flutter_basics

A lightweight, production-safe utility package for Flutter applications providing structured logging, file-based log storage, and manual log upload support.

Designed and maintained by Mobigic Technology.

✨ Features

✅ Production-safe logger (MobigicLogger)

🧾 Supports log levels: trace, debug, info, warning, error, fatal

🚫 Automatically disables console logs in release mode

💾 Persistent file-based logging using LogService

☁️ Manual log upload support

🧹 Clear logs after successful upload

📱 Works with Flutter mobile apps (Android & iOS)

🔄 Useful for crash tracking & in-app update debugging

📦 Installation

Add the dependency in pubspec.yaml:

dependencies: flutter_basics: ^latest

Run:

flutter pub get

📥 Import import 'package:flutter_basics/flutter_basics.dart';

🚀 Usage Console Logging (MobigicLogger) MobigicLogger.debug("Debug message"); MobigicLogger.info("Info message"); MobigicLogger.warning("Warning message"); MobigicLogger.error("Error message");

Log objects easily:

MobigicLogger.info({ "status": "success", "version": 1, });

🧱 Log Levels MobigicLogger.trace("Trace log"); MobigicLogger.debug("Debug log"); MobigicLogger.info("Info log"); MobigicLogger.warning("Warning log"); MobigicLogger.error("Error log"); MobigicLogger.fatal( "Fatal error", error: error, stackTrace: stackTrace, );

🔒 Production Safety

✅ Logs print only in debug/profile

🚫 No console logs in release builds

⚙️ No manual flags required

💾 File-Based Logging (LogService)

LogService allows you to persist logs into a local file for later upload or debugging.

Write Logs to File await LogService.writeLog("Home screen opened"); await LogService.writeLog("User clicked submit button"); await LogService.writeLog("CRASH ERROR: API failed");

Each entry is saved with a timestamp:

2025-12-16T10:30:15.432 -> Home screen opened

☁️ Upload Logs

Useful for Report Issue, Support, or Crash Recovery flows.

Future

try { await LogService.writeLog("Manual log upload initiated by user");

await MobigicHelper.uploadFile(file);

// Clear logs after successful upload
await file.writeAsString("");

MobigicLogger.info("Logs uploaded & cleared successfully");

} catch (e) { await LogService.writeLog("Upload failed: $e"); MobigicLogger.error("Log upload failed", error: e); } }
