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:
- 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';
- 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,
),
];
- 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。
