Future<ChargeResponse> validatePayment(String otp, String flwRef, Client client, bool isDebugMode, String publicKey, dynamic isBankAccount, [ String feature = "", ])

Validates payments with OTP returns an instance of ChargeResponse or throws an error

Implementation

static Future<ChargeResponse> validatePayment(
    String otp,
    String flwRef,
    http.Client client,
    final bool isDebugMode,
    final String publicKey,
    final isBankAccount,
    [String feature = ""]) async {
  final stopWatch = Stopwatch();

  final url = FlutterwaveURLS.getBaseUrl(isDebugMode) +
      FlutterwaveURLS.VALIDATE_CHARGE;
  final uri = Uri.parse(url);
  final ValidateChargeRequest chargeRequest =
      ValidateChargeRequest(otp, flwRef, isBankAccount);
  final payload = chargeRequest.toJson();
  try {
    final http.Response response = await client.post(uri,
        headers: {HttpHeaders.authorizationHeader: publicKey}, body: payload);

    if (feature.isNotEmpty) {
      MetricManager.logMetric(
          client, publicKey, feature, "${stopWatch.elapsedMilliseconds}ms");
    }
    final ChargeResponse cardResponse =
        ChargeResponse.fromJson(jsonDecode(response.body));
    return cardResponse;
  } catch (error) {
    if (feature.isNotEmpty) {
      MetricManager.logMetric(client, publicKey, "{$feature}_ERROR",
          "${stopWatch.elapsedMilliseconds}ms");
    }
    throw (FlutterWaveError(error.toString()));
  }
