when<TResult extends Object?> method

  1. @optionalTypeArgs
TResult when<TResult extends Object?>(
  1. TResult $default(
    1. String origin,
    2. Validation validation,
    3. String verifyUrl,
    4. bool? isScam,
    )
)

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( String origin,  Validation validation,  String verifyUrl,  bool? isScam)  $default,) {final _that = this;
switch (_that) {
case _VerifyContext():
return $default(_that.origin,_that.validation,_that.verifyUrl,_that.isScam);}
}
