isPaused property
Whether the run is parked rather than running. Three things park it:
the network (under NetworkMode.online a mutation submitted offline
sits here until the device is back, when a mounted client resumes it
through resumePausedMutations), focus (a retry waits for the app to
return to the foreground), and its MutationScope — a mutation queued
behind another in its scope is pending with isPaused until its
turn. Show "waiting" rather than "saving" while it is set.
Implementation
final bool isPaused;
