maybeWhen<TResult extends Object?> method

TResult maybeWhen<TResult extends Object?>(
  1. TResult $default(
    1. String $type,
    2. String code,
    3. String name,
    4. @ProfileViewBasicConverter() ProfileViewBasic owner,

    12. Map<String, dynamic>? $unknown,
    )?, {
  2. required TResult orElse(),
})

A variant of when that fallback to an orElse callback.

It is equivalent to doing:

switch (sealedClass) {
  case Subclass(:final field):
    return ...;
  case _:
    return orElse();
}

Implementation

@optionalTypeArgs TResult maybeWhen<TResult extends Object?>(TResult Function( String $type,  String code,  String name, @ProfileViewBasicConverter()  ProfileViewBasic owner,  int memberCount,  int memberLimit,  bool requireApproval, @JoinRuleConverter()  JoinRule joinRule, @LinkEnabledStatusConverter()  LinkEnabledStatus enabledStatus, @ConvoViewConverter()  ConvoView? convo, @JoinLinkViewerStateConverter()  JoinLinkViewerState? viewer,  Map<String, dynamic>? $unknown)?  $default,{required TResult orElse(),}) {final _that = this;
switch (_that) {
case _JoinLinkPreviewView() when $default != null:
return $default(_that.$type,_that.code,_that.name,_that.owner,_that.memberCount,_that.memberLimit,_that.requireApproval,_that.joinRule,_that.enabledStatus,_that.convo,_that.viewer,_that.$unknown);case _:
  return orElse();
