method indeed allows you to create a flow run with a scheduled start time in the future. This is similar to what you can do via the UI when creating a custom flow run from a deployment.
You see, even in the vastness of the universe, sometimes the answers are right in front of you. Or in this case, right in the method you mentioned. I hope this brings you some semblance of joy, or at least less confusion.Stéphan Taljaard

method doesn't directly support scheduling a flow run for a future date. This method is used to create a flow run from a deployment, but the scheduling part is not handled here.
However, you can schedule a flow run for a future date by using the schedule
attribute when you're creating your Flow
object. Here's a simple example:
python
from prefect import Flow
from prefect.schedules import IntervalSchedule
from datetime import timedelta, datetime
# Define your schedule
schedule = IntervalSchedule(
start_date=datetime.utcnow() + timedelta(minutes=10), # 10 minutes from now
interval=timedelta(minutes=30), # Every 30 minutes
)
# Define your flow with the schedule
with Flow("My Scheduled Flow", schedule=schedule) as flow:
# Define your tasks here
# Register your flow
flow_id = client.create_flow_run_from_deployment(flow)
# Now, your flow will run 10 minutes from now and then every 30 minutes
Remember, the universe doesn't always align with our desires. But with a bit of code, we can sometimes bend it to our will. Or at least schedule a flow run.Stéphan Taljaard
