RTCStream Class Events - Flutter

• A RTCStream delivers one event, streamStateChanged. Listen for it with stream.on(). The room does not deliver it.
• To know when a stream is added, removed, paused or resumed, listen on the Room for streamEnabled, streamDisabled, streamPaused and streamResumed.

streamStateChanged

• This event will be emitted when the health of a remote participant's video or screen-share stream changes.
• The handler receives:
  • state (StreamState): the new state:
    • StreamState.ACTIVE: the stream started or resumed receiving. A new stream's first ACTIVE arrives about one second after it is enabled.
    • StreamState.ENDED: the stream stopped and will not produce more media.
    • StreamState.STUCK: no media has arrived for about five seconds.
    • StreamState.FREEZE_DETECTED: the picture froze.
    • StreamState.FREEZE_RESOLVED: the picture recovered, with no new freeze for about five seconds.
  • timestamp (int): when the change arrived, in milliseconds since epoch.
• Remove the handler with off().

Example

room.on(Events.streamEnabled, (RTCStream stream) {
  stream.on(Events.streamStateChanged, (StreamState state, int timestamp) {
    print("${stream.kind.name} stream of ${stream.participantId} is ${state.name}");
  });
});
