assert_in_redirecting_constructor

A redirecting constructor can't have an 'assert' initializer.

The analyzer produces this diagnostic when a redirecting constructor (a constructor that redirects to another constructor in the same class) has an assert in the initializer list.

The following code produces this diagnostic because the unnamed constructor is a redirecting constructor and also has an assert in the initializer list:

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

If the assert isn't needed, then remove it:

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

If the assert is needed, then convert the constructor into a factory constructor:

class C {
  factory C(int x) {
    assert(x > 0);
    return C.name();
  }
  C.name() {}
}
