Answer 1

使用答案并稍作更改：-

您可以尝试以下方法：

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



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

class TabBarDemo extends StatelessWidget {
 @override
Widget build(BuildContext context) {
DateTime now = DateTime.now();
String formattedDate = DateFormat('kk:mm:ss \n EEE d MMM').format(now);
return MaterialApp(
  home: DefaultTabController(
    length: 3,
    child: Scaffold(
      appBar: AppBar(
        bottom: TabBar(
          tabs: [
            Tab(icon: Icon(Icons.access_alarm),text: "Alarm",),
            Tab(icon: Icon(Icons.access_time),text:"Clock" ,),
            Tab(icon: Icon(Icons.timer),text:"Timer"),
          ],
        ),
        title: Text('Tabs Demo'),backgroundColor: Colors.black,
      ),
      body: TabBarView(
        children: [
          Icon(Icons.access_alarm),
          Center(child: Text(formattedDate,textAlign: TextAlign.center,style: new TextStyle(fontWeight: FontWeight.bold,fontSize: 25.0),)),
          Icon(Icons.timer),
        ],
      ),
    ),
  ),
);
}
}

应该给你这个：

Answer 2

获取AM/PM格式的当前时间。

dynamic currentTime = DateFormat.jm().format(DateTime.now());

Answer 3

在颤振 1.20 中：

DateTime now = DateTime.now();

print(now.hour.toString() + ":" + now.minute.toString() + ":" + now.second.toString());

Answer 4

var now = DateTime.now();
var formatterDate = DateFormat('dd/MM/yy');
var formatterTime = DateFormat('kk:mm');
String actualDate = formatterDate.format(now);
String actualTime = formatterTime.format(now);
