Create<T, R extends Ref> typedef Null safety

Create<T, R extends Ref> = T Function(R ref)

A callback used by providers to create the value exposed.

If an exception is thrown within that callback, all attempts at reading the provider associated with the given callback will throw.

The parameter ref can be used to interact with other providers and the life-cycles of this provider.

See also:

• Ref, which exposes the methods to read other providers.
• Provider, a provider that uses Create to expose an immutable value.

Implementation

typedef Create<T, R extends Ref> = T Function(R ref);
