Customization

This logger has simple settings that can change output

1. Filtering

  final logger = TalkerLogger(
    settings: const TalkerLoggerSettings(
      // Set current logging level
      level: LogLevel.critical,
    ),
  );

  // Works as before
  logger.critical('critical');
  // Does not work
  logger.info('info');

Result

2. Formating

Create your own LoggerFormatter implementation For example - ColoredLoggerFormatter that makes messages only with colors

class ColoredLoggerFormatter implements LoggerFormatter {
  @override
  String fmt(LogDetails details, TalkerLoggerSettings settings) {
    final msg = details.message?.toString() ?? '';
    final coloredMsg =
        msg.split('\n').map((e) => details.pen.write(e)).toList().join('\n');
    return coloredMsg;
  }
}

And add formatter for TalkerLogger constructor

  final logger = TalkerLogger(
    formatter: ColoredLoggerFormatter(),
  );

  logger.debug('debug');
  logger.info('info');
  logger.warning('warning');
  logger.error('error');

Result

Or you can make simple customization with default formatters

  final logger = TalkerLogger(
    settings: TalkerLoggerSettings(
      colors: {
        LogLevel.critical: AnsiPen()..yellow(),
        LogLevel.error: AnsiPen()..yellow(),
        LogLevel.info: AnsiPen()..yellow(),
        LogLevel.fine: AnsiPen()..yellow(),
      },
      maxLineWidth: 20,
      lineSymbol: '#',
      enableColors: true,
    ),
  );

  logger.info('info');
  logger.critical('critical');
  logger.error('error');
  logger.fine('fine');

Result
