示例代码

下面是一个完整的示例代码,展示了如何使用 dynamic_timeline_tile_flutter 插件来创建一个动态的时间线展示。

import 'package:flutter/material.dart';
import 'package:dynamic_timeline_tile_flutter/dynamic_timeline_tile.dart';

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

class MyApp extends StatelessWidget {
  [@override](/user/override)
  Widget build(BuildContext context) {
    return MaterialApp(
      title: 'Flutter Dynamic Timeline',
      theme: ThemeData(
        primarySwatch: Colors.blue,
      ),
      home: const TestDynamicTimelineTile(),
    );
  }
}

class TestDynamicTimelineTile extends StatefulWidget {
  const TestDynamicTimelineTile({Key? key}) : super(key: key);

  [@override](/user/override)
  _TestDynamicTimelineTileState createState() => _TestDynamicTimelineTileState();
}

class _TestDynamicTimelineTileState extends State<TestDynamicTimelineTile> {
  final List<EventCard> events = [
    EventCard(
      cardColor: Colors.grey.shade300,
      child: CustomEventTile(
        icon: MdiIcons.bookOutline,
        title: 'Mathematics Exam',
        description: 'Exam will start from 11:30 and ends in 3:15',
      ),
    ),
    EventCard(
      cardColor: Colors.grey.shade300,
      child: CustomEventTile(
        icon: MdiIcons.bookOutline,
        title: 'General Science Exam',
        description: 'Exam will start from 11:30 and ends in 3:15. Students are informed to bring their project work along with the materials needed.',
      ),
    ),
    EventCard(
      cardColor: Colors.grey.shade300,
      child: CustomEventTile(
        icon: MdiIcons.bookOutline,
        title: 'Physics Exam',
        description: 'Exam will start from 9:00 and end in 12:00. Please bring a scientific calculator.',
      ),
    ),
    EventCard(
      cardColor: Colors.grey.shade300,
      child: CustomEventTile(
        icon: MdiIcons.bookOutline,
        title: 'Foreign Language Exam',
        description: 'Exam will start from 8:00 and end in 11:00. Bilingual dictionaries permitted.',
      ),
    ),
    EventCard(
      cardColor: Colors.grey.shade300,
      child: CustomEventTile(
        icon: MdiIcons.bookOutline,
        title: 'Literature Exam',
        description: 'Exam will start from 11:00 and end in 2:00. Bring novels for reference.',
      ),
    ),
  ];

  [@override](/user/override)
  Widget build(BuildContext context) {
    return Scaffold(
      appBar: AppBar(
        title: Text('Dynamic Timeline'),
      ),
      body: MultiDynamicTimelineTile(
        eventsList: events,
      ),
    );
  }
}

当然,以下是一个关于如何在Flutter项目中使用dynamic_timeline_tile_flutter插件来展示动态时间线的示例代码。这个插件允许你创建具有动态更新能力的时间线视图。

首先,确保你的pubspec.yaml文件中已经添加了dynamic_timeline_tile_flutter依赖:

dependencies:
  flutter:
    sdk: flutter
  dynamic_timeline_tile_flutter: ^最新版本号  # 请替换为最新的版本号

然后,运行flutter pub get来安装依赖。

接下来,在你的Flutter项目中,你可以按照以下步骤使用dynamic_timeline_tile_flutter插件:

  1. 导入插件

在你的Dart文件中导入插件:

import 'package:dynamic_timeline_tile_flutter/dynamic_timeline_tile_flutter.dart';
  1. 定义时间线数据

你需要定义一些时间线数据,这些数据将用于填充时间线视图。这里我们创建一个简单的示例数据列表:

List<TimelineEvent> events = [
  TimelineEvent(
    title: 'Event 1',
    description: 'This is the description of Event 1',
    dateTime: DateTime.now().subtract(Duration(days: 3)),
    icon: Icons.event,
  ),
  TimelineEvent(
    title: 'Event 2',
    description: 'This is the description of Event 2',
    dateTime: DateTime.now().subtract(Duration(days: 1)),
    icon: Icons.today,
  ),
  TimelineEvent(
    title: 'Event 3',
    description: 'This is the description of Event 3',
    dateTime: DateTime.now(),
    icon: Icons.announcement,
  ),
];
  1. 构建时间线视图

使用DynamicTimelineTile组件来展示时间线:

import 'package:flutter/material.dart';
import 'package:dynamic_timeline_tile_flutter/dynamic_timeline_tile_flutter.dart';

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

class MyApp extends StatelessWidget {
  @override
  Widget build(BuildContext context) {
    return MaterialApp(
      title: 'Dynamic Timeline Demo',
      theme: ThemeData(
        primarySwatch: Colors.blue,
      ),
      home: Scaffold(
        appBar: AppBar(
          title: Text('Dynamic Timeline Demo'),
        ),
        body: Padding(
          padding: const EdgeInsets.all(16.0),
          child: DynamicTimelineTile(
            events: events,
            alignment: TimelineAlignment.center,
            indicatorStyle: IndicatorStyle(
              activeColor: Colors.blue,
              inactiveColor: Colors.grey,
              indicatorSize: 12.0,
            ),
            connectorStyle: ConnectorStyle(
              color: Colors.grey[300]!,
              width: 2.0,
            ),
            eventBuilder: (context, event) {
              return Padding(
                padding: const EdgeInsets.all(8.0),
                child: Column(
                  crossAxisAlignment: CrossAxisAlignment.start,
                  children: [
                    Row(
                      children: [
                        Icon(event.icon, color: Colors.blue),
                        SizedBox(width: 8),
                        Text(event.title, style: TextStyle(fontSize: 18, fontWeight: FontWeight.bold)),
                      ],
                    ),
                    SizedBox(height: 4),
                    Text(event.description, style: TextStyle(fontSize: 14)),
                    SizedBox(height: 8),
                    Text(
                      DateFormat('yyyy-MM-dd HH:mm').format(event.dateTime),
                      style: TextStyle(fontSize: 12, color: Colors.grey),
                    ),
                  ],
                ),
              );
            },
          ),
        ),
      ),
    );
  }
}

在这个示例中,我们:

  • 使用了DynamicTimelineTile组件来显示时间线。
  • 通过events属性传递了时间线事件列表。
  • 自定义了时间线事件的显示样式,包括指示器样式、连接器样式和事件构建器。

DateFormat类来自intl包,如果你还没有添加这个包,请在pubspec.yaml中添加:

dependencies:
  intl: ^0.17.0  # 请替换为最新的版本号

然后运行flutter pub get

这个示例展示了如何使用dynamic_timeline_tile_flutter插件来创建一个简单但功能强大的动态时间线视图。你可以根据需要进一步自定义和扩展这个示例。
