Running my flutter app in debug mode using firebase_dart 1.1.0-dev.10 sometimes the following error is thrown:

`[ERROR:flutter/runtime/dart_vm_initializer.cc(41)] Unhandled Exception: 'package:firebase_dart/src/database/impl/persistence/tracked_query.dart': Failed assertion: line 343 pos 12: 'existing == null || existing.id == query.id': is not true.

The cause of this exception seems to be located in the storage file firebase-db-persistence-storage-.hive
Removing this file results in the assertion error not be thrown anymore.
