# simple_logger

Provides super simple APIs for logging. The log also includes caller info by setting includeCallerInfo to true. On Android Studio, jump to caller info by clicking the log.

## Usage

```dart
// Singleton (factory)
final logger = SimpleLogger();

// Printed without called location
logger.info('Hello info!');
// -> 👻 INFO  2018-12-16 21:46:20.092695 [caller info not available] Hello info!

// Printed function which returns object
logger.info(() => 'Hello info!');
// -> 👻 INFO  2018-12-16 21:46:20.092695 [caller info not available] Hello info!

logger.setLevel(Level.WARNING);

// Not printed
logger.info('Hello info!');

// Printed
logger.warning('Hello warning!');
// -> ⚠️ WARNING  2018-12-16 21:46:20.101114 [caller info not available] Hello warning!

logger.shout('Hello shout!');
// -> 😡 SHOUT  2018-12-16 21:46:20.101308 [caller info not available] Hello shout!

logger.setLevel(
  Level.INFO,
  // Includes  caller info, but this is expensive.
  includeCallerInfo: true,
);

// Printed with called location
logger.info('Hello info!');
// -> 👻 INFO  2018-12-16 21:50:03.562583 [example/simple_logger_example.dart 29:10 in main] Hello info!

// Customize level prefix
logger.levelPrefixes = {};
logger.info('Hello info!');
// -> INFO  2018-12-16 21:50:03.562583 [example/simple_logger_example.dart 29:10 in main] Hello info!

logger.formatter = (info) => 'Customized output: (${info.message})';
logger.info('Hello info!');
// -> Customized output: (Hello info!)

logger.onLogged = (info) => print('Insert your logic with $info');
logger.info('Hello info!');
// -> Customized output: (Hello info!)
// -> Insert your logic with Instance of 'LogInfo'
```
