EnumIndex<E> class

Indexes a list of enum values by simple name.

In Dart enum names are prefixed with enum class name. For example, for enum Vote { yea, nay }, Vote.yea.toString() produces "Vote.yea" rather than just "yea" - the simple name. This class provides methods for getting and looking up by simple names.

Example:

enum Vote { yea, nay }
final index = EnumIndex(Vote.values);
index.lookupBySimpleName('yea'); // returns Vote.yea
index.toSimpleName(Vote.nay); // returns 'nay'
