FactoryProvider

An injection token. (Typically an instance of Type or InjectionToken, but can be any).

When true, injector returns an array of instances. This is useful to allow multiple providers spread across many files to provide configuration information to a common token.

A function to invoke to create a value for this token. The function is invoked with resolved values of tokens in the deps field.

A list of tokens to be resolved by the injector. The list of values is then used as arguments to the useFactory function.
