How to get response body with request.send() in dart

Just use http.Response.fromStream()

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

var streamedResponse = await request.send()
var response = await http.Response.fromStream(streamedResponse);

I checked the docs for request.send I returns Future<StreamedResponse> instead of Future<Response>

Digging more for StreamedResponse I found that it response.stream which is a ByteStream

Here is what you can do to get response in String

final response = await request.send();
final respStr = await response.stream.bytesToString();

In my opinoin you should only use request.send if you want streamed response instead of "collected" response. More about streams in dart here
