I have a static clock (isLive: false) that displays a time. Then, as a result of user action, it has to display a different time. This does not work. Instead of displaying the second time, the AnalogClock widget starts displaying the current system time.

Minimal example to demonstrate the problem:

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

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

class MyApp extends StatelessWidget {
  const MyApp({Key? key}) : super(key: key);

  @override
  Widget build(BuildContext context) {
    return MaterialApp(
      title: 'Flutter Demo',
      theme: ThemeData(
        primarySwatch: Colors.blue,
      ),
      home: const MyHomePage(title: 'Flutter Demo Home Page'),
    );
  }
}

class MyHomePage extends StatefulWidget {
  const MyHomePage({Key? key, required this.title}) : super(key: key);
  final String title;

  @override
  State<MyHomePage> createState() => _MyHomePageState();
}

class _MyHomePageState extends State<MyHomePage> {
  DateTime time = DateTime(2022, 1, 1, 12, 30, 0);

  @override
  Widget build(BuildContext context) {
    return Scaffold(
      appBar: AppBar(
        title: Text(widget.title),
      ),
      body: Center(
        child: AnalogClock(
          isLive: false,
          datetime: time,
        ),
      ),
      floatingActionButton: FloatingActionButton(
        onPressed: () => setState(() => {
          time = time.add(const Duration(minutes: 15))
        }),
        tooltip: 'Increment',
        child: const Icon(Icons.add),
      ), // This trailing comma makes auto-formatting nicer for build methods.
    );
  }
}

When tapping the (+) button, the clock should show 12:45. Instead it shows the current time.

Motivation

This plugin is beautiful! It deserves to be updated to the nowadays standards.

Description

• Added support to nullsafety
• Changed dart minimum version to 2.12
• Changed example project to nullsafety too
• Edited the changelog

Checks

• [x] Did you test your feature?
• [x] Did it worked both on Android and iOS?

Currently when you turn on the digital clock it will always display in military time format. I made the clock default to standard 12-hour format with the option to use military time.

If you are hard set on military time being the default I can make 12-hour format the extra option instead.

Let me know if you have any questions.

I commented the "void main() => runApp(MyApp());" line and uncommented the "void main() => runDemo();" line and built the project on andriod The app is displaying nothing but a white screen!

Widget build(BuildContext context) {
    //DateTime d = DateTime.now();
    DateTime d = DateTime(2020,4,1,1,15,15,15,123);
    return Column(
      children: <Widget>[
        AnalogClock(
          datetime: d,
           isLive: true,
         ),
       ],
    );
...

I used another datetime either fetching from server or creating any DateTime the clock don't run Have you ever seen ?

The plugin analog_clock uses a deprecated version of the Android embedding. To avoid unexpected runtime failures, or future build failures, try to see if this plugin supports the Android V2 embedding. Otherwise, consider removing it since a future release of Flutter will remove these deprecated APIs. If you are plugin author, take a look at the docs for migrating the plugin to the V2 embedding: https://flutter.dev/go/android-plugin-migration.

When changing the DateTime that is passed into the AnalogClock Widget based on some event the clock isn't updating on the device. Having taken a look at the code, I believe this is because you haven't overridden the didUpdateWidget method in the _AnalogClockState class.

I believe you need a method like

@override
  void didUpdateWidget(AnalogClock oldWidget) {
    super.didUpdateWidget(oldWidget);
    
    if(!widget.isLive && widget.datetime != oldWidget.datetime) {
      datetime = widget.datetime;
    }
  }

I have added a feature to add all the hour numbers in the analog clock and fixed kotlin version. Also, I added extra padding accidentally in the first commit which I have removed.
