Opening payment form

To open the payment form:

1. Create the EcmpPaymentInfo object.

This object must contain the following required parameters:

• projectId (int) — a project identifier assigned by Flashpay
• paymentId (String) — a payment identifier unique within the project
• paymentCurrency (String) — the payment currency code in the ISO 4217 alpha-3 format
• paymentAmount (int) — the payment amount in the smallest currency units
• customerId (String) — a customer's identifier within the project
• signature (String) — a request signature generated after all required parameters have been specified

final paymentInfo = EcmpPaymentInfo(
            projectId: 12312,
            paymentId: "paymentId",
            paymentAmount: 100,
            paymentCurrency: "USD",
          );

2. Sign the parameters contained in the EcmpPaymentInfo object.

final paramsForSignature = await ecmpPlugin.getParamsForSignature(paymentInfo);
paymentInfo.signature = "CALCULATED_SIGNATURE_FROM_YOUR_BACKEND";

3. Create the EcmpPaymentOptions object that contains the required parameter actionType (enum) with the value specifying the required operation type:

• EcmpActionType.sale
• EcmpActionType.auth
• EcmpActionType.verify
• EcmpActionType.tokenize In addition to the required EcmpPaymentInfo object and the actionType parameter, the following example contains several additional parameters including the EcmpAdditionalFields object with data specified in the fields that are used for collecting customer information.

 final paymentOptions = EcmpPaymentOptions(
    actionType: EcmpActionType.Sale,
    paymentInfo: paymentInfo,
    isDarkTheme: false,
    //if need use real service- set EcmpMockModeType.disabled
    mockModeType: EcmpMockModeType.success,
    //set display mode if need
    screenDisplayModes: [
      EcmpScreenDisplayMode.hideDeclineFinalScreen
    ],
    //set additional fields if need
    additionalFields: [
      EcmpAdditionalField(type: "email", value: "mail@mail.com"),
      EcmpAdditionalField(type: "first_name", value: "firstName"),
    ],
    //set recipient info if need
    recipientInfo: EcmpRecipientInfo(),
    //set recurrent info if need
    recurrentData: EcmpRecurrentData(),
);

4. Create the EcmpPlugin object.

final ecmpPlugin = EcmpPlugin();

6. Open the payment form and handle result.

final response = await ecmpPlugin.sdkRun(paymentOptions);
