final is too long

[mgenware]

Of all the keywords a language introduces, declaring a local final variable could easily be the most frequently used one. final (5 letters) just seems too long compared to other languages (Rust -> let(3), Swfit -> let(3), Kotlin -> val(3)). I usually disable the lint rule prefer_final_locals and go all var in my projects just to type less cuz it's used so frequently, typing 2 less letters can really speed up coding.

One similar language is JavaScript. It uses const (5) for this purpose. JavaScript also has to type function (8) to declare a function. Other languages have much shorter keywoards for that: Rust -> fn(2), Swift -> func(4), Kotlin -> fun(3). You can see the difference here. It would be great if Dart introduces a shorter keyword (like let or val) to replace final.
