges multiple LiveStreamProvider widgets into one widget tree.
MultiLiveStreamProvider improves the readability and eliminates the need to nest multiple LiveStreamProviders.
By using MultiLiveStreamProvider we can go from:
LiveStreamProvider<LiveStreamA>(
create: (BuildContext context) => LiveStreamA(),
child: LiveStreamProvider<LiveStreamB>(
create: (BuildContext context) => LiveStreamB(),
child: LiveStreamProvider<LiveStreamC>(
create: (BuildContext context) => LiveStreamC(),
child: ChildA(),
)
)
)
to:
MultiLiveStreamProvider(
providers: [
LiveStreamProvider<LiveStreamA>(
create: (BuildContext context) => LiveStreamA(),
),
LiveStreamProvider<LiveStreamB>(
create: (BuildContext context) => LiveStreamB(),
),
LiveStreamProvider<LiveStreamC>(
create: (BuildContext context) => LiveStreamC(),
),
],
child: ChildA(),
)
MultiLiveStreamProvider converts the LiveStreamProvider list into a tree of nested LiveStreamProvider widgets. As a result, the only advantage of using MultiLiveStreamProvider is improved readability due to the reduction in nesting and boilerplate.
