maybeWhen<TResult extends Object?> method

  1. @optionalTypeArgs
TResult maybeWhen<TResult extends Object?>(
  1. TResult $default(
    1. @JsonKey.new(includeIfNull: false) String? name,
    2. @JsonKey.new(includeIfNull: false) String? url,
    3. @JsonKey.new(includeIfNull: false) String? email
    )?, {
  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(@JsonKey(includeIfNull: false)  String? name, @JsonKey(includeIfNull: false)  String? url, @JsonKey(includeIfNull: false)  String? email)?  $default,{required TResult orElse(),}) {final _that = this;
switch (_that) {
case _Contact() when $default != null:
return $default(_that.name,_that.url,_that.email);case _:
  return orElse();

}
}
