Pass Started Flow Back via Managed Player by KetanReddy · Pull Request #881 · player-ui/player

KetanReddy · 2026-06-15T16:53:03Z

Enables the instantiator of Managed Player to be notified of the flow Player has started to allow any desired runtime affects for the containing app.

As Android/iOS's Managed Player paradigms don't have this callback (and this is a non-breaking change) we can ship this change just on React for now.

Yeah not too sure why the main 1.0 branch isn't failing? This might have been cut from a older commit?
