Flutter : One Codebase to 6 Platforms

This time, I would like to introduce a framework that beginners in programming or junior‑level developers should learn. That is the Flutter framework, an all‑in‑one platform framework created by Google. Flutter was first introduced by Google in 2015. Its main language is Dart , which was also developed by Google. Dart is a high‑level language similar to C# and Java, making it easy to learn. And since it is developed by a tech giant like Google, you can trust its community support and long‑term development.

Therefore, Flutter is a framework that juniors and first‑time learners should definitely choose. Its main advantage is the “one codebase for all platforms” approach with a single codebase, you can run apps on web, Android, iOS, and desktop. Other frameworks don’t provide this level of cross‑platform support. For example, Laravel is limited to web only, while frameworks like React or Node are mainly for Android and web. Flutter, however, covers them all.

Another advantage is faster development time. Thanks to the hot reload system, you can instantly test UI changes as soon as you edit the code. Flutter also provides a wide variety of widgets and UI components, created by Google and the developer community, which are easy to use. On top of that, in today’s job market, the demand for Flutter developers is very high.

For these reasons, Flutter is a framework worth choosing. This blog explains Flutter and highlights its advantages.

What Is Flutter?

Flutter is a UI toolkit that allows developers to build apps for Android, iOS, Web, and Desktop all from a single codebase. This is Flutter’s unique capability. No other framework so far has been able to create true cross‑platform apps with just one codebase like Flutter.

Flutter is built with the Dart programming language, which was created by Google. Dart is similar to Java and C++, but since it is a high‑level programming language, it is relatively easy to learn.

Flutter was first introduced by Google in 2017, and Flutter 1.0 was officially released in December 2018.
