Subscribe to realtime changes in your database.

  • Realtime is disabled by default for new Projects for better database performance and security. You can turn it on by managing replication.
  • If you want to receive the "previous" data for updates and deletes, you will need to set REPLICA IDENTITY to FULL, like this: ALTER TABLE your_table REPLICA IDENTITY FULL;

  ChannelFilter(event: '*', schema: '*'),
  (payload, [ref]) {
    print('Change received: ${payload.toString()}');
