java - Flutter在某些设备上无法连接到服务器在Release模式下

Question

我发布了应用程序，但在某些设备上遇到错误 (Android)

在某些设备上，应用程序无法连接到 Web 服务 (API) 来发送或接收信息 Android 版本会出现此问题

我也把 Android Permission 放在了 AndroidManifest 但是它不起作用

设备之一：三星 Galaxy A10 | 安卓 8

此设备已安装此版本：v7a

AndroidManifest.xml：

<manifest xmlns:android="http://schemas.android.com/apk/res/android"
   package="com.example.test">

<uses-permission android:name="android.permission.INTERNET"/>

<uses-permission android:name="android.permission.RECORD_AUDIO"/>

和我的代码：

static Future loginCode(String phone) async {

    String url = 'https://panel.test.ir/api/v1/login_code/lawyer';

    try{
      var response = await http.post(
        url,
        body: {
          "mobile_number": phone
        },
        headers: {
          accept : acceptValue
        }
      ).timeout(Duration(seconds: 30));
      print(response.statusCode);

      var data = jsonDecode(response.body);

      try{
        showToast(data['message']);
      }catch(e){}

      if(response.statusCode == 200){
    
        if(data['new_user'] == null){
          return false;
        }else{
          return true;
        }
  
      }else{
        showError(response);
        return null;
      }
    }catch(e){
      showToast("Send Data Error");
      return null;
    }
}

30秒后，请求会自动取消
