when<TResult extends Object?> method

  1. @optionalTypeArgs
TResult when<TResult extends Object?>(
  1. TResult $default(
    1. UserInterfaceStyle? userInterfaceStyle,
    2. @JsonKey.new(includeFromJson: false, includeToJson: false) FinancialConnectionsEventHandler? onEvent
    )
)

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( UserInterfaceStyle? userInterfaceStyle, @JsonKey(includeFromJson: false, includeToJson: false)  FinancialConnectionsEventHandler? onEvent)  $default,) {final _that = this;
switch (_that) {
case _CollectBankAccountTokenParams():
return $default(_that.userInterfaceStyle,_that.onEvent);case _:
  throw StateError('Unexpected subclass');

}
}
