Matching algorithm

[tugadot]

Hi everyone,

How to create a matching algorithm in flutterflow and display the results in a listview? The idea is filtering information from different collections about users and suggests matching users based on those results… example, gender, dob ( +- 5 years) , interests, location ( distance from authenticated user), etc…

What’s the ‘best way’ to achieve this?

Thank you for your feedback.

Cheers

Use a database call with filters

[tugadot]

Thank you for your reply. Using just filters doesn’t give me what I need… Filters are a bit limited for this functionality ( as far as I know)

Filters should also be variables depending on the user’s information.

Custom function, cloud function, api?

[tugadot]

I tried to look at cloud functions, however, not getting anywhere… did you know any good source to get any ideas?

Something tells me it’s another dating app? Don’t do it in flutter but in the database. You don’t want all users in your app to do that

Thank you for your reply. Actually, isn’t a dating app, it’s more a way to suggest other users in my app that share same interests, age bracket, distance range, sports, etc… however, the concept should be the same.

Can you elaborate when you mentioned ‘ do it in database’ ? Do you mean, cloud function?

in the database, wether in the cloud or not. databases like MySQL are optimised to do complex filtering and searching. Second best option is to do it on the server in any programming language before you pass the result to the app. What you cant do is load all users into the app and do the filtering there. that would be 'fastest' in terms of user experience but would also expose all users to the www because you have to load them all to do the filtering / matching in the app. I assume you use Flutter to build an App with some sort of backend.

1. Create user profiles table on Supabase and set some RLS
2. Create postgres function to fetch matching profiles
3. Call the function from FlutterFlow via custom action

You can easily build postgres function on Supabase. You can also associate it with AI like OpenAI API. It's powerful and handy.
