Do you heard about Flutter? No? It’s fine. This article is for you and for all the Flutter beginners. This Flutter Tutorial is for Introduction to Flutter Programming and In the next article you can follow Dart Programming Language. So why we wasting our time. Let’s get into the article.
Mobile App Development Frameworks
As you know, there 3 type to create Mobile Application.
To create that kind of Apps, you need a Programming Language or a Frameworks or a Libraries. Here is some examples for Frameworks/Libraries.
Cross Platform App development techniques
The frameworks are the most important driving tools for building any mobile or web application. But for every project has a different kind of requirement and so the choice of the framework must be made carefully. It means we have to choose a Framework according to the requirements.
The main advantage is “write once, Deploy Everywhere”. It means you can deploy your App in both iOS and Android or Windows may be using your one code. Some time back developing and maintaining the same app for both iOS and Android is a tedious task. Facebook is the company that start the lead to do this. They used react native to do this write once, deploy everywhere.
Cross-platform apps are comparatively less performant but are cost effective. So startups and small businesses go for cross-platform app development much more easily than large enterprises.
Now let’s get in back to Flutter Tutorial.
What is Flutter?
Flutter is a SDK released by Google. This is free and open source and Google Mobile UI framework that provides a fast and expressive way for developers to build native apps. As I mentioned in above this framework also allows the developers to create apps for IOS & Android, using a single code base. Flutter was released in 2017.
Why this Google Flutter?
The biggest selling point of Flutter is that once you develop an app it runs on both Android and IOS, write once deploy Everywhere, and flutter is backed by Google.
For the fast development we can use Flutter. Flutter engineered for high development velocity. Hot reload allows to change the code and see it come to life is less than a second without losing the state of the app. Hot reloads means Same as the web, just hit a refresh and your codes also refresh.
This is a single language for layout and backend. Because Android has separate layout and Java/Kotlin files, we need to get references for views and then alter them in the backend files. In the Android Development we need to develop backend as well. Flutter uses a single language(Dart) for design as well as backend and uses a reactive framework.
Most Flexible and attractive UIs are in flutter. I mean we can develop expensive and flexible UIs using flutter with most attractive animations.
The app will look the same for older devices also. There are no additional costs for supporting older devices. Flutter runs on android Jelly Bean or newer. as well as iOS 8 or newer.
How is Flutter/Dart “transformed” to a Native App?
Why Flutter different from React Native?
Some components are adaptive automatically in react native. In flutter, No- adaptive. need to be configured manually. When we discuss about the development speed in React Native, we can make an app with a very less turnaround time. In flutter, Not much than React Native.
When we consider about the UI components and Documentation in React Native, OS native components and very smooth documentation. In flutter, they have Proprietary widgets and Disorganized documentation. Both provide Hot reloading.
But when we consider about the Native Performance Flutter is better than React Native.
What are the companies that is using Flutter
- Google. Of course.
- Google Ads

Framework Architecture – Introduction to Flutter Programming
- Dart Platform
Dart is a language uniquely optimized for client-side development for web and
mobile. Dart is AOT (Ahead Of Time) compiled to fast, predictable, native code, which
allows almost all of Flutter to be written in Dart. This not only makes Flutter fast, virtually everything (including all the widgets) can be customized
- Flutter Engine
Flutter Engine takes core technologies. One is Skia. Skia is a 2D graphics rendering library. Other technology is Dart. use for VM for a garbage-collected object Oriented Language.
- Foundation Library
The Foundation library, written in Dart, provides basic classes and functions which are used to construct applications using Flutter, such as APIs to communicate with the engine.
In flutter, every element is a widget. Actually whole page is a widget. The rough equivalent to a View is a Widget and they are fast, pretty and customizable. Because Flutter includes the Material Components library. These are widgets that implement the Material Design guidelines. Material Design is a flexible design system optimized for all platforms, including iOS.
