when<TResult extends Object?> method

  1. @optionalTypeArgs
TResult when<TResult extends Object?>(
  1. TResult $default(
    1. String $type,
    2. List<UPostInteractionSettingsPrefThreadgateAllowRules>? threadgateAllowRules,
    3. List<UPostInteractionSettingsPrefPostgateEmbeddingRules>? postgateEmbeddingRules,
    4. Map<String, dynamic>? $unknown,
    )
)

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( String $type, @UPostInteractionSettingsPrefThreadgateAllowRulesConverter()  List<UPostInteractionSettingsPrefThreadgateAllowRules>? threadgateAllowRules, @UPostInteractionSettingsPrefPostgateEmbeddingRulesConverter()  List<UPostInteractionSettingsPrefPostgateEmbeddingRules>? postgateEmbeddingRules,  Map<String, dynamic>? $unknown)  $default,) {final _that = this;
switch (_that) {
case _PostInteractionSettingsPref():
return $default(_that.$type,_that.threadgateAllowRules,_that.postgateEmbeddingRules,_that.$unknown);case _:
  throw StateError('Unexpected subclass');

}
