primary_constructor_cannot_redirect

A primary constructor can't be a redirecting constructor.

The analyzer produces this diagnostic when a primary constructor redirects to another constructor.

The following code produces this diagnostic because the primary constructor has a redirect to the constructor C.named:

class C(int x) {
  C.named() : this(0);
  this : assert(x > 0), this.named();
}

If the redirection isn't necessary, then remove it:

class C(int x) {
  C.named() : this(0);
  this : assert(x > 0);
}

If the redirection is necessary, then convert the primary constructor into a secondary constructor, and rework other constructors as necessary:

class C {
  C.named();
  C(int x) : this.named();
}
