RangeError.value constructor Null safety

RangeError.value(
  1. num value,
  2. [String? name,
  3. String? message]

An optional name can specify the argument name that has the invalid value, and the message can override the default error description.

RangeError.value(num value, [String? name, String? message])
    : start = null,
      end = null,
      super.value(value, name, message ?? "Value not in range");
