String.fromCharCode constructor Null safety

  1. int charCode

Allocates a new String for the specified charCode.

If the charCode can be represented by a single UTF-16 code unit, the new string contains a single code unit. Otherwise, the length is 2 and the code units form a surrogate pair. See documentation for fromCharCodes.

Creating a String with one half of a surrogate pair is allowed.


external factory String.fromCharCode(int charCode);
