when<TResult extends Object?> method

  1. @optionalTypeArgs
TResult when<TResult extends Object?>(
  1. TResult $default(
    1. @JsonKey.new(name: 'origin') String origin,
    2. @JsonKey.new(name: 'id') String id,
    3. @JsonKey.new(name: 'isScam') bool? isScam,
    4. @JsonKey.new(name: 'exp') int expiration,
    5. @JsonKey.new(name: 'isVerified') bool isVerified,
    )
)

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(@JsonKey(name: 'origin')  String origin, @JsonKey(name: 'id')  String id, @JsonKey(name: 'isScam')  bool? isScam, @JsonKey(name: 'exp')  int expiration, @JsonKey(name: 'isVerified')  bool isVerified)  $default,) {final _that = this;
switch (_that) {
case _VerifyClaims():
return $default(_that.origin,_that.id,_that.isScam,_that.expiration,_that.isVerified);}
}
