memberSet method

@override void memberSet(String id, dynamic value, { String? from, bool defineIfAbsent = false, String? cast, bool throws = true, })

Set the value of a member from this HTInstace via memberGet operator '.' for symbol searching, use the same name method on HTInstanceNamespace instead. HTInstance overrided HTObject's memberSet, with a new named parameter cast. If cast is provided, then the instance will only search that cast's corresponed HTInstanceNamespace.

Implementation

@override
void memberSet(
  String id,
  dynamic value, {
  String? from,
  bool defineIfAbsent = false,
  String? cast,
  bool throws = true,
