simplest_logger

A lightweight, opinionated, colorful logging utility for Dart applications that provides an easy-to-use interface for console logging with minimal configuration.

• Colored console output (info: green, warning: yellow, debug: blue, error: red)
• Automatic timestamps for all log messages
• Automatic class name labeling
• Simple mixin for quick integration
• Runtime-configurable logging levels (both globally and per-instance)
• Global configuration support
• Zero dependencies

Usage

The most basic usage is to use the SimplestLogger class directly:

final logger = SimplestLogger('MyClass', LogLevel.all);
logger.info('Application started');    // Green output
logger.warning('Cache miss');          // Yellow output
logger.debug('Processing request');    // Blue output
logger.error('Connection failed');     // Red output

For a more integrated approach, you can use the SimplestLoggerMixin mixin:

class MyService with SimplestLoggerMixin {
  void doSomething() {
    logger.info('Operation started');
  }
}

Controlling log levels

You have three ways to control logging behavior:

1. Globally using SimplestLoggerConfig:

// Turn off all logging across the app
SimplestLoggerConfig.globalLogLevel = LogLevel.off;

// Make loggers ignore global settings (use their individual settings)
SimplestLoggerConfig.respectGlobalLogLevel = false;

2. Per instance when creating a SimplestLogger:

final logger = SimplestLogger('MyClass', LogLevel.off);

3. Per mixin by setting the logLevel property:

class ProductionService with SimplestLoggerMixin {
    ProductionService() {
        // Disable logging for this service
        logLevel = LogLevel.off;
    }
}

By default:

• Global logging is enabled (LogLevel.all)
• Global settings are respected (respectGlobalLogLevel = true)
• Individual loggers can override the global setting if respectGlobalLogLevel is set to false
