isFcmActive property
Whether the FCM token is CURRENTLY SYNCED (mirrors NotificationService.isFcmTokenInitialized).
As of 0.12.0 this reflects a confirmed capture/persist that has not since
been invalidated — it is NOT set on a null getToken() and is RESET on a
transient refresh-persist failure. It can therefore read false while the
token refresh listener is still registered and live; the prior "token
acquired and listeners running" wording overstated "listeners running".
Implementation
final bool isFcmActive;
