share variables between flows?

[F]

Good evening. how to exchange variables between flows? I read that there are no global variables and that the only solution is to use files (text for example).
Do you think the use of global variables will appear in automate one day perhaps?
this would be significantly simpler than using files.

1. Use separate Flow beginning, possibly hidden, that accepts a "payload" from another flow using the Flow start block. Then use the Variables give and take, or Atomic block, to access the values by the different fibers within the flow.
2. Use Broadcast send and receive blocks form different flows.
3. Use a database.
4. Use a JSON file.

Seems there is a bug in version 1.47.2 because it is not possible to enter numbers or a slash in a Variables take block in the field Output variables (Giver fiber URI).

That's never been possible, the output fields only accept variable names, not expressions.
