使用

安装

在pubspec.yaml文件中添加依赖：

dependencies:
  nepali_calendar_flutter: latest

然后在项目中导入它：

import 'package:nepali_calendar_flutter/nepali_calendar_flutter.dart';

创建并使用NepaliCalendarController，实例化CleanNepaliCalendar小部件：

class MyApp extends StatelessWidget {
  final NepaliCalendarController _calendarController = NepaliCalendarController();

  [@override](/user/override)
  void initState() {
    super.initState();
    _calendarController = NepaliCalendarController();
  }

  [@override](/user/override)
  Widget build(BuildContext context) {
    return NepaliCalendar(
      controller: _calendarController,
      onDaySelected: (day) {
        print(day.toString());
      },
    );
  }
}

示例代码

以下是完整的示例代码：

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

void main() => runApp(MyApp());

class MyApp extends StatelessWidget {
  [@override](/user/override)
  Widget build(BuildContext context) {
    return MaterialApp(
      title: 'Clean Nepali Calendar Demo',
      theme: ThemeData(
        primarySwatch: Colors.blue,
      ),
      home: HomePage(),
    );
  }
}

class HomePage extends StatelessWidget {
  final NepaliCalendarController _nepaliCalendarController = NepaliCalendarController();

  [@override](/user/override)
  Widget build(BuildContext context) {
    final NepaliDateTime first = NepaliDateTime(2075, 5);
    final NepaliDateTime last = NepaliDateTime(2079, 3);
    return Scaffold(
      appBar: AppBar(
