currentSystemFrameTimeStamp property

Duration currentSystemFrameTimeStamp

The raw time stamp as provided by the engine to Window.onBeginFrame for the frame currently being processed.

Unlike currentFrameTimeStamp, this time stamp is neither adjusted to offset when the epoch started nor scaled to reflect the timeDilation in the current epoch.

On most platforms, this is a more or less arbitrary value, and should generally be ignored. On Fuchsia, this corresponds to the system-provided presentation time, and can be used to ensure that animations running in different processes are synchronized.

Implementation

Duration get currentSystemFrameTimeStamp {
  assert(_lastRawTimeStamp != null);
  return _lastRawTimeStamp;
}
