maybeWhen<TResult extends Object?> method

  1. @optionalTypeArgs
TResult maybeWhen<TResult extends Object?>(
  1. TResult $default(
    1. String $type,
    2. String? background,
    3. String? foreground,
    4. String? accent,
    5. String? accentForeground,
    6. 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? background,  String? foreground,  String? accent,  String? accentForeground,  Map<String, dynamic>? $unknown)?  $default,{required TResult orElse(),}) {final _that = this;
switch (_that) {
case _EmbedExternalViewArticlePublicationTheme() when $default != null:
return $default(_that.$type,_that.background,_that.foreground,_that.accent,_that.accentForeground,_that.$unknown);case _:
  return orElse();

}
