我正在尝试用Flutter登录。我正在咨询Web服务。我想在Post请求的正文中发送来自不同TextFormField的用户名和密码。我怎样才能做到这一点？这是我一直在努力的代码。

import 'package:flutter/material.dart';
import 'package:device_id/device_id.dart';
import 'package:http/http.dart' as http;

import 'dart:async';
import 'dart:convert';


class SignIn extends StatefulWidget {
  @override
  _SignInState createState() => _SignInState();
}

class _SignInState extends State<SignIn> {
  Future<String> getData() async {
    final response = await http.post(
        Uri.encodeFull("The route i'm consulting),
        body: {
          "username": user,
          "password": password
        },

我想从此处的用户名和密码TextFormField检索输入文本

        headers: {
          "Accept": "application/json",
        });
    print(response.statusCode);
    print(response.body);
  }

  String _deviceid = 'Unknown';
  String user = '';
  String password = '';

  TextEditingController controller = new TextEditingController();
  TextEditingController controller2 = new TextEditingController(); …
