Snug Logger 🛋️

A colorful, structured logger for Flutter apps.

Snug Logger helps you:

• read logs faster with clean formatting and colors
• log by intent (debug, info, error, production)
• inspect Dio network traffic with optional cURL output
• get readable stack traces for error debugging

Install

dependencies:
  snug_logger: ^1.0.11

flutter pub get

Quick Start

import 'package:snug_logger/snug_logger.dart';

snugLog('App started', logType: LogType.info);
snugLog('Fetching user profile', logType: LogType.debug);

Error Logging with Stack Trace

try {
  throw Exception('Something went wrong');
} catch (error, stackTrace) {
  snugLog(
    error,
    logType: LogType.error,
    stackTrace: stackTrace,
  );
}

Network Logging (Dio)

_dio.interceptors.add(
  SnugDioLogger(
    requestHeaders: true,
    requestData: true,
    responseHeaders: true,
    responseData: true,
    showCurl: true,
    logPrint: (object) => debugPrint(object.toString()),
  ),
);

When showCurl: true is enabled, Snug Logger prints reproducible cURL commands so you can quickly share failing requests with backend teams.

What You Can Configure

• requestHeaders: include request headers
• requestData: include request body/query
• responseHeaders: include response headers
• responseData: include response body
• showCurl: print cURL command for each request

Advanced Stack Trace Utilities

If you want direct control over stack trace formatting:

final formatted = StackTraceFormatter.format(stackTrace);
final terse = StackTraceFormatter.formatTerse(stackTrace);
final snug = StackTraceFormatter.formatForSnugLogger(stackTrace);
