What is Flutter?

If you don’t know it, you don’t love it, then we have to get to know flutter so that we can get better at writing flutter with love.. hehehe 😀

Creating applications with attractive designs on various platforms is now easier to do. One way is to use Flutter. What is Flutter? Flutter is a kind of framework used to help developers create multiplatform mobile apps.

Many of the world’s largest companies have adopted Flutter to develop their applications. Call it GoogleAlibaba Group, and Grab. You can see a list of applications built using Flutter on the Flutter Showcase page.

Are you one of them? Well, before trying, it’s a good idea to first learn the meaning, advantages, and disadvantages of the Flutter framework in this article. Come on, let’s start the discussion!


What is Flutter?


Flutter is Google’s Mobile UI Framework for creating high-quality native interfaces on iOS and Android in no time. Flutter works with existing code, is used by developers and organizations around the world, is free and open source.

So, it is a platform used by developers to create multiplatform applications with only one coding base (codebase). This means that the resulting application can be used on various platforms, both Android mobile, iOS, web, and desktop.

Flutter has two important components, namely, the Software Development Kit (SDK) and also the User Interface Framework.

The Software Development Kit (SDK) is a collection of tools that function to create applications that can run on various platforms.

UI frameworks are UI components, such as text, buttons, navigation, and more, that you can customize as needed.

Before it was officially launched in December 2018, Flutter had actually been developed by Google since 2015. Then, in 2019, Flutter’s popularity began to skyrocket and many developers flocked to use Flutter.

Fluter’s skyrocketing factor is none other than the convenience it offers. There are many Flutter applications that have appeared on the Google Play Store and App Store, For example HamiltonAlibabaGoogle Ads, and many more.

How Does the Flutter Framework Work?

How Flutter works is actually quite simple. Here’s how Flutter works on Android and iOS platforms:

  1. Developers develop applications with Dart code and widgets provided in the Flutter framework.
  2. If on Android, the code written will be compiled with the C++ engine using the Android NDK (Native Development Kit). If on iOS, the code will be compiled with the machine compiled with LLVM (Low-Level Virtual Machine).
  3. For Android, native code will be compiled again with Dart Compiler.
  4. After the code is adapted to each device, the application can be run on various platforms.

The Advantages of the Flutter Framework and Why Should You Use It?

Still hesitant to use Flutter? Take a look at the following advantages of Flutter!

1. Easier and Faster Application Development

The first reason you should try the Flutter framework is that it provides features that help make the development process easier and faster.

Flutter provides user interface widgets developed by Google with high coding quality. You can customize these widgets easily, without the need to write coding from scratch.

Not only that, Flutter also has a Hot Reload feature that will display coding results in a flash. So, you can experiment with adding features and fixing bugs faster.

Besides, you don’t need to master another language to build apps on different platforms. Just take advantage of the widgets provided by Flutter, you can build apps for Android and iOS at once.

2. Attractive Custom User Interface

In addition to making it easier for developers to load applications, Flutter also offers an attractive application user interface.

You can take advantage of a collection of widgets to display applications, such as layouts, navigation, animations, theme styles, fonts, to scrolling display settings.

Interestingly, you can customize the widget according to your needs. So, you can easily create a unique app appearance.


Here’s an example of the Reflectly app design that won the most innovative app design award. This application has smooth transitions, interesting animations and images, to the right color tone.

As you might have guessed, the app uses the Flutter framework to build it.

3. Performance like Native Apps

Although the Flutter application is multiplatform, the performance of the resulting application is no less than that of a native application.

Not only does the design look attractive, the performance for transitions, scrolling, data loading is still optimal on all platforms.

In addition to providing applications with optimal performance, Flutter is also loyal to share tips and tricks so that developers can create lightweight applications.

The best way to improve app performance is by testing and viewing the performance metrics page. Be it speed, memory, app size, and power metrics.

Flutter has also provided the tools, for example, Performance Overlay, Widget Rebuild Tracker, DevTools Memory, and so on.

With maintained performance, the user experience of application users can also improve.

4. Development Costs More Efficient

As is known, Flutter is a multiplatform application development framework. That means, the development process can be more efficient. So, you don’t need to make the application twice for different platforms.

Coupled with the Hot Reload feature, UI widgets, data backend, platform integration, accessibility and internationalization, packages and plugins that make it easy for developers to create applications. So, they can save more effort, time and cost.

This is one of the reasons why many developers have invaded the Flutter framework. This advantage is certainly difficult for you to get if you use other frameworks that do not yet provide these features.

Disadvantages of Flutter Framework

Since the Flutter platform is a relatively new framework, there are some drawbacks that you also need to be aware of to anticipate. Here’s the review!

1. Few Third-Party Libraries

Flutter is a new technology that is on the rise. Because of its new existence, the developer community is still growing. As a result, the resource code or library that is owned is also still small.

This library is a collection of coding functions that you can reuse to make building applications easier. Unfortunately, you may not find many libraries for developing apps in Flutter. So you have to be more creative and do a lot of testing.

2. Generated Applications Are Large

The performance of applications developed by Flutter is quite stable. However, these applications tend to be “heavy” or have large file sizes.

In comparison, the size of a simple app is “Hello World!” in native applications only about 500 KB. Meanwhile, in Flutter it can reach 4.7 MB.

This of course will take up a lot of user device storage space, right? If, the user’s storage space is limited, the performance of the app may be affected. In fact, users may even discourage their intention to download the application.

3. Need to Learn New Programming Language

To use Flutter, you need to learn a new programming language, namely Dart. Dart language is also not very popular and even though it is starting to be widely used by developers.

However, if you already know the Java or C# programming languages, you shouldn’t have too much trouble learning Dart. Also, Flutter has also made video tutorials on its YouTube channel, to make it easier for you to learn Flutter.
