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.

Inheritance

• Object
• DiagnosticableTree
• Widget
• StatelessWidget
• Nested
• MultiProvider

Implemented types

• SingleChildWidget

Constructors

MultiProvider({Key? key, required List<SingleChildWidget> providers, Widget? child, TransitionBuilder? builder})

Build a tree of providers from a list of SingleChildWidget.

Properties

hashCode → int

The hash code for this object.

no setter, inherited

key → Key?

final, inherited

runtimeType → Type

A representation of the runtime type of the object.

no setter, inherited

Methods
