maybeWhen<TResult extends Object?> method

@optionalTypeArgs TResult maybeWhen<TResult extends Object?>(TResult $default(String from, String to, String value, String? gas, String? gasPrice, String? maxFeePerGas, String? maxPriorityFeePerGas, String? input, String? data,)?, { 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 from,  String to,  String value,  String? gas,  String? gasPrice,  String? maxFeePerGas,  String? maxPriorityFeePerGas,  String? input,  String? data)?  $default,{required TResult orElse(),}) {final _that = this;
switch (_that) {
case _EvmTransactionParams() when $default != null:
return $default(_that.from,_that.to,_that.value,_that.gas,_that.gasPrice,_that.maxFeePerGas,_that.maxPriorityFeePerGas,_that.input,_that.data);case _:
  return orElse();

}
}
