Flutter列表项转换为卡片插件listtile_to_card的使用

特性

screenshot1

根据官方的 Material 3: Card，列表项和卡片都是展示列表项的好方式。

这个包提供了通过 MediaQuery.of(context).size 将小部件转换为 ListTile 或 Card 的功能。

使用方法

ListTileToCard(
    breakWidth: 400,
    axisDirection: AxisDirection.left,
    cardMargin: const EdgeInsets.all(12),
    cardElevation: 6,
    cardShape: RoundedRectangleBorder(
    borderRadius: BorderRadius.circular(16),
    ),
    mainAxisAlignment: MainAxisAlignment.end,
    crossAxisAlignment: CrossAxisAlignment.end,
    listTile: ListTile(
    leading: const Icon(Icons.start),
    trailing: const Icon(Icons.exit_to_app_outlined),
    title: Text('Width: ${size.width}, Heigth: ${size.height}'),
    onTap: _incrementCounter,
    ),
)

示例代码

import 'dart:developer';

import 'package:flutter/material.dart';
// import 'package:listtile_to_card/listtile_to_card.dart';
import 'listtile.dart';

void main() {
  runApp(const MyApp());
}

class MyApp extends StatelessWidget {
  const MyApp({super.key});

  // This widget is the root of your application.
  [@override](/user/override)
  Widget build(BuildContext context) {
    return MaterialApp(
      title: 'ListTile to Card',
      theme: ThemeData(
        colorScheme: ColorScheme.fromSeed(seedColor: Colors.deepPurple),
        useMaterial3: true,
      ),
      home: const MyHomePage(title: 'ListTile to Card'),
    );
  }
}

class MyHomePage extends StatefulWidget {
  const MyHomePage({required this.title, super.key});

  final String title;

  [@override](/user/override)
  State<MyHomePage> createState() => _MyHomePageState();
}

class _MyHomePageState extends State<MyHomePage> {
  ///
  int _counter = 0;

  ///
  void _incrementCounter() {
    setState(() {
      _counter++;
    });
    log(_counter.toString());
  }

  [@override](/user/override)
  Widget build(BuildContext context) {
    final size = MediaQuery.of(context).size;
    // log('Width: ${size.width}');
    // log('Heigth: ${size.height}');
    // log(Theme.of(context).cardTheme.color.toString());

在Flutter中，ListTile 是一个常用的组件，用于在列表中显示单行信息。然而，有时候你可能希望将 ListTile 转换为卡片（Card）形式，以提供更好的视觉效果和交互体验。虽然Flutter没有直接提供 ListTile 转换为 Card 的插件，你可以通过将 ListTile 包装在 Card 组件中来实现这个效果。

使用 Card 包装 ListTile

以下是一个简单的示例，展示了如何将 ListTile 转换为 Card：

import 'package:flutter/material.dart';

void main() {
  runApp(MyApp());
}

class MyApp extends StatelessWidget {
  @override
  Widget build(BuildContext context) {
    return MaterialApp(
      home: Scaffold(
        appBar: AppBar(
          title: Text('ListTile to Card Example'),
        ),
        body: ListView(
          children: <Widget>[
            Card(
              child: ListTile(
                leading: Icon(Icons.album),
                title: Text('Card Title 1'),
                subtitle: Text('This is a subtitle'),
                trailing: Icon(Icons.more_vert),
              ),
            ),
            Card(
              child: ListTile(
                leading: Icon(Icons.album),
                title: Text('Card Title 2'),
                subtitle: Text('This is another subtitle'),
                trailing: Icon(Icons.more_vert),
              ),
            ),
            // Add more cards here
          ],
        ),
      ),
    );
  }
}

解释

  1. Card 组件: Card 是一个 Material Design 卡片组件，通常用于显示一组相关的信息。它可以包含其他组件，如 ListTile、文本、图像等。

  2. ListTile 组件: ListTile 是一个常用的组件，用于在列表中显示单行信息。它包括前导图标 (leading)、标题 (title)、副标题 (subtitle) 和尾部图标 (trailing) 等部分。

  3. 组合使用: 在这个例子中，每个 ListTile 都被包装在一个 Card 组件中，从而实现了 ListTile 到 Card 的转换。

自定义卡片外观

你可以通过设置 Card 的 shape、elevation、color 等属性来自定义卡片的外观。例如：

Card(
  elevation: 5.0,
  shape: RoundedRectangleBorder(
    borderRadius: BorderRadius.circular(10.0),
  ),
  color: Colors.blue[50],
  child: ListTile(
    leading: Icon(Icons.album),
    title: Text('Custom Card'),
    subtitle: Text('This is a custom styled card'),
    trailing: Icon(Icons.more_vert),
  ),
),
