unmap method

K? unmap(K keyMapped)

Implementation

K? unmap(K keyMapped) {
  var key = _keysUnmapping[keyMapped];
  if (key != null) return key;

  var keysNorm = normalizedKeys(keyMapped);

  for (var e in _keysMapping.entries) {
    var k = e.value;
    if (k == keyMapped || keysNorm.contains(k)) {
      return e.key;
    }
  }

  return key;
}
