Flutter波斯日历插件flutter_persian_calendar的使用
Flutter Persian Calendar插件提供了一个简单且可定制的波斯(Jalali)日历小部件,可以轻松集成到你的Flutter项目中。该插件基于shamsi_date
包。
功能
- 日期过滤:可以通过设置起始和结束日期来过滤显示的日期。
- 自定义选项:可以根据应用程序的主题自定义日历的外观。
使用方法
添加依赖
在你的pubspec.yaml
文件中添加以下依赖:
dependencies:
flutter_persian_calendar: ^0.0.2
然后运行以下命令以获取依赖项:
flutter pub get
导入包
在你的库文件中导入该包:
import 'package:flutter_persian_calendar/flutter_persian_calendar.dart';
示例代码
创建一个按钮让用户选择日期
ElevatedButton(
onPressed: () {
// 显示带有日历的对话框
showDialog(
context: context,
builder: (context) {
return Dialog(
child: shamsiDateCalendarWidget(context, calendarDarkTheme),
);
},
);
},
child: const Text('Select Date'),
);
// 可以创建一个基础的日历小部件以展示不同的主题
PersianCalendar shamsiDateCalendarWidget(
BuildContext context,
PersianCalendarTheme calendarTheme,
) {
return PersianCalendar(
calendarHeight: 376, // 设置日历小部件的高度为376
calendarWidth: 360, // 设置日历小部件的宽度为360
selectedDate: selectedDate, // 初始化时显示的选中日期
onDateChanged: (newDate) {
setState(() {
selectedDate = newDate; // 更新选中的日期
});
},
onConfirmButtonPressed: () {
Navigator.pop(context); // 用户点击确认按钮时关闭对话框
},
calendarStartDate: Jalali(1300, 4, 12), // 日历从1300/4/12开始显示
calendarEndDate: Jalali(1402, 7, 10), // 日历直到1402/7/10结束显示
calendarTheme: calendarTheme, // 设置传递过来的主题
);
}
自定义主题
你可以通过修改PersianCalendarTheme
中的颜色、文本样式、高度和宽度等来自定义日历的外观。下面是一个自定义的浅色主题示例:
PersianCalendarTheme lightTheme = PersianCalendarTheme(
backgroundColor: const Color(0XFFEDF2F4),
selectedColor: const Color(0XFFEF233C),
headerBackgroundColor: const Color(0XFF8D99AE),
textStyle: const TextStyle(
fontSize: 14,
color: Colors.black,
),
selectedItemTextStyle: const TextStyle(
fontSize: 14,
color: Color(0XFFF2F2F2),
),
confirmButtonTextStyle: const TextStyle(
fontSize: 14,
color: Color(0XFFF2F2F2),
),
headerTextStyle: const TextStyle(
fontSize: 14,
color: Colors.black,
),
);

当然,以下是如何在Flutter项目中使用flutter_persian_calendar
插件的示例代码。这个插件允许你在Flutter应用中集成波斯(伊朗)日历。
1. 添加依赖
首先,你需要在pubspec.yaml
文件中添加flutter_persian_calendar
的依赖:
dependencies:
flutter:
sdk: flutter
flutter_persian_calendar: ^x.y.z # 请替换为最新版本号
然后运行以下命令来安装依赖:
flutter pub get
2. 导入插件
在你的Dart文件中导入插件:
import 'package:flutter_persian_calendar/flutter_persian_calendar.dart';
3. 使用波斯日历
下面是一个完整的示例,展示如何在Flutter应用中使用波斯日历:
import 'package:flutter/material.dart';
import 'package:flutter_persian_calendar/flutter_persian_calendar.dart';
void main() {
runApp(MyApp());
}
class MyApp extends StatelessWidget {
@override
Widget build(BuildContext context) {
return MaterialApp(
title: 'Flutter Persian Calendar Example',
theme: ThemeData(
primarySwatch: Colors.blue,
),
home: PersianCalendarScreen(),
);
}
}
class PersianCalendarScreen extends StatefulWidget {
@override
_PersianCalendarScreenState createState() => _PersianCalendarScreenState();
}
class _PersianCalendarScreenState extends State<PersianCalendarScreen> {
PersianCalendarController? _controller;
DateTime? _selectedDate;
@override
void initState() {
super.initState();
_controller = PersianCalendarController();
// 设置初始选中的日期为当前日期
_controller?.setSelectedDate(DateTime.now());
}
@override
void dispose() {
_controller?.dispose();
super.dispose();
}
void _onDateSelected(DateTime date) {
setState(() {
_selectedDate = date;
});
}
@override
Widget build(BuildContext context) {
return Scaffold(
appBar: AppBar(
title: Text('Flutter Persian Calendar'),
),
body: Padding(
padding: const EdgeInsets.all(16.0),
