A simple implementation of bKash payment gateway in flutter with tokenized checkout feature.

## Features

* A Simple App with a button to `Checkout`

* Pressing the button initiates bKash payment dialogs

* Returns a success message with tranId if payment is successful

## Usage

Official link for API documentation and demo checkout

* [bKash API Specifications](https://developer.bka.sh/v1.2.0-beta/reference)

* [bKash Checkout Demo](https://merchantdemo.sandbox.bka.sh)

### Production

Replace the credentials for production uses in `bkash_credentials.dart` with your own bKash credentials and change the parameter `isSandbox: false`.

```dart

  static const String username = 'app_username';

  static const String password = 'app_password';

  static const String appKey = 'app_key';

  static const String appSecret = 'app_secret';

```

### Pay With bKash

Basically this the implementation of payment without an agreement. Use the `makePayment` method to pay

#### Request

```dart

final result = await bkashApi.makePayment(

    context: context,

    amount: 50.0,

    payerReference: "01770618575",

    merchantInvoiceNumber: "INV-123",

    isSandbox: false,

  );

```

#### Response

```json

{

  "amount": "50.0",

  "trxId": "BJJ90KGFBH",

  "paymentId": "TR0011HjY1p6A1729311405472",

  "payerReference": "01770618575",

  "customerMsisdn": "01770618575",

  "merchantInvoiceNumber": "INV-123",

  "paymentExecuteTime": "2024-10-19T10:17:14:333"

}

```

## Error Handling

In case of any error it's throw `PaymentException`. You can handle the exception using a try-catch block.

```dart

try {

  // Make a payment

} on PaymentException catch (e) {

  // Handle the error

  log(e.message);

}

```
