ログから「flutter:」消せる？

import 'package:flutter/foundation.dart';
import 'package:flutter/material.dart';
import 'package:flutter/services.dart';

void main() {
  // ログ出力のフォーマットを設定する
  if (!kReleaseMode) {
    SystemChannels.platform.setMethodCallHandler((MethodCall call) async {
      if (call.method == 'log') {
        // ログのメッセージ文字列から "flutter:" を削除する
        final dynamic arguments = call.arguments;
        print('${arguments['level']} ${arguments['message'].toString().replaceAll('flutter:', '')}');
      }
    });
  }
  runApp(MyApp());
}

class MyApp extends StatelessWidget {
  @override
  Widget build(BuildContext context) {
    return MaterialApp(
      title: 'My Flutter App',
      home: Scaffold(
        appBar: AppBar(
          title: Text('My Flutter App'),
        ),
        body: Center(
          child: Text('Hello, World!'),
        ),
      ),
    );
  }
}
