Usage: #
Import package,
import ‘package: aggrepay_flutter/aggrpay_flutter.dart’
Create hash for payment
Create a method for Generating hash.
Write a variable with Map<String, dynamic> type to create a hash.
Then create a List with String type and add all key names as string.
Sort that list with inbuilt sort(); method.
Create a For Loop for adding a vertical pipeline for each data.
Add Crypto package for creating hash.
Then create a hash with SHA512 algorithm.
Convert the hash to uppercase with .toUpperCase(); inbuilt method.
Example :
void createHash(String amount, String order) {
var params = {
'api_key': api_key,
'order_id': orderController.text,
'mode': mode,
'description': description,
'currency': currency,
'amount': amountController.text,
'name': name,
'email': email,
'phone': phone,
'city': city,
'state': state,
'country': country,
'zip_code': zip_code,
'address_line_1': address_line_1,
'return_url': return_url
};


List _hashList = [
"address_line_1",
"amount",
"api_key",
"city",
"country",
"currency",
"description",
"email",
"mode",
"name",
"zip_code",
"order_id",
"phone",
"return_url",
"state",
];

_hashList.sort();

var hashData = 'your salt key';
for (int i = 0; i < _hashList.length; i++) {
if (params.keys.contains(_hashList[i])) {
if (params[_hashList[i]].toString().isNotEmpty) {
hashData += '|' + params[_hashList[i]]!.trim().toString();
}
}
}

var hashed = sha512.convert(utf8.encode(hashData.toString()));
setState(() {
hash = hashed.toString().toUpperCase();
});
}

Create method for Aggrepay #
Create an async method for communicating with aggrepay sdk which will return a payment response.
Then create an instance for Aggrepay with the static method “pay” which accepts map type payment details.
Example,
Map<String, String> params = {
'api_key': api_key,
'hash': hash,
'order_id': order_id,
'mode': mode.toUpperCase(),
'description': description,
'currency': currency,
'amount': amount,
'name': name,
'email': email,
'phone': phone,
'city': city,
'state': state,
'country': country,
'zip_code': zip_code,
'address_line_1': address_line_1,
'return_url': return_url
};


void open(Map<String, dynamic> params) async {
try {
var response = await AggrepayFlutter.pay(params);
log(response.toString());
PaymentResponse data = PaymentResponse.fromJson(response);
if (data.status.toString().contains('success')) {
Navigator.of(context).push(
MaterialPageRoute(
builder: (_) => PaymentSuccess(paymentResponse: data),
),
);
} else {
ScaffoldMessenger.of(context).showSnackBar(
const SnackBar(
content: Text('Transaction failed!'),
backgroundColor: Colors.black,
),
);
}
} on PlatformException {
address_line_1;
}
}

In the above example response variable returns a payment response as Json object with respective message and payment_response.
