How to make HTTPS request using HttpClient in dart?

Question

I'm using HttpClient from dart (dart:io package, NOT dart:http) and I'd like to send an HTTPS request. Is there a way to do that? I can't seem to find a method that would allow me that.

Answer 1

new HttpClient().getUrl(Uri.parse('https://www.somedomain.com'));

Answer 2

The steps of sending HTTPS request is the same as HTTP in dart/flutter, one thing you have to add is to allow self signed certificates to handle badCertificateCallback, add this to your HttpClient:

var httpClient = HttpClient();
      httpClient.badCertificateCallback =
          ((X509Certificate cert, String host, int port) =>
              true); // Allow self signed certificates

Answer 3

HttpClient client = new HttpClient();
client.getUrl(Uri.parse("http://www.example.com/"))
    .then((HttpClientRequest request) {
      // Optionally set up headers...
      // Optionally write to the request object...
      // Then call close.
      ...
      return request.close();
    })
    .then((HttpClientResponse response) {
      // Process the response.
      ...
    });
