Boa tarde, pessoal.

Estou com uma dúvida. Para não ficar repetindo o tamanho do quadrado colorido (height e width), implementei que o tamanho é passado via parâmetros através da classe MyApp. Essa é uma boa prática para se adotar?

import 'package:flutter/material.dart';

void main() {
  runApp(const MyApp(height: 100, width: 100));
}

class MyApp extends StatelessWidget {
  final double height;
  final double width;
  const MyApp({super.key, required this.height, required this.width});

  @override
  Widget build(BuildContext context) {
    return MaterialApp(
      title: 'Flutter Demo',
      theme: ThemeData(
        colorScheme: ColorScheme.fromSeed(seedColor: Colors.deepPurple),
        useMaterial3: true,
      ),
      home: Container(
        color: Colors.black,
        child: Column(
          mainAxisAlignment: MainAxisAlignment.spaceEvenly,
          children: [
            Row(
              mainAxisAlignment: MainAxisAlignment.spaceEvenly,
              children: [
                Container(color: Colors.red, height: height, width: width,),
                Container(color: Colors.orange, height: height, width: width,),
                Container(color: Colors.yellow, height: height, width: width,),
              ],
            ),
            Row(
              mainAxisAlignment: MainAxisAlignment.spaceEvenly,
              children: [
                Container(color: Colors.green, height: height, width: width,),
                Container(color: Colors.cyan, height: height, width: width,),
                Container(color: Colors.blue, height: height, width: width,),
              ],
            ),
            Row(
              mainAxisAlignment: MainAxisAlignment.spaceEvenly,
              children: [
                Container(color: Colors.purple, height: height, width: width,),
                Container(color: Colors.pink, height: height, width: width,),
                Container(color: Colors.white, height: height, width: width,),
              ],
            )
          ],
        ),
      ),
    );
  }
}
