What if I tell you that Flutter is just a library of programming language called Dart? Yes it is true. Writing an app in Flutter is writing Dart. Flutter is, underneath it all, a library of Dart classes.

So, What is Dart & What are the benefits ?

Dart is just another programming language developed by Google, and yes, Flutter too. But let me explain you why Dart is more special compared to other programming languages like Javascript we use to develop cross platform mobile apps.

As all of us know, programming languages can be, as it turns out, hard to learn. The fundamentals of Dart are similar to all higher-level languages. But the benefit is, You’ll find familiarity in Dart syntax and design if you’re coming from JavaScript, Java, Python, Ruby or any other C-like language. For me, it didn’t took more than one hour to get familiar with all Dart basics as i’m already well familiar with JavaScript development.

It’s not clear why Dart is developed by Google. But for whatever the reason, What Google came up with works well for writing modern UIs. Let me point out few points about Dart;

  • Dart supports both just-in-time (JIT) compiling and ahead-of-time (AOT) compiling. Means, you will be able to test your UI without compiling your code. This makes Flutter fast (a win for the user and the developer)
  • Dart is object-oriented. This makes it easy to write visual user experiences with Dart, with no need for a markup language or JSX-style hybrid language. 
  • The type system and object orientation make it easy to reason about writing reusable components for the UI. 
  • Dart also comes with few functional programming features that make it easier to turn your data into pieces of UI.
  • Reactive programming support with asynchronous, stream-based programming features. ?

Dart vs JavaScript

If you ever used JavaScript in cross-platform mobile app development, you know how hard to debug those apps and major performance bottleneck. Think about scrolling on your app, it’s not feel smooth. That’s because JavaScript is act like a bridge between your code and native component in run time and compilation is happening in runtime. But, Flutter compiles to actual native code and is rendered using the same engine that Chrome uses to render (called Skia), so there’s no need to translate Dart at runtime. This means apps don’t lose any performance or productivity when running on a user’s device.

Do you really want to be a champion Dart Developer to build Flutter Apps?

Exactly not. Do you have any previous experience in any object oriented programming language? Then you’re already smart enough to be a Flutter developer. Just get familiar with basic Dart syntax and you’re good to go.

Do you know what’s the best way to learn a new language? Start build an app with that language. 🙂
