# Belatuk Petty Logging  [](https://dart.dev/null-safety) [](https://gitter.im/angel_dart/discussion) [](https://github.com/dart-backend/belatuk-common-utilities/blob/main/packages/pretty_logging/LICENSE) **Replacement of `package:pretty_logging` with breaking changes to support NNBD.** Standalone helper for colorful logging output, using pkg:io AnsiCode. ## Installation In your `pubspec.yaml`: ```yaml dependencies: belatuk_pretty_logging: ^5.0.0 ``` ## Usage Basic usage is very simple: ```dart myLogger.onRecord.listen(prettyLog); ``` However, you can conditionally pass logic to omit printing an error, provide colors, or to provide a custom print function: ```dart var pretty = prettyLog( logColorChooser: (_) => red, printFunction: stderr.writeln, omitError: (r) { var err = r.error; return err is AngelHttpException && err.statusCode != 500; }, ); myLogger.onRecord.listen(pretty); ```
