How Can I get a List object by HttpClientResponse?
0
How can I get a List object in "result"? I tried with toList() method on "request" object, but I can't solve this.
import 'dart:io';
import 'dart:convert';
void main() async {
var request = await HttpClient().getUrl(Uri.parse('https://jsonplaceholder.typicode.com/posts')); // produces a request object
var response = await request.close(); // sends the request
// transforms and prints the response
var result;
await for (var contents in response.transform(Utf8Decoder())) {
result =contents;
}
print(result);
}
Thanks,
Daniel

Firstly, response.transform return multiple parts of result, you need to get all by joining them together:
var result = new StringBuffer();
await for (var contents in response.transform(Utf8Decoder())) {
result.write(contents);
}
Secondly, you result is just a "text" (in json format), not an "object" as you expect, you need to decode it:
List<dynamic> myList = jsonDecode(result.toString());
print(myList);
