Creates error containing the invalid value
.
A message is built by suffixing the message
argument with the name
argument (if provided) and the value. Example
"Invalid argument (foo): null"
The name
should match the argument name of the function, but if the function is a method implementing an interface, and its argument names differ from the interface, it might be more useful to use the interface method's argument name (or just rename arguments to match).
@pragma("vm:entry-point") ArgumentError.value(value, [this.name, this.message]) : invalidValue = value, _hasValue = true;
