Log4Dart

Logging library with multiple appenders, configurable formatting and log tracing.

Getting Started

1. Add the folowing to your pubspec.yaml and run pub install

	dependencies:
	  log4dart: any

2. Add log4dart to some code and run it

	import "package:log4dart/log4dart.dart";
	
	main() {
		var myClass = new MyClass();
		myClass.someMethod();
	}
		
	class MyClass {
		static final _logger = LoggerFactory.getLoggerFor(MyClass);
	
		someMethod() {
			_logger.info("a info message");
			// :
			_logger.warnFormat("%s %s", ["message", "formatting"]);
		}
	}

Creating Loggers

Log4Dart is split in multiple libraries so it can run on both servers and in browsers.

// for client side logging (works both on the VM and when compiled to JS)
import "package:log4dart/log4dart.dart";

// for VM logging, allows you to log to files (does not compile to JS) 
import "package:log4dart/log4dart_vm.dart";

When you want to retrieve a logger instance you can do it in one of two ways

1. LoggerFactory.getLoggerFor(MyClass) - logger with the fully qualified name of MyClass
2. LoggerFactory.getLogger("MyClass") - logger with the name "MyClass"

Where the qualified name is the library name and type name concatenated together.
