maybeWhen<TResult extends Object?> method

  1. @optionalTypeArgs
TResult maybeWhen<TResult extends Object?>(
  1. TResult $default(
    1. String merchantName,
    2. String countryCode,
    3. bool testEnv,
    4. BillingAddressConfig? billingAddressConfig,
    5. bool isEmailRequired,
    6. bool existingPaymentMethodRequired,
    7. String? label,
    8. double? amount,
    )?, {
  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( String merchantName,  String countryCode,  bool testEnv,  BillingAddressConfig? billingAddressConfig,  bool isEmailRequired,  bool existingPaymentMethodRequired,  String? label,  double? amount)?  $default,{required TResult orElse(),}) {final _that = this;
switch (_that) {
case _GooglePayInitParams() when $default != null:
return $default(_that.merchantName,_that.countryCode,_that.testEnv,_that.billingAddressConfig,_that.isEmailRequired,_that.existingPaymentMethodRequired,_that.label,_that.amount);case _:
  return orElse();

}
