ArgumentError constructor

ArgumentError(
  1. [dynamic message]
)

Creates an error with message describing the problem with an argument.

Existing code may be using message to hold the invalid value. If the message is not a String, it is assumed to be a value instead of a message.

Implementation

@pragma("vm:entry-point")
ArgumentError([this.message])
    : invalidValue = null,
      _hasValue = false,
      name = null;
