Usage

Initializing a Zainpay instance

To create an instance, you should call the Zainpay constructor. This constructor accepts a mandatory instance of the following:

• context
• publicKey
• isTest

It returns an instance of Zainpay which we then call the async methods on for every feature requested.

    final Zainpay zainpay = Zainpay(
        context: context,
        publicKey: getPublicKey(),
        isTest: true
    );

Handling the response

Calling the createZainbox(name, tags, callbackUrl, email) method returns a Future of CreateZainboxResponse? which we await for the actual response as seen above.

final CreateZainboxResponse? response = await zainpay.createZainbox(name, tags, callbackUrl, email);

if (response != null) {
    showLoading(response.status!);
    debugPrint("${response.toJson()}");
} else {
    showLoading("No Response!");
