Flutter日期处理插件date_utility的使用

Flutter日期处理插件date_utility的使用

一个用于获取日期方法的项目。

特性

• 获取日期功能

示例

1. 将毫秒转换为日期

示例 1:

DateUtility.millisecondToDate(1715365800000, formatPattern: 'yyyy-MM-dd',);    // 2024-05-11

示例 2:

DateUtility.millisecondToDate(1715365800000, formatPattern: 'd MMM yyyy',);    // 11 May 2024

2. 将日期转换为毫秒

示例 1:

DateUtility.dateToMillisecond('2024-05-11');    // 1715365800000

示例 2:

DateUtility.dateToMillisecond('11 May 2024');    // 1715365800000

3. 更改日期格式

示例 1:

DateUtility.changeDateFormat('2024-05-11', '11 May 2024');    // 2024-05-11 转换为 11 May 2024

示例 2:

DateUtility.changeDateFormat('11 May 2024', '2024-05-11');    // 11 May 2024 转换为 2024-05-11

4. 计算天数差

示例 1:

DateUtility.daysBetween('2024-05-10', '2024-05-11');    // 1 天

示例 2:

DateUtility.daysBetweenWithMilliSecond(1715279400000, 1715365800000);    // 1 天

5. 时间差（时间之前）

示例 1:

DateUtility.timeAgoSinceDate('2024-05-10', numericDates: true,);    // 1 天前

示例 2:

DateUtility.timeAgoSinceMilliseconds(1715279400000, numericDates: true,);    // 1 天前

以下是一个完整的Flutter应用示例，展示如何使用date_utility插件进行日期处理：

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

void main() {
  runApp(MyApp());
}

class MyApp extends StatelessWidget {
  [@override](/user/override)

      home: Scaffold(
        appBar: AppBar(
          title: Text("Date Utility Demo"),
        ),
        body: DateUtilityDemo(),
      ),
    );
  }
}

class DateUtilityDemo extends StatefulWidget {
  [@override](/user/override)
  _DateUtilityDemoState createState() => _DateUtilityDemoState();
}

class _DateUtilityDemoState extends State<DateUtilityDemo> {
  String _result = "";

  void _convertMillisecondToDate() {
    setState(() {
      _result = DateUtility.millisecondToDate(1715365800000, formatPattern: 'yyyy-MM-dd');
    });
  }

  void _convertDateToMillisecond() {
    setState(() {
      _result = DateUtility.dateToMillisecond('2024-05-11').toString();
    });
  }

  void _changeDateFormat() {
    setState(() {
      _result = DateUtility.changeDateFormat('2024-05-11', '11 May 2024');
    });
  }

  void _daysBetween() {
    setState(() {
      _result = DateUtility.daysBetween('2024-05-10', '2024-05-11');
    });
  }

  void _timeAgoSinceDate() {
    setState(() {
      _result = DateUtility.timeAgoSinceDate('2024-05-10', numericDates: true);
    });
  }

          SizedBox(height: 16),
          ElevatedButton(
            onPressed: _daysBetween,
            child: Text("Days Between Dates"),
          ),
          SizedBox(height: 16),
          ElevatedButton(
            onPressed: _timeAgoSinceDate,
            child: Text("Time Ago Since Date"),
          ),
