我还在努力适应颤动。我有一个用户的注册表，当用户单击按钮时，我希望所有文本都发送到我的link.But接口。有没有简单的方法可以做到这一点？或者我应该一个接一个地发短信？我的文本不应该是空的。我怎么才能提供这个呢？

我将在将来调用我的api，并且我想发送用户将在此处输入我的数据的文本。

        Future<RegisterComplete> createRegisterComplete(
        String email, String language) async {
      final http.Response response = await http.post(
        'MY API URL',
        headers: <String, String>{'Content-Type': 'application/json'},
        body: jsonEncode(<String, String>{
          'firstName': ' ',
          'lastName': ' ',
          'password': ' ',
          'countryCode': ' ',
          'language': ' ',
        }),
      );
      if (response.statusCode == 201) {
        return RegisterComplete.fromJson(json.decode(response.body));
      } else {
        print('Here:${response.statusCode}');
        throw Exception('Failed to load page');
      }
    }
    
    class RegisterPage extends StatefulWidget {
   
      @override
      _RegisterPageState createState() => _RegisterPageState();
    }
    
    class _RegisterPageState extends State<RegisterPage> {
      Future<ConfirmCode> _confirmCode;
      var textFieldPasswordController = TextEditingController();
      var textFieldConfirmPasswordController = TextEditingController();
 var cityController=TextEditingController();
  var nameController=TextEditingController();
  var surnameController=TextEditingController();
    
      @override
      Widget build(BuildContext context) {
        return Scaffold(
          body: SafeArea(

首先。

这个方法应该包含var data，它将成为你身体的处理器。

如下所示：

Future<RegisterComplete> createRegisterComplete(
    String email, String language, var data) async {
  final http.Response response = await http.post(
    'MY API URL',
    headers: <String, String>{'Content-Type': 'application/json'},
    body: jsonEncode(data),
  );
  if (response.statusCode == 201) {
    return RegisterComplete.fromJson(json.decode(response.body));
  } else {
    print('Here:${response.statusCode}');
    throw Exception('Failed to load page');
  }
}

现在，这允许您实际包装来自TextEditingControllers的所有数据，因此您可以执行以下操作：

child: InkWell(
                        onTap: () async {
                          setState(() {
                          var data = {
                            'firstName': nameController.text,
'lastName': lastNameController.text,
          'password': passwordController.text,
          'countryCode': countryCodeController.text,
          'language': languageController.text,

                          }

// here you do an actual API call
   await createRegisterComplete(emailController.text, languageController.text, data);


                          });
                        },
