How to integrate adhaar in my flutter app?

To integrate Aadhaar card verification in your app, we need to establish a partnership with a licensed Authentication Service Agency (ASA) or an e-KYC User Agency (KUA). These entities are authorized by the UIDAI to provide Aadhaar-based authentication services.

Once we connect with the licensed Authentication Service Agency, we can get API from them and use it in our app. It is to be noted that for every request from the app the agencies might charge a little amount.

Below is the code for sending and verifying the otp .

Future<dynamic> sendOtp(String aadhaarNumber) async {

var url = 'https://sandbox.aadhaarkyc.io/api/v1/aadhaar-v2/generate-otp';
final http.Response response = await http.post(Uri.parse(url),
    headers: {
      'Content-Type': 'application/json',
      'Accept': 'application/json',
      'Authorization':
          "Bearer YOUR-API"
    },
    body: jsonEncode({'id_number': aadhaarNumber}));
if (response.statusCode == 200) {
  var dataCard = Aadhaardata.fromJson(json.decode(response.body)["data"]);
  clientID = dataCard.clientId!;
  setState(() {
    showOtpField = true;
  });
  return Aadhaardata.fromJson(json.decode(response.body));
} else {
  throw Exception('Failed to CREATE event: ${response.body}');
}
}

Future<dynamic> validateOtp(String clientId, String otp) async {
var headers = {
  'Content-Type': 'application/json',
  'Authorization':
      'Bearer YOUR-API'
};
var request = http.Request(
    'POST',
    Uri.parse(
        'https://sandbox.aadhaarkyc.io/api/v1/aadhaar-v2/submit-otp'));
request.body = json.encode({"client_id": clientId, "otp": otp});
request.headers.addAll(headers);

http.StreamedResponse response = await request.send();

if (response.statusCode == 200) {
  print(await response.stream.bytesToString());
} else {
  print(response.reasonPhrase);
}
return response.statusCode;
}

This works fine for me .. Contact
