A1: The GMPay Flutter Plugin is a Flutter package that allows developers to integrate the GMPay payment platform into their Flutter applications. It provides a seamless way to facilitate secure and convenient payment transactions for businesses and individuals.
A2: To obtain API keys for GMPay, follow these steps:
-
Sign up for a GMPay account on the GMPay app.
-
Once logged in, navigate to services then press on the merchant icon.
-
You'll find an option to create API keys. Click on it and follow the instructions to generate your public and secret keys.
-
Make sure to keep your secret key secure and never expose it in client-side code or public repositories, as it is a sensitive credential.
A3: To install the GMPay Flutter Plugin, follow these steps:
-
Open your Flutter project.
-
Add the following dependency to your
pubspec.yaml
file:dependencies: gmpay: ^1.0.0
-
Run
flutter pub get
to install the package. -
You're now ready to use the GMPay Flutter Plugin in your project.
A4: You should configure the GMPay Flutter Plugin with your API keys before using it. Here's how:
import 'package:gmpay_flutter/gmpay_flutter.dart';
void configureGMPay() {
GMPayFlutter.configure(
apiKey: 'your_api_key',
secret: 'your_secret_key',
);
}
Replace 'your_api_key'
and 'your_secret_key'
with your actual GMPay API keys.
A5: To initiate a payment transaction, you can use the initiatePayment
method. Here's an example:
import 'package:gmpay_flutter/gmpay_flutter.dart';
void initiatePayment() {
GMPayFlutter.initiatePayment(
amount: 100.00, // Replace with the actual payment amount
description: 'Payment for Product X',
// Add other payment parameters as needed
);
}
Replace the amount
and description
with the specific details of your payment.
A6: You can handle the result of a payment transaction by providing a callback function when calling the payment method. The callback function will be invoked with the transaction details or a null value if the transaction was canceled or failed.
Example:
GMPayFlutter.initiatePayment(
// ...
callback: (transactionResult) {
if (transactionResult == null) {
print("Transaction canceled");
} else {
print(transactionResult);
}
},
);
A7: If your payment transactions are failing, consider the following:
-
Ensure that you've configured the GMPay Flutter Plugin with the correct API keys using the
configure
method. -
Check your internet connection, as a stable internet connection is required to communicate with GMPay's servers.
-
Verify that the payment details, such as the amount and account, are correctly specified in your payment requests.
-
If you receive error messages, consult the GMPay documentation or contact GMPay support for specific error resolution.
