  <blockquote>
  <p>How does ObjectBox handle concurrent(by different threads/isolates) write requests? example of my use case: FCM &quot;onBackgroundmessage&quot; call runs in a different isolate, the same time multiple write requests might happen. &quot;Hive&quot; is failing in this case completely. Is there any inbuild solution in ObjectBox?</p>
