I want new List() to have a parameter 'growable'.

[Suguru Inatomi]

When I want a growable list whose length is 10,

Now

var list = new List()..length = 10;
or
var list = []..length = 10;

But I want to define the length in the constructor.

var list = new List(10, growable: true);

thanks.

Would `new List.from(new List(10))` work for you?

Alternatively:

new List.generate(10, (_) => null, growable: true);

Would this work?

final list = new List()..length = 10;

I think Dart is like Java. In Java, "new ArrayList(10)" gives a growable list.
List of Dart is defined the single abstract class "List". I cannot detect that list is growable in my editor. So, I want to define fixed-length list explicitly.
