memberGet method

@override dynamic memberGet(String id, { String? from, bool isRecursive = false, bool ignoreUndefined = true, })

Get the value of a static member from this HTClass via memberGet operator '.' for symbol searching, use the same name method on HTClassNamespace instead.

Implementation

@override
dynamic memberGet(String id,
    {String? from, bool isRecursive = false, bool ignoreUndefined = true}) {
  final getter = '${InternalIdentifier.getter}$id';
  final constructor = this.id != id
      ? '${InternalIdentifier.namedConstructorPrefix}$id'
      : InternalIdentifier.defaultConstructor;

  // if (isExternal && !internal) {
  //   final value =
  //       externalClass!.memberGet(id != id ? '$id.$id' : id);
  //   return value;
  // } else {
  if (namespace.symbols.containsKey(id)) {
    final decl = namespace.symbols[id];
    if (decl == null) return null;
    if (decl is HTDeclaration) {
      if (decl.isPrivate &&
          from != null &&
          !from.startsWith(namespace.fullName)) {
