<T extends Resource> Stream<T>

provide(ResourceRequest<T> requested)

Provide the requested resources.

Method Details
- provide
  
  <T extends Resource> Stream<T> provide(ResourceRequest<T> requested)
  
  Provide the requested resources. This method is not intended to be invoked directly. Rather, it must be invoked via BuildContext.resources(ResourceProvider, ResourceRequest).
  
  When properly invoked through BuildContext.resources(ResourceProvider, ResourceRequest), this method is never invoked concurrently for the same request. It may, however, be invoked concurrently for different requests. Providers that evaluate all possibly provided resources anyway and return only a subset for some kinds of request should therefore invoke themselves (through BuildContext.resources(ResourceProvider, ResourceRequest)) with a request for all resources and filter the (automatically cached) result.
  
  Type Parameters:
  
  T - the type of the requested (and provided) resource
  
  Parameters:
  
  requested - the requested resources
  
  Returns:
  
  the provided resource(s) as stream
