Flutter文本滑动浏览插件SwipeThroughText的使用
预览
限制
目前该插件仅支持单行文本。溢出的文本将被裁剪并在末尾添加省略号 ...
。这是一个暂时的限制,欢迎贡献以增加对多行文本的支持。
开始使用
安装
在你的 pubspec.yaml
文件中添加以下依赖:
dependencies:
swipe_through_text: ^0.0.4
然后在终端运行 flutter pub get
。
使用
首先,导入该包到你的Dart代码中:
import 'package:swipe_through_text/swipe_through_text.dart';
使用 SwipeThroughText
小部件时,可以传递必需的参数(如 text
和 textStyle
)和可选参数(如 strikethroughColor
、strikethroughLineHeight
、swipeThreshold
、onSwipeComplete
、onSwipeCancel
和 dashArray
)。
SwipeThroughText(
text: 'Swipe me!',
textStyle: TextStyle(fontSize: 24),
strikethroughColor: Colors.red,
strikethroughLineHeight: 4,
swipeThreshold: 0.8,
onSwipeComplete: (fraction) {
// 当滑动完成时执行的操作
},
onSwipeCancel: (fraction) {
// 当滑动取消时执行的操作
},
)
你还可以通过 dashArray
参数自定义删除线。dashArray
接受一个双精度值列表,用于确定删除线中虚线和间隙的长度。例如,[10, 5]
将创建一个虚线删除线,其中虚线长度为10像素,间隙长度为5像素。
示例
以下是一个完整的示例,展示了如何使用 SwipeThroughText
小部件:
import 'package:flutter/material.dart';
import 'package:swipe_through_text/swipe_through_text.dart';
void main() {
runApp(const MyApp());
}
class MyApp extends StatelessWidget {
const MyApp({super.key});
[@override](/user/override)
Widget build(BuildContext context) {
return MaterialApp(
debugShowCheckedModeBanner: false,
title: 'SwipeThroughText Demo',
home: Scaffold(
appBar: AppBar(
title: const Text('SwipeThroughText Demo'),
),
body: Container(

child: Column(
mainAxisAlignment: MainAxisAlignment.center,
children: [
SwipeThroughText(
text: 'Swipe Through me! limited to 1 line',
textStyle: const TextStyle(fontSize: 24),
strikethroughColor: Colors.red,
strikethroughLineHeight: 4,
swipeThreshold: 0.5,
onSwipeComplete: (fraction) {
debugPrint('Swipe completed at $fraction');
},
onSwipeCancel: (fraction) {
debugPrint('Swipe cancelled at $fraction');
},
dashArray: const [], // 对于虚线使用:const [10, 5],
),
const SizedBox(
height: 10,
),
SwipeThroughText(
text: 'Swipe Through me! limited to 1 line',
textStyle: const TextStyle(fontSize: 24),
strikethroughColor: Colors.green,
strikethroughLineHeight: 4,
swipeThreshold: 0.5,
onSwipeComplete: (fraction) {
debugPrint('Swipe completed at $fraction');
},
onSwipeCancel: (fraction) {
debugPrint('Swipe cancelled at $fraction');
},
dashArray: const [10, 5],
),
const SizedBox(
height: 10,
),
SwipeThroughText(
text: 'Swipe Through me! limited to 1 line',
textStyle: const TextStyle(fontSize: 24),
strikethroughColor: Colors.purple,
strikethroughLineHeight: 4,
swipeThreshold: 0.5,
onSwipeComplete: (fraction) {
debugPrint('Swipe completed at $fraction');
},
onSwipeCancel: (fraction) {
debugPrint('Swipe cancelled at $fraction');
},
dashArray: const [], // 对于虚线使用:const [10, 5],
),
],
),
),
),
);
