Example

String _platformVersion = 'Unknown';
final _JlOtaPlugin = FlutterJlOta();

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

// Platform messages are asynchronous, so we initialize in an async method.
Future<void> initPlatformState() async {
  print("sn_log => ${'sn_testFirmwareUpgrade 执行了1'}");

  String platformVersion;
  // Platform messages may fail, so we use a try/catch PlatformException.
  // We also handle the message potentially returning null.
  try {
    platformVersion =
        await _JlOtaPlugin.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;
