The webdev serve command uses dartdevc by default, but you can switch to dart2js using the –release flag.

Does Flutter compile to JavaScript?

Why Dart is not popular?

I wouldn’t say Dart is a failure at all. That being said, the Dart project has long abandoned the goal of replacing JavaScript in the browser, and instead provides a VM, Flutter, and a to-JS compiler. Many people do not know this, and have written the language off entirely.

What is the difference between DART and JavaScript?

Unlike vanilla JavaScript, Dart supports null safety, making any type non-nullable by default (as of Dart 2.12). One key benefit of this is that null reference exceptions are caught when writing code, so they are unlikely to occur at runtime.

Is dart2js a compiler or not?

A “transpiler” is just another name for a compiler which is typically only used for compiling into another user-writable language (e.g., from Dart to JavaScript) instead of to a low-level machine language (assemebler, byte code, machine code). Still, transpilers are compilers, so calling dart2js a compiler is correct. Show activity on this post.
