when<TResult extends Object?> method

  1. @optionalTypeArgs
TResult when<TResult extends Object?>(
  1. TResult $default(
    1. List<String> assetNamespaces,
    2. dynamic capabilities,
    3. List<String> events,
    4. List<String> methods,
    5. String name,
    )
)

A switch-like method, using callbacks.

As opposed to map, this offers destructuring. It is equivalent to doing:

switch (sealedClass) {
  case Subclass(:final field):
    return ...;
  case Subclass2(:final field2):
    return ...;
}

Implementation

@optionalTypeArgs TResult when<TResult extends Object?>(TResult Function( List<String> assetNamespaces,  dynamic capabilities,  List<String> events,  List<String> methods,  String name)  $default,) {final _that = this;
switch (_that) {
case _SupportedNamespace():
return $default(_that.assetNamespaces,_that.capabilities,_that.events,_that.methods,_that.name);}
}
