latestEpochParameters method

@override Future<Result<LinearFee, String>> latestEpochParameters({ int epochNumber = 0, })

Return the fee parameters for the given epoch number or the latest epoch if no number supplied.

Implementation

@override
Future<Result<LinearFee, String>> latestEpochParameters(
    {int epochNumber = 0}) async {
  if (epochNumber == 0) {

    if (blockResult.isErr()) return Err(blockResult.unwrapErr());
    epochNumber = blockResult.unwrap().epoch;
  }
  final paramResult = await dioCall<EpochParamContent>(
    request: () => blockfrost

        .epochsNumberParametersGet(number: epochNumber),
    onSuccess: (data) => logger.i(
        "blockfrost.getCardanoEpochsApi().epochsNumberParametersGet(number:$epochNumber) -> ${serializers.toJson(EpochParamContent.serializer, data)}"),
