Masamune Model Firebase Remote Config

Usage

Installation

1. Add the package to your project.

flutter pub add masamune_model_firebase_remote_config

Run flutter pub get after editing pubspec.yaml manually.

Setup

2. Register the adapter with your Masamune model configuration. Provide default values and fetch intervals.

// lib/main.dart

import 'package:masamune_model_firebase_remote_config/masamune_model_firebase_remote_config.dart';

final modelAdapter = FirebaseRemoteConfigModelAdapter(
  options: DefaultFirebaseOptions.currentPlatform,  // Firebase config
  initialValue: {
    "feature_enabled": false,
    "api_endpoint": "https://api.example.com",
    "max_items": 10,
  },
  minimumFetchInterval: Duration(minutes: 30),  // Cache duration
);

void main() {
  runMasamuneApp(
    appRef: appRef,
    modelAdapter: modelAdapter,
    (appRef, _) => MasamuneApp(
      appRef: appRef,
      home: HomePage(),
    ),
  );
}

Load Remote Config Values

3. Load the remote config as a Masamune model. Fetching is handled automatically through fetchAndActivate() each time the adapter loads.

class MyPage extends PageScopedWidget {
  @override
  Widget build(BuildContext context, PageRef ref) {
    // Load remote config as a document
    final config = ref.app.model(
      FirebaseRemoteConfigModel.document(),
    )..load();

    return Scaffold(
      body: Column(
        children: [
          // Access config values
          Text("Feature: ${config.value.get<bool>("feature_enabled")}"),
          Text("Endpoint: ${config.value.get<String>("api_endpoint")}"),
          Text("Max Items: ${config.value.get<int>("max_items")}"),
        ],
      ),
    );
  }
}

Important Notes

Read-Only: Only read operations are supported. Saving or deleting documents with this adapter throws UnsupportedError. Use Firebase Console or the Remote Config REST API to update values.

Caching: The adapter respects minimumFetchInterval. Values are cached and won't be refetched until the interval expires.

Default Values: Provide initialValue to ensure your app works even when remote config is unavailable.

Firebase Console Setup

1. Go to Firebase Console → Remote Config
2. Add parameters matching your initialValue keys
3. Set values for different conditions (e.g., by platform, version, or user segment)
4. Publish your changes
