The implementation currently in use. This should be one of the following depending on the platform in use and the functionality supported by this extension:

• Android
• iOS
• default
• unknown

The singleton instance of the FirebaseDatabase class.

Whether the current device supports the extensions functionality

The native version string of the native extension.

The singleton instance of the FirebaseDatabase class.

The version of this extension. This will be of the format, MAJOR.MINOR.BUILD

Constructor You should not call this directly, but instead use the singleton access

Disposes the extension and releases any allocated resources. Once this function has been called, a call to init is neccesary again before any of the extensions functionality will work.

During the course of using the Firebase Realtime Database extension you will be creating and destroying references and queries that may not get immediately disposed. If you need to manage memory and remove some items you can call this function to dispose any references and queries that have been created and do not have active event listeners. You should make sure that any references you are holding onto either have an event listener or are released after calling this function.

Gets a DatabaseReference for the provided path.

Parameters

Gets a DatabaseReference for the provided URL. The URL must be a URL to a path within this FirebaseDatabase. To create a DatabaseReference to a different database, create a FirebaseApp with a FirebaseOptions object configured with the appropriate database URL.

Parameters

The version for this build of the Firebase Database client

Shuts down the connection to the Firebase Database backend until goOnline() is called.

Resumes the connection to the Firebase Database backend after a previous goOffline() call.

Initialises the extension class for use with the provided key.

Parameters

The Firebase Database client automatically queues writes and sends them to the server at the earliest opportunity, depending on network connectivity. In some cases (e.g. offline usage) there may be a large number of writes waiting to be sent. Calling this method will purge all outstanding writes so they are abandoned. All writes will be purged, including transactions and onDisconnect() writes. The writes will be rolled back locally, perhaps triggering events for affected event listeners, and the client will not (re-)send them to the Firebase backend.

Set the url for the database to access

Parameters

The Firebase Database client will cache synchronized data and keep track of all writes you've initiated while your application is running. It seamlessly handles intermittent network connections and re-sends write operations when the network connection is restored. However by default your write operations and cached data are only stored in-memory and will be lost when your app restarts. By setting this value to `true`, the data will be persisted to on-device (disk) storage and will thus be available again when the app is restarted (even when there is no network connectivity at that time). Note that this method must be called before creating your first Database reference and only needs to be called once per application.
