07/27/2022, 9:08 PMHi, what is the suggested way to set a flow configuration value, like a sandbox API URL, across a flow-of-flows? We are currently using Parameters, but it appears I can only set paramters for the parent flow in the UI. I can’t directly set the child flow parameters, too.

client.create_flow_runparametersI saw you already mentioned that you're currently sticking with prefect 1.0, but just for context its worth mentioning that in prefect 2.0 its much simpler, you can just call any
@flow Copy code
from prefect import flow, task
@task(name="Print Hello")
def print_hello(name):
msg = f"Hello {name}!"
print(msg)
return msg
@flow(name="My Subflow")
def my_subflow(msg):
print(f"Subflow says: {msg}")
@flow(name="Hello Flow")
def hello_world(name="world"):
message = print_hello(name)
my_subflow(message)
hello_world("Marvin")gratitude thank you 1
