fetchResource<T> method Null safety

Future<T> fetchResource<T>(
  1. Resource<T> resource
)

Gets an instance provided by resource which is guaranteed to be unique within a single build, and may be reused across build steps within a build if the implementation allows.

It is also guaranteed that resource will be disposed before the next build starts (and the dispose callback will be invoked if provided).

Implementation

Future<T> fetchResource<T>(Resource<T> resource);
