logzio: remove 'time', 'level' and 'loggerName' from 'message'

[deezaster]

the fields 'time', 'level' and 'loggerName' are already sent individually to logz.io. Therefore they are not needed in 'message'.

sb.write('${rec.time} ${rec.level.name} ${rec.loggerName} - ${rec.message}');

You have control over the log formatter by overriding the default one.

Here is how I initialize LogzIoApiAppender:

final logzIoApiSender = LogzIoApiAppender(
      formatter: BlockFormatter.formatRecord(_logFormatter),
      apiToken: _logzIoToken,
      labels: {
        'os': Platform.operatingSystem,
        'os_version': Platform.operatingSystemVersion,
        'locale': Platform.localeName,
        'build_mode': kDebugMode ? 'debug' : 'release',
      },
      type: 'flutter',
    );

and that BlockFormatter.formatRecord(_logFormatter) is taking a private function which can be defined as whatever you need. Here is what I'm using:

String _logFormatter(LogRecord rec) {
    final sb = StringBuffer();
    sb.write('${rec.level.name} - ${rec.message}');
    if (rec.error != null) {
      sb.writeln();
      sb.write('### ${rec.error?.runtimeType}: ');
      sb.write(rec.error);
    }
    // ignore: avoid_as
    final stackTrace = rec.stackTrace ?? (rec.error is Error ? (rec.error as Error).stackTrace : null);
    if (stackTrace != null) {
      sb.writeln();
      sb.write(stackTrace);
    }
    return sb.toString();
  }

Is this what you needed? Doh, just realized this is a really old issue.
