MultiProvider class
A provider that merges multiple providers into a single linear widget tree. It is used to improve readability and reduce boilerplate code of having to nest multiple layers of providers.
As such, we're going from:
Provider<Something>(
create: (_) => Something(),
child: Provider<SomethingElse>(
create: (_) => SomethingElse(),
child: Provider<AnotherThing>(
create: (_) => AnotherThing(),
child: someWidget,
),
),
),
To:
MultiProvider(
providers: [
Provider<Something>(create: (_) => Something()),
Provider<SomethingElse>(create: (_) => SomethingElse()),
Provider<AnotherThing>(create: (_) => AnotherThing()),
],
child: someWidget,
)
The widget tree representation of the two approaches are identical.
