在我的flutter应用程序中，我有一个API，可以通过表单从应用程序发送数据。
在我的项目中，有一个对象迭代，我希望用户添加要发送到API的数字输入，这样就会有几个提交按钮来分别发送数据。
目前，我有一个表：

Table(
                                          children: [
                                            const TableRow(children: [
                                              Text(
                                                '',
                                                style: TextStyle(
                                                  fontSize: 15,
                                                  fontWeight: FontWeight.bold,
                                                  color: Colors.black,
                                                ),
                                              ),
                                              Text(
                                                'Size',
                                                style: TextStyle(

                                                ),
                                              ),
                                              Text(
                                                'Order',

                                                  keyboardType:
                                                      TextInputType.number,
                                                  decoration: InputDecoration(),

                                                      TextInputType.number,
                                                  decoration: InputDecoration(),
                                                ),
                                                IconButton(
                                                  icon: Icon(Icons
                                                      .check_circle_outline),
                                                  onPressed: () {
                                                    // Code to execute when button is pressed
                                                  },
                                                )
                                              ])
                                          ],
                                        ),

函数如下：

Future<http.Response> addLog(int id,
      int logOrder, int logSize) async {
    var url = Uri.parse(Config.apiURL +
        Config.userAddlogAPI.replaceFirst("{id}", id.toString()));

    final response = await http.post(url, headers: {
      HttpHeaders.authorizationHeader:
          'Token xxxxxxxxxxxxx',
    }, body: {
      'log_Order': logOrder,
      'log_Size': logSize,
    });

    if (response.statusCode == 200) {
      // request was successful, parse the response
      return response;
    } else {
      // request failed, check the status code and response body for more information
      throw Exception("Failed to add log");
    }
  }

我的问题是如何创建一个表单，以便发送在TextField中接收到的数值。
