thin_logger

Description:

thin logger

A minimal logger class, suitable mostly for console utilities rather than enterprise-grade applications.
Features #
Comprises a single class that, by default, allows just three levels of the output: quiet (none), normal (data, errors and info) and verbose (maximum).
Usage #
The usage is pretty straightforward. Please see the sample code below or in the example folder of the GitHub repository.
import 'package:thin_logger/thin_logger.dart';

/// Return the logger level based on CLI option
///
int parseLevel(String optLevel) {
switch (optLevel) {
case '-q':
return Logger.levelQuiet;
case '-v':
return Logger.levelVerbose;
default:
return Logger.levelDefault;
}
}

/// The application entry point
///
void main(List<String> args) {
// Initializing the logger object
//
var level = parseLevel(args.isEmpty ? '' : args[0]);
var logger = Logger(level);

// Printing various-level data
//
logger.out('Plain data');
logger.error('ERR');
logger.info('INF');

// This is the most expensive call, as every string will be interpolated
// (substituted with the values like 'abc $d ef ${g.h}') unconditionally,
// and the respective Logger method will be called
//
if (logger.isVerbose) {
logger.verbose('VRB');
}
