Subscribe to channel

Subscribe to realtime changes in your database.

Realtime is disabled by default for new tables. 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;


supabase.channel('*').on(
  RealtimeListenTypes.postgresChanges,
  ChannelFilter(event: '*', schema: '*'),
  (payload, [ref]) {
    print('Change received: ${payload.toString()}');
  },
).subscribe();
