So in Prefect 2, task objects have a handle

submit()

method that lets you create task objects and them submit them directly, using

wait_for

to specify dependencies. Is there any similar mechanism for sub flows? I am interested in launching a "subflow" but without directly calling the annotated flow method, because I don't know which method I'm calling until runtime. For example, I would like to do this:

result = make_rpc_call()
newflow = Flow(
   name=result.name,
   parameters=result.parameters,
).submit(wait_for=[...])

is this possible?

Hi David, the

.submit

is not available yet for Flows and you can track the status on this issue. Until then you can use the

run_deployment

command to trigger the subflow.

Awesome thanks!
