2 things to look at

  • no licenseNo license file was found in the repository. Code published without one is not open source by default, so using it at work is a question for whoever answers licensing questions where you are.
  • 6 stars6 stars. Stars are a popularity signal and not a quality one, but at this level it is likely that nobody has read this closely except its author, and you would be relying on your own review.

What its author says it does

Supabase Flutter integration for PostgreSQL, Auth, Realtime subscriptions, Storage, Edge Functions, and Row Level Security. Use when building backend features with supabase_flutter or configuring database policies.

Supabase Flutter Ecosystem (supabase_flutter)

Goal

Supabase is an open-source Firebase alternative built on PostgreSQL, supporting rich SQL queries, table joins, and a first-class Flutter SDK (supabase_flutter).

To ensure modularity and LLM readability, this skill is split into logical chapters. Before answering questions or writing code related to Supabase, you MUST read the relevant reference chapters.

Process/Workflow

  1. Identify the core Supabase service the user needs (Database, Auth, Storage, etc.).
  2. Read the corresponding chapter(s) from the references/ directory.
    • Example: If the user asks about deep linking Magic Links for login, read 01-setup.md and 02-auth.md.
  3. Synthesize the guidelines exactly as documented within the chapters. DO NOT hallucinate third-party packages or outdated practices.
  4. Maintain the Serverpod Mini BFF (Backend-For-Frontend) architecture whenever the user requires executing high-privilege operations that should bypass Row Level Security (RLS) entirely.

Reference Files

  • Setup & Deep Links: Read 01-setup.md for core initialization and the app_links requirement.
  • Authentication: Read 02-auth.md for Email/OTP, Apple/Google native sign-in, and listening to stream changes.
  • Database (Postgres): Read 03-database.md for strongly-typed Freezed mapping, .select(), and join strategies natively.
  • Realtime & Presence: Read 04-realtime.md for Postgres CDC subscriptions and User Presence management.
  • Storage: Read 05-storage.md for cross-platform (Mobile vs Web) bucket manipulation.
  • Edge Functions: Read 06-edge-functions.md for executing remote serverless workflows.
  • Serverpod Mini (BFF): Read 07-serverpod-mini.md for leveraging the pure supabase Dart library combined with the SERVICE_ROLE_KEY inside a secure backend.
