Is Flutter better than HTML?

Flutter actually controls every pixel that is drawn to the screen and doesn’t use HTML , JavaScript, or CSS to define any of its look or logic.

Flutter is, underneath it all, a library of Dart classes. There is no markup language involved or JSX-style hybrid language. Every bit of front-end code is written in Dart. No HTML .

Always learn HTML first . JavaScript can be learnt as a basics of Programming languages. For example, if your main aim is learning Java, you can start with JavaScript as JavaScript is forgiving and gives you less headache with your language syntax.
