Connection refused error when creating Http server using dart - flutter

Question

I have created a server using a Plane dart and trying to listen to the response using HTTP get. I can access the response when I ping the I/P in browser but when trying to access in a demo app i get the error
SocketException: OS Error: Connection refused, errno = 111, address = 127.0.0.1, port = 36000
My Server code is as below :
class ServerUtilities {
static Directory _appDirectory;
static HttpServer _server;
static File _file;
ServerUtilities._();
static ServerUtilities _obj;
static ServerUtilities instance() {
if (_obj == null) _obj = ServerUtilities._();
return _obj;
}
Future<Directory> setAppDirectory() async {
return await getApplicationDocumentsDirectory();
}
void initializeServer(String address, int port) async {
_appDirectory = await setAppDirectory();
print(_appDirectory.path);
_file = File('${_appDirectory.path}/sample.txt');
_file.writeAsString("Hiii ", mode: FileMode.append);
_server = await HttpServer.bind(address, port);
print("Server initialized - " + address + ":" + port.toString());
await for (var req in _server) {
if (await _file.exists()) {
print("file exist");
// req.response.headers.contentType = ContentType.text;
await _file.openRead().pipe(req.response);
}
}
}
void stopServer() async {
await _server.close().catchError(
(e) {
print(e);
},
).then(
(value) => {
print("Server stopped "),
},
);
}
}
The server got initialized and everything works fine and can open the provided IP in my mobile browser and it works well but when trying to use Http.get i got the above error.
This is my main.
void main() async {
WidgetsFlutterBinding.ensureInitialized();
ServerUtilities.instance().initializeServer('127.0.0.1', 8010);
runApp(
MaterialApp(
home: MyApp(),
),
);
}
And this is how I am trying to access, And I am getting the above-specified error.
FutureBuilder(
future: http.get("http://127.0.0.1:8010"),
builder: (context, data) {
if (data.hasData)
return Text(
data.toString(),
style: TextStyle(fontSize: 20),
);
else if (data.hasError) {
print(data.error);
return Text(
data.error.toString(),
style: TextStyle(fontSize: 20),
);
} else
return Text(
"No data",
style: TextStyle(fontSize: 20),
);
}),

This error comes when the Server is not running. So please check whether initializeServer method is working correctly or not.
