Flutter票务展示插件ticketview的使用
Flutter票务展示插件ticketview的使用
简介
TicketViewFlutter 是一个用于 Flutter 的简单且可定制的票务/收据视图插件。该插件完全由 Dart 编写。
动机
我在开发我的 Flutter 应用程序时,需要一些简洁的票务/收据视图组件。
开始使用
安装
将此依赖项添加到您的 pubspec.yaml
文件中:
dependencies:
ticketview: ^1.0.0
然后运行以下命令以安装依赖项:
flutter pub get
导入
在您的项目中导入此库:
import 'package:ticketview/ticketview.dart';
使用方法
默认票务视图
您可以直接在 Widget 树中使用默认的票务视图:
TicketView(
child: Container(),
)
自定义收据视图
以下是一个自定义收据视图的示例:
TicketView(
backgroundPadding: EdgeInsets.symmetric(vertical: 0, horizontal: 20),
backgroundColor: Color(0xFF8F1299),
contentPadding: EdgeInsets.symmetric(vertical: 24, horizontal: 0),
drawArc: false,
triangleAxis: Axis.vertical,
borderRadius: 6,
drawDivider: true,
trianglePos: .5,
child: Container(),
)
自定义选项
根据您的需求,可以调整以下属性来定制票务视图的外观:
属性名称 | 类型 | 描述 |
---|---|---|
backgroundColor |
Color | 票务视图的背景颜色 |
contentBackgroundColor |
Color | 票务视图内容区域的颜色 |
示例代码
