Digest Authentication not working with HttpClient - flutter

Question

I have used all approaches to Post data using digest authentication but it is not working?
HttpClient authenticatingClient = HttpClient(); authenticatingClient.addCredentials( Uri.parse( 'http://202.142.0000', ), 'aa',=>realm HttpClientDigestCredentials('admin', 'admin'), ); clients = https.IOClient(authenticatingClient); clients .post( Uri.parse( 'http://202.142.0000', ), headers: {'Content-Type': 'application/json'}, body: json.encode({ "Protocol": "a[enter image description here][1]", "Packets": [ { "Id": 1, "Type": "PumpGetStatus", "Data": {"Pump": 1} } ] }), ) .then((value) { print(value.headers); });

Try this code and report the results.
You'll be aiming for the code shown in main (which uses pre-authentication, as long as you know the realm in advance). Somehow, I'm guessing that aa isn't the valid realm.
The code in main2 can be substituted temporarily. Even though it will definitely fail, it will print out the realm, etc. to confirm the true values.
import 'dart:convert';
import 'dart:io';
import 'package:http/http.dart' as http;
import 'package:http/io_client.dart' as ioc;
void main() async {
final postMap = {
'Protocol': 'o',
'Packets': [
{
'Id': 1,
'Type': 'PumpGetStatus',
'Data': {'Pump': 1}
}
]
};
final uri = Uri.parse('http://202.142.x.x');
final authenticatingClient = HttpClient();
authenticatingClient.addCredentials(
uri,
'aa', // is this actually the realm, or is it a guess?
HttpClientDigestCredentials('admin', 'admin'),
);
http.Client client = ioc.IOClient(authenticatingClient);
final response = await client.post(
uri,
headers: {'Content-Type': 'application/json'},
body: json.encode(postMap),
);
print(response.statusCode);
print(response.body);
client.close();
}
void main2() async {
final postMap = {
'Protocol': 'o',
'Packets': [
{
'Id': 1,
'Type': 'PumpGetStatus',
'Data': {'Pump': 1}
}
]
};
final uri = Uri.parse('http://202.142.x.x');
final authenticatingClient = HttpClient();
authenticatingClient.authenticate = ((u, s, r) async {
print('uri=$u scheme=$s realm=$r');
return false;
});
http.Client client = ioc.IOClient(authenticatingClient);
final response = await client.post(
uri,
headers: {'Content-Type': 'application/json'},
body: json.encode(postMap),
);
print(response.statusCode);
print(response.body);
client.close();
}
