如何通过构造函数将数据传递给flutter中的Card list？我已经尝试了这些东西，结果和想要的是附加的

class CardData {
  final String title;
  final String description;

  CardData(this.title, this.description);
}

import 'package:flutter/material.dart';

class CardListPage extends StatelessWidget {
  final List<CardData> cards;

  CardListPage(this.cards);

  @override
  Widget build(BuildContext context) {
    return Scaffold(
      appBar: AppBar(
        title: Text('Card List'),
      ),
      body: ListView.builder(
        itemCount: cards.length,
        itemBuilder: (context, index) {
          return Card(
            child: ListTile(
              title: Text(cards[index].title),
              subtitle: Text(cards[index].description),
            ),
          );
        },
      ),
    );
  }
}

import 'package:flutter/material.dart';

class HomePage extends StatelessWidget {
  @override
  Widget build(BuildContext context) {
    List<CardData> cards = [
      CardData('Card 1', 'Description 1'),
      CardData('Card 2', 'Description 2'),
      CardData('Card 3', 'Description 3'),
    ];

    return Scaffold(
      appBar: AppBar(
        title: Text('Home'),
      ),
      body: Center(
        child: RaisedButton(
          child: Text('Open Card List'),
          onPressed: () {
            Navigator.push(
              context,
              MaterialPageRoute(
                builder: (context) => CardListPage(cards),
              ),
            );
          },
        ),
      ),
    );
  }
}
