Pagination in Flutterflow web project using Supabase

Efficient Pagination with Supabase and FlutterFlow

Overview
Pagination splits large datasets into smaller chunks or "pages" for better performance and user experience in web applications.

Why Pagination?
Using a DataTable with an API in FlutterFlow loads all data at once, which can be slow. Pagination helps reduce loading time and ensures a smoother experience by fetching data dynamically.

Prerequisites

• Supabase: An open-source backend platform providing scalable solutions for databases and APIs.

• FlutterFlow: A low-code platform for building applications visually.

Steps to Implement Pagination

1. Set Up Supabase

   • Create a Supabase project.

   • Enable Row-Level Security (RLS) for your database table.

   • Write SQL functions for paginated data retrieval, like:

     Copy

     CREATE OR REPLACE FUNCTION public.function_name(page_number INT) RETURNS TABLE (id BIGINT, name TEXT, ...) AS $$ BEGIN RETURN QUERY SELECT  FROM table_name ORDER BY id LIMIT limit_var OFFSET (page_number - 1)  limit_var; END; $$ LANGUAGE plpgsql;

2. Set Up FlutterFlow

   • Create a project and enable Supabase authentication.

   • Add the API URL and Anon Key from Supabase in FlutterFlow settings.

3. Integrate API

   • Test your Supabase API in Postman with the endpoint:

     https://<project-ref>.supabase.co/rest/v1/rpc/function_name

   • Add headers (apikey, Authorization, Content-Type) and a JSON body ({"page_number": 1}).

4. Design Pagination in FlutterFlow

   • Create a table UI with widgets.

   • Define page state variables (e.g., page_number, json_list).

   • Fetch data dynamically based on the current page and update the table.

   • Add forward/backward icons to navigate pages.

Conclusion
Supabase and FlutterFlow together make it easy to manage large datasets with pagination. Supabase provides robust backend capabilities, while FlutterFlow simplifies the frontend design.
