After giving permission Imei number is not fetching in android version 10 and above

[vrustipatel]

@override void initState() { super.initState(); // if (PreferenceManagerUtils.getIsImeiNumber() == "") { initPlatformState(); _setPlatformType(); checkPermissionAndAccessIMEI(); // } }

    });
  }
}

}

// Platform messages are asynchronous, so we initialize in an async method. Future initPlatformState() async { String platformVersion; // Platform messages may fail, so we use a try/catch PlatformException. // We also handle the message potentially returning null. try { platformVersion = await _deviceImeiPlugin.getPlatformVersion() ?? 'Unknown platform version'; } on PlatformException { platformVersion = 'Failed to get platform version.'; }

// If the widget was removed from the tree while the asynchronous platform
// message was in flight, we want to discard the reply rather than calling
// setState to update our non-existent appearance.
if (!mounted) return;

setState(() {
  _platformVersion = platformVersion;
});

}

Here is my code and also I have given permission in manifest file

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