maybeMap<TResult extends Object?> method

  1. @optionalTypeArgs
TResult maybeMap<TResult extends Object?>({
  1. TResult googlePay(
    1. PlatformPayConfirmParamsGooglePay value
    )?,
  2. TResult applePay(
    1. PlatformPayConfirmParamsApplePay value
    )?,
  3. TResult web(
    1. PlatformPayConfirmParamsWeb value
    )?,
  4. required TResult orElse(),
})

A variant of map that fallback to returning orElse.

It is equivalent to doing:

switch (sealedClass) {
  case final Subclass value:
    return ...;
  case _:
    return orElse();
}

Implementation

@optionalTypeArgs TResult maybeMap<TResult extends Object?>({TResult Function( PlatformPayConfirmParamsGooglePay value)?  googlePay,TResult Function( PlatformPayConfirmParamsApplePay value)?  applePay,TResult Function( PlatformPayConfirmParamsWeb value)?  web,required TResult orElse(),}){
final _that = this;
switch (_that) {
case PlatformPayConfirmParamsGooglePay() when googlePay != null:
return googlePay(_that);case PlatformPayConfirmParamsApplePay() when applePay != null:
return applePay(_that);case PlatformPayConfirmParamsWeb() when web != null:
return web(_that);case _:
  return orElse();

}
