tracelet_supabase 3.5.5

Supabase adapter for Tracelet. Automatically configures Tracelet's native HTTP sync to push locations to Supabase and manages background auth token refresh.

Tracelet Supabase Adapter

The official Supabase adapter for Tracelet.

This adapter seamlessly connects Tracelet's battery-efficient native HTTP sync engine directly to your Supabase project. It automatically configures Tracelet to push locations to a Postgres RPC function or Edge Function, and manages background auth token (JWT) refresh natively.

🚀 Features

• Direct Postgres Sync — Sync locations straight into your Supabase database via an RPC function, bypassing middleman servers.
• Edge Function Support — Alternatively, route locations through a Supabase Edge Function for custom processing before insertion.
• Auto Token Refresh — Automatically detects 401 Unauthorized errors in the background and refreshes the Supabase Auth session natively, even when the Flutter app is terminated.
• Batch Syncing — Fully compatible with Tracelet's robust HTTP batch engine (exponential backoff, offline queues, Wi-Fi-only sync).
• Enterprise Tested — 100% test coverage using Mocktail and Dependency Injection.

📦 Getting Started

1. Set up Supabase in your Flutter app using supabase_flutter.
2. Initialize Tracelet using TraceletSupabase.

import 'package:supabase_flutter/supabase_flutter.dart';
import 'package:tracelet_supabase/tracelet_supabase.dart';
import 'package:tracelet/tracelet.dart';

void main() async {
  WidgetsFlutterBinding.ensureInitialized();
  
  await Supabase.initialize(
    url: 'https://xyz.supabase.co',
    anonKey: 'your_anon_key',
  );

  // 1. Configure the auto-token refresher
  await TraceletSupabase.configureTokenRefresh(anonKey: 'your_anon_key');

  // 2. Build the HTTP Config pointing to your Supabase RPC
  final httpConfig = TraceletSupabase.buildHttpConfig(
    supabaseUrl: 'https://xyz.supabase.co',
    anonKey: 'your_anon_key',
    rpcFunction: 'insert_tracelet_locations',
  );

  // 3. Start Tracelet
  await Tracelet.ready(Config(
    http: httpConfig,
  ));
}

🛠 Customizing the Payload (Route Context)

If you want to inject custom data (like a driver_id or trip_id) into every location point dynamically, use the Tracelet.setRouteContext() API in Dart:

await Tracelet.setRouteContext(RouteContext(
  taskId: 'order_123',
  custom: {'trip_id': 'trip_456'},
));

The route context data travels with the location row through the SQLite queue and is included natively in the Supabase REST payload.
