Pattern: Unnecessary constructor name

Issue: -

Description

PREFER using the default unnamed Constructor over .new.

Given a class C, the named unnamed constructor C.new refers to the same constructor as the unnamed C. As such it adds nothing but visual noise to invocations and should be avoided (unless being used to identify a constructor tear-off).

Example of incorrect code:

class A {
  A.new(); // LINT
}

var a = A.new(); // LINT

Example of correct code:

class A {
  A.ok();
}

var a = A();
var aa = A.ok();
var makeA = A.new;
