Getting Started with Flutter: A Step-by-Step Tutorial
It later appeared on the developers’ scene as a predictable cross-platform solution for native appearance and performance to create elegant and efficient mobile apps. Discussing its essence, however, no one knows exactly what it — Flutter- is, well, Flutter. So what is special about it that is definitely worth using it for your coming post? In this tutorial, which is a great in depth overview, we will look into the technologies of Flutter development, examine what their features are, their benefits and how they are in the mobile apps development world.

### What is Flutter?

[Flutter is a cross-platform](https://www.addevice.io/blog/flutter-for-cross-platform-development) UI framework developed by the community for Android and iOS. It's a UI software development kit (SDK) by Google. It makes it possible for developers to create applications which can run natively on either mobile, web, or desktop versions of the same application, and all this can be run from the single codebase. Unlike WebView and JavaScript bridge based cross-platform frameworks that depend on them to render UI, Flutter uses a reactive framework that lets the similarity of UI with truly native performance.

_Why Choose Flutter for Cross-Platform Development?_

Building a cross-platform mobile application using Flutter is definitely something an app developer would want to consider doing. The first way Flutter is different from other frameworks is the fast development cycle that literally shows the changes right away after the code is entered to the system thanks to the hot reload feature. This repeated rapid process is a good environment for production and also reduces the time for development.

Another vital aspect of Flutter is that it offers a suite of highly customizable widgets which devs can use to create visual interfaces that look and feel as slick and natural as native apps for each platform. With Flutter, you will not have to concern yourself with providing a user experience that is comparable to those offered by native applications on other platforms whenever you're building cross-platform applications.

_Overview of Flutter's Features and Benefits_

To say that Flutter has a number of features and advantages which makes it a fetish to developers will be an understatement. Some of the key features of Flutter include:

- **Expressive and flexible UI**: Flutter programmers can design any UI design with widget-based architecture integrated into the app. It provides a wide range of customizable widgets.
- **High performance**: Flutter apps are coded in native language, thus, boot times are quick plus the animations occur easily.
- **Access to native features**: Flutter comes with plugins that bridge the gap between the phones' operating systems and the developers code by providing access to phone specific features like camera, geolocation, and sensors.
- **Strong community support**: Developers of Flutter along with others are of great asset to the Flutter community as they are all helpful in finding plugins, packages, and other resources which can even a developer achieve the success.

The nature of what you want to build and your available resources heavily influence what development environment you decide to set up from scratch.
By this time bear in mind that we’ll deal with the Easter eggs of Flutter, and set the development environment. First step to the installation of the Flutter SDK that contains everything you may need to build Flutter apps. 

### Setting Up Your Development Environment

Next, cloning your Flutter SDK is mandatory and you also have to configure the settings of your Integrated Development Environment (IDE). Flutter provides user-friendly tools including the support of Android Studio and VS Code IDEs. If you somehow don’t know the IDE that you’re more familiar with and if you already don’t have the Flutter and Dart plugins installed in it to be able to develop a Flutter application on your chosen IDE.

Lastly, you should get the emulators and physical devices ready for the final app testing in Flutter. These utilities have a Virtual Machine (Android Emulator) or Simulator (iOS Simulator) that inclines in testing apps on a virtual device. Another thing doable for you is establishing a communication link between the simulation machine and operating real devices on your machine.

### Building Your First Flutter App
Now that we have given an overview of everything related to Flutter programming language, it’s now time to start building your first Flutter app. Follow these steps to create a new Flutter project:

- Let's start the coding part with our IDE and create a Flutter-based project.
- Create and locate the name for your Flutter project at your destination.
- Wait for the environment to be set up; dependencies should be installed accordingly.`

A directory structure, with files and folders occupying that, will visualize once your project is resolved successfully. The most vital file in this case is main.dart, and it is where the app's main entry point is based.

Let’s try to write some code to generate "Hello, World!" message in our app. Open main.dart and replace the existing code with the following:

This is a basic Flutter app that makes use of scaffold and an app bar with material design. The text widget displays the words "Hello, World!" centered on the screen. Open the file and run your app by typing command 'flutter run' in your console or IDE.

### Conclusion
In the coaching cycle, we have discussed the key notions of what Flutter is and tools required for the development of an app from scratch to the finish. Flutter is equipped with Cody’s rapid development cycle, an expressive user interface (UI) and performance that comes in-built. This makes it a powerful framework for creating cross-platform mobile applications that have been put to ever changing user needs. Whether you are a beginner or an experienced developer, Flutter is working on providing support for a seamless development which makes you able to transform ideas to reality with simplicity.

Bear in mind that the community of developers, who are gladly willing to be always helpful as you keep paddling with Flutter, is with you every step of the way. Discover the communities by going through forums, communities and working with fellow Flutter fans to derive more from your Flutter quest. Because there are learning curves everywhere, challenges will come with time.

In addition, you can discover various professionals to assist in professional help in the vast online world of experienced developers. In platforms such as Clutch, Goodfirms and developer forums you can find  [Flutter development companies](https://www.addevice.io/blog/10-flutter-app-development-companies) worldwide for creating your application.

Consequently, finally relying upon your new state of knowledge of Flutter, it's time for you to start developing apps which will make users pleased to work with a similar kind of platform.Happy coding!
