whenOrNull<TResult extends Object?> method

@optionalTypeArgs TResult? whenOrNull<TResult extends Object?>(TResult? $default(String id, String name, String homepage, @JsonKey.new(name: 'image_id') String imageId, int order, @JsonKey.new(name: 'android_app_id') String? androidAppId, @JsonKey.new(name: 'mobile_link') String? mobileLink, @JsonKey.new(name: 'desktop_link') String? desktopLink, @JsonKey.new(name: 'link_mode') String? linkMode, @JsonKey.new(name: 'webapp_link') String? webappLink, @JsonKey.new(name: 'app_store') String? appStore, @JsonKey.new(name: 'play_store') String? playStore, String? rdns, @JsonKey.new(name: 'chrome_store') String? chromeStore, List<Injected>? injected, List<String>? chains, List<String>? categories, String? description, @JsonKey.new(name: 'badge_type') String? badgeType, @JsonKey.new(name: 'supports_wc') bool? supportsWc, @JsonKey.new(name: 'is_top_wallet') bool? isTopWallet,)?)

A variant of when that fallback to returning null

It is equivalent to doing:

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

Implementation

@optionalTypeArgs TResult? whenOrNull<TResult extends Object?>(TResult? Function( String id,  String name,  String homepage, @JsonKey(name: 'image_id')  String imageId,  int order, @JsonKey(name: 'android_app_id')  String? androidAppId, @JsonKey(name: 'mobile_link')  String? mobileLink, @JsonKey(name: 'desktop_link')  String? desktopLink, @JsonKey(name: 'link_mode')  String? linkMode, @JsonKey(name: 'webapp_link')  String? webappLink, @JsonKey(name: 'app_store')  String? appStore, @JsonKey(name: 'play_store')  String? playStore,  String? rdns, @JsonKey(name: 'chrome_store')  String? chromeStore,  List<Injected>? injected,  List<String>? chains,  List<String>? categories,  String? description, @JsonKey(name: 'badge_type')  String? badgeType, @JsonKey(name: 'supports_wc')  bool? supportsWc, @JsonKey(name: 'is_top_wallet')  bool? isTopWallet)?  $default,) {final _that = this;
switch (_that) {
case _AppKitModalWalletListing() when $default != null:
