transferBackToLocal?​

optional transferBackToLocal?: boolean;

Defined in: packages/cast/src/types.ts:109

true (the transfer-back flow): stop receiver playback — read the last mediaStatus position first and resume locally from it. false: just disconnect, without transferring playback back to this device.

CEILING on BOTH platforms: false cannot leave the receiver playing when this phone is the only sender.

Android (cast framework 22.3.1), measured on hardware: every teardown path was tried — endCurrentSession(false) with the stop-receiver option on and off, and a raw MediaRouter.unselect(UNSELECT_REASON_DISCONNECTED) — and the framework stopped receiver playback on session end every time, even though the receiver itself demonstrably supports last-sender-leave continuation (a bare pychromecast sender's disconnect left the same queue playing).

iOS says so in its own header: -[GCKSessionManager endSessionAndStopCasting:] documents that the flag "only applies when multiple sender devices are connected" and that "if only one sender device is connected, the receiver app stops casting the media and ignores the stopCasting value, even if it's set to NO" (GoogleCast 4.8.6, GCKSessionManager.h).

What false still honestly delivers on both: local playback is not resumed, the receiver app is left to idle out rather than being explicitly stopped, and with another sender still attached the receiver does keep playing.
