Dart BLE 描述以便于编码？

问题描述

一个架构问题： 我有一个带有许多变量的 BLE 设备......并且可以从 XML 中引入这些变量，例如

<!--Automation IO-->
  <service advertise="false" id="automation_io" name="Automation IO" requirement="mandatory" sourceId="BLE" type="primary" uuid="1815">
    <informativeText>Abstract:  The Automation IO service is used to expose the analog inputs/outputs and digital input/outputs of a generic IO module (IOM).  </informativeText>
    
    <!--Output-->
    <characteristic id="Output" name="Output" sourceId="xxx" uuid="1230">
      <informativeText>Summary:  The Digital characteristic is used to expose and change the state of an IO Module's digital signals.  </informativeText>
      <value length="1" type="user" variable_length="false">0</value>
      <properties indicate="false" indicate_requirement="optional" notify="true" notify_requirement="optional" read="true" read_requirement="optional"/>
    </characteristic>
        
    <!--Electronicstemp-->
    <characteristic id="Electronicstemp" name="Electronicstemp" sourceId="xxx" uuid="1235">
      <informativeText>Summary:  The Digital characteristic is used to expose and change the state of an IO Module's digital signals.  </informativeText>
      <value length="2" type="user" variable_length="false">23</value>
      <properties notify="true" notify_requirement="mandatory" read="true" read_requirement="mandatory"/>
    </characteristic>
    
    <!--MaxElectronicstemp-->
    <characteristic id="MaxElectronicstemp" name="MaxElectronicstemp" sourceId="xxx" uuid="123E">
      <informativeText>Summary:  The Digital characteristic is used to expose and change the state of an IO Module's digital signals.  </informativeText>
      <value length="2" type="user" variable_length="false">23</value>
      <properties notify="true" notify_requirement="mandatory" read="true" read_requirement="mandatory"/>
    </characteristic>
    
    <!--SelfTest-->
    <characteristic id="SelfTest" name="SelfTest" sourceId="xxx" uuid="1236">
      <informativeText>Summary:  The Digital characteristic is used to expose and change the state of an IO Module's digital signals.  </informativeText>
      <value length="1" type="user" variable_length="false">00</value>
      <properties indicate="false" indicate_requirement="optional" notify="true" notify_requirement="optional" read="true" read_requirement="optional" write="true" write_no_response="true" write_no_response_requirement="optional" write_requirement="optional"/>
    </characteristic>
 ...

问题是如何将它变成最适合 FlutterBlue 等的东西。

现在我有

class Intercom{
  static const PatchTo = "665c1cbc-2c88-4ae1-9ccf-9dbc8a9e5440";
  static const PhoneBook = "78805e56-f8b7-4f30-a056-2ece9f4f70a9";
  static const AllCall = "2ac8";
  static const StatusWord = "1239";
...
}

{
    BluetoothCharacteristic patchto =
        bleFindChar(services,Intercom.PatchTo)!;
    await patchto.write([0xFF,0xFF]);
}

---

所以问题： 最好保持这种方式 - 这样我就可以向 Class Intercom 添加越来越多的内容（如数据格式、tostring 等）...

还是分开？

也许 Intercom 应该从 FlutterBlue 派生出来并吸收所有东西，这样我就可以轻松地说 Intercom.PatchTo(0xFFFF) ？

有没有办法将 XML 文件加载到 Flutter 项目中并将其自身呈现为数据结构，或者我是否需要编写一个小的 Python 脚本来获取 XML 并从中制作一个 .dart 文件？

解决方法

xml 包允许您在 Dart（和 Flutter）中解析、遍历、查询、转换和构建 XML 文档。包描述中的教程解释了如何加载 XML 文件和提取数据。欢迎在 StackOverflow 或 GitHub 上发布更具体的问题。
