Low level

Here is the await for version of collecting the response stream. It's a little more compact than using a completer.

Future readResponse(HttpClientResponse response) async {
  final contents = StringBuffer();
  await for (var data in response.transform(utf8.decoder)) {
    contents.write(data);
  }
  return contents.toString();
}

You should wrap it in a try catch block to handle errors.

High level

Most of the time from the client side you would use the http library instead:

// import 'package:http/http.dart';

Response response = await get(url);
String content = response.body;
