Masamune Logger Firebase

Usage

Installation

Add the package to your project.

flutter pub add masamune_logger_firebase

Run flutter pub get after editing pubspec.yaml manually.

Register the Adapter

Set up FirebaseLoggerMasamuneAdapter before running the app. This adapter provides both logging (FirebaseLoggerAdapter) and integration with Firebase services.

// lib/adapter.dart

import 'package:masamune/masamune.dart';
import 'package:masamune_logger_firebase/masamune_logger_firebase.dart';

/// Logger adapters used by the application.
final loggerAdapters = <LoggerAdapter>[
  const FirebaseLoggerAdapter(),  // Add Firebase logger
];

/// Masamune adapters used by the application.
final masamuneAdapters = <MasamuneAdapter>[
  const UniversalMasamuneAdapter(),
  
  const FirebaseLoggerMasamuneAdapter(
    options: DefaultFirebaseOptions.currentPlatform,  // From firebase_options.dart
  ),
];

Key Features:

• Initializes Firebase automatically
• Attaches Crashlytics error handling to FlutterError and PlatformDispatcher
• Adds navigation observers for automatic screen tracking
• Exposes FirebaseAnalytics, FirebaseCrashlytics, and FirebasePerformance instances

Access the adapter via FirebaseLoggerMasamuneAdapter.primary.

Logging Events

Use the logger API to send events to Firebase Analytics. The package provides pre-built loggable classes for common events.

Sign-In Events:

// Get the logger from your controller or page
final logger = LoggerAdapter.primary.first;

// Log user sign-in
await logger.send(const FirebaseAnalyticsSignInLoggable(
  userId: "user_123",
  providerId: "google.com",
));

// Log user registration
await logger.send(const FirebaseAnalyticsRegisterLoggable(
  userId: "user_456",
));

Purchase Events:

await logger.send(const FirebaseAnalyticsPurchasedLoggable(
  transactionId: "order-001",
  currency: "USD",
  price: 9.99,
  products: [
    FirebaseAnalyticsPurchaseProduct(
      id: "sku-1",
      name: "Premium Plan",
      price: 9.99,
      quantity: 1,
    ),
  ],
));

Tutorial Events:

// Tutorial started
await logger.send(const FirebaseAnalyticsTutorialStartLoggable());

// Tutorial completed
await logger.send(const FirebaseAnalyticsTutorialEndLoggable());

Performance Monitoring

Use performance traces to measure operation durations:

final logger = LoggerAdapter.primary.first;

// Start a trace
final trace = logger.trace("load_profile");
await trace.start();

// Execute the operation you want to measure
await loadUserProfile();

// Stop the trace
await trace.stop();

Crashlytics

Crash reports are captured automatically when the adapter is registered. The adapter hooks into FlutterError.onError and PlatformDispatcher.onError.

Test Crashlytics Integration:

// Force a test crash (only for testing!)
final logger = FirebaseLoggerAdapter.primary;
await logger.crash();

Manual Error Reporting:

try {
  // Your code
} catch (e, stackTrace) {
  await FirebaseCrashlytics.instance.recordError(e, stackTrace);
}
