Redirect to appstore in flutter-CodePudding

I try to launch a link in my apps, so when user click the button it will redirect to appstore. Here is part of the code:

 InkWell(
                                onTap: () =>launchapp(),
                                child: Text(
                                        "Update",
                                        style: TextStyle(
                                            fontSize: 17),
                                      )
                              )

launchapp() async {
    try {
      if (await canLaunch('https://apps.apple.com/app/MyAppName/idXXXXX')) {
        await launch(url);
      } else {
        throw 'Could not launch $url';
      }
    } catch (e) {
      print(e);
    }
  }

I have tried it in my simulator, but always getting

safari cannot open the page because the address is invalid

is there a way to solve this?

You may change DNS server and select manually option. Go to Apple menu then go to System Preferences > Network. some of google Public DNS server example:: 8.8.8.8 8.8.4.4 I had same issue solved this way.

                  }, child: Text('Launch app Button'))
    
                ],

launchapp() async {
    try {
      if (await canLaunch("https://apps.apple.com/app/id$appId")) {
        await launch(url);
      } else {
        throw 'Could not launch $url';
      }

      print(e);
    }
  }

$appId is your appId of App Store.
