The dart implementation behind String.hashCode for use in other language

Question

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...

How can I achieve it? Didn't find the actual implementation of the String.hashCode in dart.

Answer 1

The vm implementation of String.hashCode can be found in the sdk repo on github (https://github.com/dart-lang/sdk):

Example:

• StringHasher in runtime/vm/object.cc
• CombineHashes/FinalizeHash in runtime/vm/hash.h
