make field declarations optional

>>> user feedback <<<

Why do we have to declare variables used in a class??
I mean, look at that

  "num x;" ...

this syntax is really aweful..

class Test2 {
 num x;
 Test2(x) {
   this.x = x;
 }

I my opinion, variables defined in constructor are enough.
this syntax definitely decreases productivity making code verbose.

Second, well... I really really hope that you guys get rid of {} syntax..
Why don't you just use something similar to Python Syntax??

   Class Test:
      Test(x = 3):
           this.x = x

Compare it to

   class Test{
     num x;
     Test(x){
       this.x = x;
     }
   }

even this simple class looks verbose using 2 times of lines.

I guess it's very complicated to change these syntaxes but..

Dart needs something more fresh than old-fashioned style code.

I really really hope Dart go toward mordern style not old style.

Thanks..

Personally, I really really love you guys.. you're making my dream come true!! but somewhat differently..

It's always useful to get feedback. On the other hand, comments like "this syntax is really awful" contain no information. There is no way to please everyone's syntactic preferences. And of course, the user seems unaware that one can write

class Test{
  num x;
  Test(this.x);
}
