我无法TextEditingController在 JSON 正文中发布 http 请求，但是如果我直接将字符串传递给 JSON 正文，则相同的代码可以工作
class _FormPageState extends State<FormPage> {
late String name1;
late String email1;
late String phone1;
late String pass1;
late String pass2;
TextEditingController name = new TextEditingController();
TextEditingController email = new TextEditingController();
TextEditingController phone = new TextEditingController();
TextEditingController password = new TextEditingController();
TextEditingController confirmpassword = new TextEditingController();
final GlobalKey<FormState> _formkey = GlobalKey<FormState>();
