title: The dart implementation behind String.hashCode for use in other language
body: <p>I mistakenly depended on String.hashCode's value in a flutter app and stored it in a server side. Now I want to be able to calculate a hash code of a string in nodeJS and get the same result as dart...</p>
  
  <p>How can I achieve it? Didn't find the actual implementation of the String.hashCode in dart.</p>
