A simple logging package that works everywhere - Web, Android, iOS, Linux, macOS, and Windows.

Features

• 🌐 Works on all platforms
• 📝 Saves logs to files (native platforms only)
• 🔄 Automatic file rotation when size limit reached
• 📍 Shows where each log was called from
• ⚙️ Easy to customize

Installation

dependencies:
  flutter_multiplatform_logger: ^1.0.0

Quick Start

import 'package:flutter_multiplatform_logger/flutter_multiplatform_logger.dart';

void main() async {
  WidgetsFlutterBinding.ensureInitialized();
  
  // Start the logger (IMPORTANT: use await!)
  await FlutterMultiplatformLogger.init();
  
  // Use it
  final logger = Logger('MyApp');
  logger.info('App started!');
  
  runApp(MyApp());
}

Custom Settings

await FlutterMultiplatformLogger.init(
  maxFileSizeBytes: 5 * 1024 * 1024,  // 5MB per file
  maxBackupCount: 20,                  // Keep 20 old files
  logDirName: 'my_logs',              // Custom folder name
);

Platform Differences

• Native (Android/iOS/Desktop): Saves logs to files with rotation
• Web: Only prints to console (browsers don't allow file access)
