Simple, powerful, efficient, and easily comprehensible framework for mobile app development in DART- Google’s own language, yes, it exists!

And the name of the framework is Flutter!

Using this popular app framework, you can develop a mobile application of top quality and high performance across mobile operating systems- Android, iOS, Windows, and more.

In an area where you have to deal with complex structures, codes, and stuff, Flutter is a boon to overcome the complexity. It renders the UI directly in the operating system’s canvas and not through the native framework.

So, if you are a startup and need an app with good market speed, Flutter is for you! Apart from this, there are other aspects of this amazing framework that are out of people’s eyes.

In this blog, we will discuss different aspects of Flutter that will give you an idea of how it fits your app requirements.
Let’s begin!

Introduced by Google, Flutter is an open-source framework for native mobile app development for cross-platform app development for different operating systems such as Android and iOS.

It is comparatively a new framework, which was released in May 2017. Flutter combines high performance with ease of development without compromising on the visual consistency between platforms.

Since it is completely free and allows using one codebase to create two different apps, it has gained popularity with React Native on GitHub and Stack Overflow.

It has two crucial parts that include:

  • An SDK (Software Development Kit), which is a collection of tools that include the ones that you can use to compile your codes into native machine code. All the tools are used in mobile app development.
  • Another important part of the Flutter framework is the UI library which is based on widgets. It includes a collection of UI elements that can be reused and personalized according to the needs. The UI elements could be buttons, text inputs, sliders, and more.

Apart from this, there are a few features that Flutter has to offer. Some of them are mentioned below:

  • Flutter comes with a modern and reactive framework
  • It uses the easy language DART for programming
  • You can use the same codebase for two different apps
  • Helps in the fast development of apps
  • Comes with an attractive and fluid user interface
  • It has a huge catalog of widgets
  • Using Flutter, you can run the same UI for multiple platforms
  • It is a simple and high-performance framework


Now, let’s see how this entire framework works.

The Working Pattern of Flutter


When it comes to working on Flutter, you must know the most crucial thing that everything is a widget! But, what is a widget? So, before you dive deep into the working of Flutter, let’s understand what a widget is and how it fits in Flutter framework and app development.

Widget is the innumerable number of descriptions for each element in the user interface. Now, widgets can be inflated into elements that manage the underlying render tree. It holds the configuration that you provide for the UI.

However, Flutter uses its own rendering engine to render each view component. This is how developers are able to build Flutter-based apps with characteristics similar to native apps. Here the Flutter builds the UI to reflect the state of the app. When the data on the app is changed the UI is redrawn and the Flutter constructs the new instance of the widget.

The three most important elements of Flutter are Widgets, Elements, and Render Objects. We have already discussed what a Widget is, let’s have quick details about Elements and Render Objects in Flutter. Elements are the ones that hold the slot in the UI hierarchy, manage the reference and tree. A render object is something that knows about the layout and points to the UI.

The widgets are configured and mounted which means rendered where a widget tree and element tree are created. Under the hood, the render tree is the third tree that uses the rendered object which computes and implements the basic layout and protocols.

The best example of a mobile application developed using Flutter is KlasterMe. It is a content sharing platform, where people can make pages, create and share a variety of content ranging from images to articles. The design is attractive and the user interface is simple where the content posting process is easy.

How is Flutter in Terms of Performance?


Flutter applications are usually observed to be equally performant as any other high-performance app. The biggest reason is that it is fast, offers seamless integration with mobile OS platforms.

The framework is fast where the rendering runs 60 fps and 120 fps for capable devices. The higher is the number of fps, the smoother would be the animation and transitions. Not only it is fast, but it also has numerous benefits to offer that we have discussed in the section below. Let’s have a look at each one of them.

Flutter is known for fast development owing to its beautiful and customizable widgets that help deliver outstanding mobile applications which are highly performant. This way, it fulfills all the custom requirements. Besides this, Flutter offers numerous benefits out of which some are mentioned below −

  • Flutter lets you extend the capabilities of your application, owing to a large repository of software packages that comes with Dart.
  • Developers can use just a single code base for both applications (both Android and iOS platforms). Also, it appears that Flutter may be extended to other platforms as well in the future.
  • You need less testing for Flutter mobile apps as compared to other mobile development frameworks. The reason is the usage of a single code base, so when we write automated tests once for both platforms, it is completely fine and sufficient to get it tested once.
  • As discussed in the section above, Flutter is apt for fast development especially when you need an app with a quick time to market. Also, the customization capability and extensibility make it powerful compared to other cross-platform mobile app development frameworks.
  • Another best thing that comes with Flutter is the full control over the widgets and the layout that developers can exercise.
  • Flutter offers an inventory of implicit UI segments that you can change easily, which makes the process of modification easier. Using it, you can customize the app and offer a great UI experience to your customers.
  • Also, Flutter offers a huge library of software packages and developer tools, with amazing hot reload.

After getting an idea of how Flutter could be beneficial for your business, let’s see what all important things you should consider while using it.
