What is Flutter? Here is everything you should know in 2021

Are you looking to learn Flutter app development courses?
Wait, First, read the article carefully after you will clear all your doubts that which course is best for you in android app development.

When we start any app development journey, we are confused regarding which programming language we have to start. The most common language to start is Java, Kotlin, C, C++, Python, and many more in the universe of coding.
Usually, the goal is to develop an app that is Android or iOS according to the requirements. All language has several functions, and all functions have different properties.

Are you a newbie or an experienced fellow who is curious to learn any programming language?

When WordPress came into the web market. It was new, and now from WordPress, there are above 45% of website are developed and are using their CMS. The one famous website that uses CMS is Udemy (for verifying you can visit w3.org), an internet organization. Now everyone can easily make the website by drag and drop.

The app market is increasing amazingly.

In the world, the most using operating system is Android. Statistics proved by many surveys that nearly 80% of the global market users are using Android smartphone.
Android has a considerable Market share, and now many companies are focusing on Android apps because the market is rising very fast. So Android becomes the locus of attraction for all businesses. Companies trying to give the best future to the users through a smartphone. Releasing better features the businesses building a strong relationship with their audience.

Android vs IOS

So are you thinking the best is the android app development courses, not the iOS app development courses? No, in Android, the competition is very high as compare to the iOS app development. They both have high-paying jobs.

I have an idea from that you can develop an android app, and an iOS app from one programming language, and the language is a dart.
Yes, I am talking about Flutter- The growing Native app development.
From Flutter, you can develop an android app, iOS app, and web app.
Imagine how you feel when you write a single code and are using it in different operating systems. The Flutter saves time and gives a fast app.

I develop an app and try Flutter very well, and I am happy to create a flutter app.

Revolution of app development through Flutter

In March 2015, the first native app framework came into the market that was React native. React Native is an open-source framework and was developed by Facebook.
The React native using as a programming language is javascript. Yes, from javascript, you can develop a web, Android, and iOS app.
And later, in the year 2017, Flutter was introduced by Google as a cross-platform. It also has the same features as react-native.
The main advantage of Flutter is the speed App, a lot of animation, and has an enormous widget that we can’t expect in React native and other app developing platforms. So Flutter is the future thinking app development.

What is Flutter

Flutter is an open-source UI framework created by Google in 2017. It is easy to develop a native app for Android, iOS, and the web app from a single code base. From which the single code base we use to create a programming language called Dart.

History of Flutter

In 2015, the first version of Flutter was released as the code name ‘Sky’ that runs on the Android operating system, later at the end of the 2018 Flutter event, was released Flutter 1.0, which was the first stable version. After releasing Flutter 1.0, the flutter community is continuously growing.

Why Flutter

Before 2015, we have to learn different languages for different operating systems to create a mobile app. We have to learn Java for making an Android app or for an iOS app have to learn Swift. So to develop an App is very complicated and time-consuming.
Today there are several frameworks have introduced for developing multiple operating systems. This type of platform is called a cross-platform UI framework.

Flutter framework design

The flutter framework containing four components are as follows:

  • Dart platform: As we discuss that flutter applications are written in the Dart programming language.
  • Flutter engine: flutter engines are written in C, C++, Dart and are using Google skin graphic library.
  • Foundation library: The flutter library is using Dart. So from that, we can communicate with different APIs.
  • Widgets build specialization: The flutter framework containing the specific widget on the particular platform. The material design implements Android design by the Google guidelines, and the Cupertino design implements Apple design by the IOS guidelines.

Features of Flutter

  • A single code base for multiple operating systems
  • Good layout methodology.
  • Work well with firebase as a backend.
  • Use Dart programming language, which is very easy to pick up.
  • Use a rich set of material designs.
  • High-performance mobile application.
  • Great documentation to read on the flutter website.

Benefits of a flutter

Flutter fulfills all the requirements an app developer wants. There are no doubts about the Flutter. Here some advantages are below:

  • Flutter uses Dart programming language that was very easy to learn and Dart has many packages that extend the capabilities of the application.
  • It using a single codebase for multiple operating systems and expands other platforms (desktop) in the future.
  • Flutter saves money and time because Flutter using a single codebase, so it has less testing work.
  • Google flutter has a hot reload future that means when we do changes in the code, that show instant results.
  • Flutter is an open-source technology that means we don’t want to pay a single amount for developing an application.
  • has a broad community, and Google is also promoting that means to have a bright future.

Disadvantages of Flutter

As we know, a coin has to side that means Flutter has advantages but also have disadvantages:
For developing an application using Flutter need to learn a new programming language known as Dart (very easy to learn).
The Flutter is a comparatively new framework that needs huge libraries for that flutter community already working.

I think when we move to 2023, the Flutter doesn’t have any disadvantages. The flutter community will solve all the problems that befell.

How to start learning Flutter

For learning flutter, you require a basic programming skill in any language. Or if you don’t know, then you can learn in just one week. after you have to learn the dart language from which the Flutter works.
Dart, You can learn around two weeks quickly. Let’s the final step is to start to go to the YouTube channel and ask us how to learn Flutter we guide you from start to end.

Before starting flutter

  • Good understanding of programming principles
  • Class
  • Functions and methods
  • Asynchronous code
  • API

Hell World flutter example

import 'package:flutter/material.dart';

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

class MyApp extends StatelessWidget {
  @override
  Widget build(BuildContext context) {
    return MaterialApp(
      title: 'Welcome to Flutter',
      home: Scaffold(
        appBar: AppBar(
          title: Text('Welcome to Flutter'),
        ),
        body: Center(
          child: Text('Hello World'),
        ),
      ),
    );
  }
}
