Add support for multiple filters / complex queries for Realtime and stream methods

[davoutuk]

For my Flutter app I was trying to build a dynamic filtering facility for a Supabase stream, and have discovered that an exception is thrown whenever more than one filter is applied.

Why this limit?

Is there any way around this? In my case I have want to apply two field filters and the exact two fields can vary according to user interactions

You can only have one filter on stream() due to the limitation on Supabase's realtime server currently. There is a issue on realtime repo discussing supporting more flexible queries supabase/realtime#303.

I have a workaround, by having a separate column, with the concatenated values, updated by a trigger. Easy if you just want 'eq' but you'll have to get creative if you want gt, lt etc.

Even better, as far as dirty hacks go 😅, is to use a generated column.

+1 this is something that FlutterFlow users have asked for :)
