ValueProvider<T extends Object> class

Describes at compile-time using a constant value to represent a token.

It is recommended to use useValue with an OpaqueToken as token:

const animationDelay = OpaqueToken<Duration>('animationDelay');

const ValueProvider.forToken(animationDelay, Duration(seconds: 1));

NOTE: The AngularDart compiler has limited heuristics for supporting complex nested objects beyond simple literals, including collection literals like a List or Map where you might expect specific reified types. If you encounter problems it is recommended to use FactoryProvider instead.
