电话号码返回 null

Question

我在使用 flt_telephony_info flutter 插件获取用户电话号码时遇到问题，即使在 AndroidManifest.xml 中添加了必要的权限，该值仍然返回 null。按照下面的代码。

//AndroidManifest.xml

   <uses-permission android:name="android.permission.READ_PHONE_STATE"/>
   <uses-permission android:name="android.permission.ACCESS_NETWORK_STATE"/>
   <uses-permission android:name="android.permission.MODIFY_PHONE_STATE"/>
   <uses-permission android:name="android.permission.READ_SMS"/>
   <uses-permission android:name="android.permission.READ_PHONE_NUMBERS"/>

//main.dart
   TelephonyInfo _info;

   Future<void> getTelephonyInfo() async {
      TelephonyInfo info;
      try {
         info = await FltTelephonyInfo.info;
      } on PlatformException {}
  
      if (!mounted) return;

      setState(() {
         _info = info;
      });
   }

  @override
  void initState() {
    super.initState();
    getTelephonyInfo();
  }

  @override
  Widget build(BuildContext context) {
    return MaterialApp(
      home: Scaffold(
        appBar: AppBar(
          title: const Text('Test'),
        ),
        body: Center(
          child: Text('Phone Number: ${_info?.line1Number}\n'),
        ),
      ),
    );
  }
}

这是回报：

有人可以帮我吗？
