Request all things about a specified channel

Sending it as a query string argument (aka in the url) is deprecated like Kraken/v5 and is generally speaking bad practice (for when you move on to oAuth’ed requests)

Add authorization headers

The http package provides a convenient way to add headers to your requests. Alternatively, use the HttpHeadersclass from the dart:io library.

content_copy

Future<http.Response> fetchPost() {
  return http.get(
    'https://jsonplaceholder.typicode.com/posts/1',
    // Send authorization headers to the backend.
    headers: {HttpHeaders.authorizationHeader: "Basic your_api_token_here"},
  );
}

class UserAgentClient extends http.BaseClient {
  final String userAgent;
  final http.Client _inner;

  UserAgentClient(this.userAgent, this._inner);

  Future<StreamedResponse> send(BaseRequest request) {
    request.headers['user-agent'] = userAgent;
    return _inner.send(request);
  }
}

import 'dart:html';
import 'dart:convert';
void main() {
  var data = { 'title' : 'My first post' };
  HttpRequest.request(
    'https://jsonplaceholder.typicode.com/posts',
    method: 'POST',
    sendData: json.encode(data),
    requestHeaders: {
      'Content-Type': 'application/json; charset=UTF-8'
    }
  )
  .then((resp) {
    print(resp.responseUrl);
    print(resp.responseText);           
  });
}

Seem to be relevant (google hits 1 and 2 and 3 for how to send a header)

No idea if any of these work, this is not a Dart Support forum.
