It all starts with an app. Isn't it? At least, this is what the business world seems to suggest in the third decade of the 21st century. Mobile applications are at the center stage of almost everything the world perceives as "up and running."
With over 230 billion app downloads in 2021, there's hardly a territory left where mobile applications are not influencing our planet and its inhabitants in one way or the other.
We are looking to build an app in an environment heavily impacted by mobile technologies. When we talk of technologies impacting the mobile application development market, Flutter comes up as a force to reckon with in no uncertain terms.
Flutter is an open-source, cross-platform mobile app development framework that facilitates programmers to build native-looking iOS and Android applications. Businesses can hire flutter developers to develop and launch mobile apps that align with their business goals.
Why choose Flutter?
- Save time and money
- Enhanced performance
- 'Hot reload' feature
- Cross-platform app development
- Open source
- Google's brand value
- community support
- Flutter enjoys the trust of some of the finest players in the market
Now, here's how you can write your first Flutter app:
Step 1
First things first! You need to install Flutter and have a suitable editor (Android Studio) or XCode) established. After this, you are good to go to create a new Flutter project.
Step 2
Now, open the terminal window and go to the directory where you wish to create your project.
Step 3
Create your Flutter app based on templates as you build a Flutter project called startup_namer like follows
$ flutter create startup_namer
$ cd startup_namer
Please note that you will mostly edit lib/main.dart
Step 4
Next, replace whatever the contents are in lib/main.dart. Erase all the code from lib/main.dart and replace the same with the code given below.
import 'package:flutter/material.dart';
void main() {
runApp(const MyApp());
}
class MyApp extends StatelessWidget {
const MyApp({super.key});
@override
Widget build(BuildContext context) {
return MaterialApp(
title: 'Welcome to Flutter',
home: Scaffold(
appBar: AppBar(
title: const Text('Welcome to Flutter'),
),
body: const Center(
child: Text('Hello World'),
),
),
);
}
}
The screen should welcome you with "Hello World" at the center.
Step 5
This step lets you use an open-source package named 'english_words' consisting of some utility functions and English words.
-Add the 'english_words' as a dependency of your app with the help of the following code
$ flutter pub add english_words
Resolving dependencies...
async 2.8.1 (2.8.2 available)
characters 1.1.0 (1.2.0 available)
+ english_words 4.0.0
matcher 0.12.10 (0.12.11 available)
test_api 0.4.2 (0.4.5 available)
vector_math 2.1.0 (2.1.1 available)
Changed 1 dependency!
-In lib/main.dart, go ahead and import the new package with the following code
import 'package:english_words/english_words.dart'; // Add this line.
import 'package:flutter/material.dart';
Step 6
The next step is to use the english_words package to render the text rather than using "Hello World".
Step 7
Following the previous step, add a stateful widget.
Step 8
In the next step, you should create an infinite-scrolling ListView.
Wrapping up
These steps are listed to help you build your first Flutter app. You can also hire dedicated developers in USA or anywhere according to your geographical feasibility to develop stunning Flutter applications.
