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;


final mySubscription = supabase
  .from('countries')
  .on(SupabaseEventTypes.all, (payload) {
    // Handle realtime payload
  })
  .subscribe();
