Flutter web http request badCertificateCallback

Question

I was wondering if any you can point me to a web flutter library that had http badCertificateCallback. I tried DIO but it is giving me an error and submit an issue but I haven't heard from them yet

DIO code:

Dio dio = new Dio(options);
(dio.httpClientAdapter as DefaultHttpClientAdapter).onHttpClientCreate =
(client) {
client.badCertificateCallback =
(X509Certificate cert, String host, int port) => true;
};

Error: Expected a value of type 'DefaultHttpClientAdapter', but got one of type 'BrowserHttpClientAdapter'

I also tried http, but it doesn't have a bad Certificate Callback, we could use this but it isn't web-compatible

HttpClient httpClient = new HttpClient();
    httpClient.badCertificateCallback =
        ((X509Certificate cert, String host, int port) => true);
    IOClient ioClient = new IOClient(httpClient);
response = await ioClient.post(url, body: data, headers: headers);

Any comment will be more that apreciate.

Thanks in advance, Daniel

Solution

Make a http Client like this,

import 'dart:convert';
import 'dart:io';
import 'package:dio/adapter.dart';
import 'package:dio/dio.dart';
import 'package:flutter/foundation.dart';
import 'dart:io' as IO;
....
....
....
/// CLIENT
static Future<Dio> _dioClient() async {

Dio dio = Dio(await _getOptions()); // Getting Headers and Other data

if(!kIsWeb){
  (dio.httpClientAdapter as DefaultHttpClientAdapter).onHttpClientCreate =
      (IO.HttpClient client) {
    client.badCertificateCallback =
        (X509Certificate cert, String host, int port) => true;
    return client;
  };
}
return dio;                                                             
}
