Eu rodo o projeto e o content não chega a aparecer no db.json

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

class JornaulService{ static const String url = 'http://192.168.x.xxx:3000/'; static const String resource = 'learnhttp/';

//junta as duas String

String getUrl() { return "$url$resource"; }

//registra algo no banco usando a API register(String content){ //transforma a url que é string e uma uri http.post(Uri.parse(getUrl()), body: { "content": content }); }

}
