Introduction

Everything in Flutter is a widget. Plugins, also known as dependencies, are tools that are often used in Flutter to make code operate more efficiently and quickly. Flutter has many plugins, one of which is the analog_clock plugin, which may be used to create an analog clock.

Let’s learn how to create an analog clock along with the help of a code example.

Adding Dependencies

The plugins can be added to flutter in several steps:-

Step1: From the project folder, open the pubspec.yaml file.

Step2: In the pubspec.yaml file, type analog_clock: under dependencies section. The code will look like this.

dependencies:
    flutter:
sdk: flutter
    analog_clock:

Step3: Click on the Pub Get button at the top of Android Studio.

Step4: The console message "Process finished with exit code 0" indicates that the dependency was successfully added.

Step5: In the final step, import the plugin by adding the “import ‘package:analog_clock/analog_clock.dart’;” to the top of the main.dart file.

Now we have successfully added the analog_clock plugin to our app. It's time to learn about that plugin, its features, and how it helps to create the analog clock.

The analog_clock plugin

The analog_clock plugin contains numerous parameters that play an important part in the clock's design. These characteristics can be changed at any time, making it more user-friendly.

The main parameters of the analog_clock plugin are:-

1.) datetime: It sets the time from which the clock needs to be run.

2.) showNumbers: It hides the numbers near the ticks by using the false condition.

3.) showTicks: The measurements available in the clock's boundaries are referred to as ticks. The false condition can be used to hide these ticks and vice versa.

4.) isLive: It lets the clock run once the time is set.

5.) decoration: This option helps create a clock in flutter using the available decorating widgets.

6.) textScaleFactor: It helps in the customization of the digital clock's size and the numbers near the ticks.

7.) height, width: These parameters are used to set the height and width of the clock.

Stateful and Stateless Widgets

There are two types of widgets in flutter: stateless and stateful widgets.

Static widgets are created with the stateless widget, while dynamic widgets are created with the stateful widget. We must utilize the stateful widget to generate the analog clock because time is a dynamic aspect. As a result, a state in which the clock runs is required, and the AnalogClock function is called to use the parameters to construct the required clock.

Source Code

The source code to create the clock is given below:-

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

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

class MyApp extends StatefulWidget {
@override
_MyAppState createState() => _MyAppState();
}

class _MyAppState extends State<MyApp> {
@override
Widget build(BuildContext context) => MaterialApp(
home: Scaffold(
appBar: AppBar(
backgroundColor: Colors.blue[700],
title: Text('Coding Ninjas'),
),
backgroundColor: Colors.green,
body: Center(
child: AnalogClock(
decoration: BoxDecoration(
border: Border.all(width: 3.0, color: Colors.black),
color: Colors.black,
shape: BoxShape.circle),
width: 300.0,
isLive: true,
hourHandColor: Colors.white,
minuteHandColor: Colors.white,
showSecondHand: true,
numberColor: Colors.white,
showNumbers: true,
textScaleFactor: 1.5,
showTicks: true,
showDigitalClock: true,
digitalClockColor: Colors.white,
datetime: DateTime(2022, 5, 12, 10, 11, 0),
),
),
),
);
}

Frequently asked questions

What are Plugins in Flutter?

Plugins, also known as dependencies, are tools that are often used in Flutter to make code operate more efficiently and quickly.

Which plugin is used to create an analog clock in Flutter?

The analog_clock plugin is used to create an analog clock in Flutter.

What are widgets in Flutter?

In Flutter, a widget is a user interface component that impacts and controls the app's view and interface. It is an immutable description of a user interface component that contains widget-created visuals, text, shapes, and animations.

What are the two main types of widgets in Flutter?

Widgets in flutter are divided into two main categories:-

1.) Stateless Widget

2.) Stateful Widget
