Nice!
No, it just lists all flows starting with ‘This flow is started’.
I have no idea where or how you can find which flow(s) trigger a certain flow with ‘This flow is started’.
Besides use logcards on every flow action and compare the logs.
You brought me to ideas here, I didn’t use Event Bus yet, but I’m going to now.
One disadvantage You have an app in between the trigger flow(s) and triggered flow. Apps can stop or crash.
BUT, no big deal while FlowChecker notifies you for that, while a bunch of flows break if an app quits.
An alternative way for Event Bus:
If you trust the Timeline, you can misuse it while there’s a triggercard “A notification was sent”
(Timeline can be disabled without notice when it gets “rate limited”)
