Usage

1. Add the dependency to your pubspec.yaml file
   Recommend to use command line:

   flutter pub add cherrilog
   

   With Dart

   dart pub add cherrilog
   

2. Import library

   import 'package:cherrilog/cherrilog.dart';
   

3. Initialize cherrilog

   CherriLog.init(
     options: CherriOptions()
       ..logLevelRange = CherriLogLevelRanges.all
       ..useBuffer = false,
   ).logTo(CherriConsole()); // Use `CherriFile()` instead of `CherriConsole` if you want to log to file system
   

4. Call log methods

   debug('This is a debug message');
   info('This is an info message');
   warning('This is a warning message');
   error('Something went wrong');
   fatal('Oh oh :(');
   

Log levels

Cherrilog provides a CherriLogLevel class to support custom level, and below is the default instances:

• CherriLogLevel.fatal: Fatal errors
• CherriLogLevel.error: Errors
• CherriLogLevel.warning: Warnings
• CherriLogLevel.info: Information messages
• CherriLogLevel.debug: Debug messages

And you will also see nether and upperBond, these two instances is to help with comparison, don't use them directly.

You can find some predefined log level ranges in CherriLogLevelRanges class.

Timestamp Patterns

We offer some preset timestamp formats with in formatter/timestamp.dart.

You can also use your own format.

Output
