📒 Usage

1️⃣ Basic Usage with TarsierLogger

The TarsierLogger class is used for structured logging. You can log messages with different levels, such as info, success, and error, along with optional tags.

import 'package:tarsier_logger/tarsier_logger.dart';

final logger = TarsierLogger();

logger.i('Application Started');
logger.s('Operation completed successfully');
logger.w('Warning: Low memory');
logger.e('Error occurred', StackTrace.current);

Static Logging

For a quick and convenient way to log messages, use the static wrapper:

import 'package:tarsier_logger/tarsier_logger.dart';

TarsierLogger.info('Application Started');
TarsierLogger.success('Operation completed successfully');
TarsierLogger.warning('Warning: Low memory');
TarsierLogger.error('Error occurred', StackTrace.current);

2️⃣ Using Console for Simplified Logging

The Console class mimics the console used in other programming languages and provides a simplified approach to logging. You can use Console methods like log, info, success, and more, without needing to instantiate the logger.

import 'package:tarsier_logger/tarsier_logger.dart';

// Using Console (similar to other programming languages' console)
Console.info('Application Started');
Console.success('Operation completed successfully');
Console.warning('Warning: Low memory');
Console.error('Error occurred', StackTrace.current);

Console.i('Application Started');
Console.s('Operation completed successfully');
Console.w('Warning: Low memory');
Console.e('Error occurred', StackTrace.current);

3️⃣Logging Functions: printError, printWarning, printInfo, and More

If you prefer something similar to the default print() function, this is a good alternative as it adds color-coding and structured formatting to your logs.

• printError: Logs an error message in red with an optional tag and icon (⛔).
• printWarning: Logs a warning message in yellow with an optional tag and icon (⚡).
• printInfo: Logs an informational message in blue with an optional tag and icon (💡).
• printSuccess: Logs a success message in green with an optional tag and icon (✅).
• printVerbose: Logs a verbose message in cyan with an optional tag and icon (🚀).

4️⃣ Customizing Logs with Tags and Icons

You can customize the tags and icons in the log messages:

TarsierLogger.info('Application Started', 'app');
TarsierLogger.success('Operation completed successfully', 'operation', '✅');

printError('APP', 'Critical error occurred!', '⚠️');
printWarning('APP', 'Low disk space', '💾');

This allows for flexibility in how you format and style your log messages, improving the readability of logs in different environments.
