map constant
A tree-shakable combined map of codeMap and codeShortMap, providing a unified view of language codes and their NaturalLanguage objects, for a O(1) access time.
Example usage:
NaturalLanguage.map[' en ']; // LangEng().
Implementation
static const map = UpperCaseIsoMap(
{...naturalLanguageCodeMap, ...naturalLanguageCodeOtherMap},
exactLength: null, // ignore: avoid-passing-default-values, is not default.
);
