令人敬畏的对话框未在颤振应用程序中关闭

Question

I am using the Awesome Dialog in my flutter application but when I click on OK it just navigates to another screen and doesn't close. here is my code.

    Future requestSupport(String userid, String supportType, String duration) async {
        final response =
  await http.post('http://url/api/Support',
  headers: {"Content-Type": "application/json", 
             'Accept': 'application/json',},
  body: json.encode({'userid' : userid ,  'supportType' : supportType, 'duration' : duration}));

 if (response.statusCode == 200) {

 showAlertDialogOnOkCallback();  

    }



 }
 void showAlertDialogOnOkCallback() {
        AwesomeDialog(
              context: context,
              animType: AnimType.LEFTSLIDE,
              dialogType: DialogType.SUCCES,
              tittle: 'Success',
              desc:
                  'You have been entered into the queue, press OK to go back.',
              btnOkOnPress:  () {  },
              btnOkIcon: Icons.check_circle,
              onDissmissCallback: () {
                debugPrint('Dialog Dissmiss from callback');
              }).show();
 }

  }

Although doc for this library says,

Function that handle click of positive Button, closing the dialog is handled internally.

---

UPDATE : I have tried it myself and it works fine approach I used, I took a button to open dialog,

     RaisedButton(
          child: Text("ok",),
          onPressed: () {
              open();
          },
        ),

Since dialog closing is handled by default by the library I used Navigator.pop(context); this to go back to the previous screen using btnOkOnPress

  void open() {
    AwesomeDialog(
        context: context,
        dialogType: DialogType.INFO,
        animType: AnimType.BOTTOMSLIDE,
        tittle: 'Dialog Title',
        desc:
            'Dialog description here',
        btnCancelOnPress: () {},
        btnOkOnPress: () {
          Navigator.pop(context);
        }).show();
  }

Note: I navigate to screen which is having dialog by Navigator.pushNamed . So if Navigator.pop(context); is called it comes back to this screen only.

Navigator.pushNamed(context, RouteName.ReportScreen);

I am unable to replicate your issue. I used a simple RaisedButton upon tapping on it opens AwesomeDialog . Then tapping on OK button of the dialog closes it properly. I also tested by adding a navigation upon ok button tap that closes the dialog and navigates to next screen. Code I used:

body: Center(
        child: RaisedButton(
          onPressed: () {
            _openDialog();
          },
          child: Text('Tap')
        )
      )

void _openDialog() {
    AwesomeDialog(
        context: context,
        animType: AnimType.LEFTSLIDE,
        dialogType: DialogType.SUCCES,
        tittle: 'Success',
        desc:
        'You have been entered into the queue, press OK to go back.',
        btnOkOnPress:  () {
          Navigator.push(context, MaterialPageRoute(builder: (context) => PageB()));
        },
        btnOkIcon: Icons.check_circle,
        onDissmissCallback: () {
          debugPrint('Dialog Dissmiss from callback');
        }).show();
  }

Console output:

I/flutter (13279): Dialog Dissmiss from callback
I/flutter (13279): Dialog Dissmiss from callback

Hope this helps.

I am trying to use the Awesome Dialogue and then use the property "useRootNavigator" and set it to true.

AwesomeDialog(
        useRootNavigator: true,
        context: context,
        animType: AnimType.LEFTSLIDE,
        headerAnimationLoop: false,
        dialogType: DialogType.SUCCES,
        title: 'Go',
        desc: 'Continue Adding ',
        btnOkOnPress: () {
          Navigator.push(
              context, MaterialPageRoute(builder: (context) => Page2()));
        },
        btnOkIcon: Icons.receipt,
        onDissmissCallback: () {
          debugPrint('Dialog Dissmiss from callback');
        },
        btnOkText: "Add More members",
        btnCancelOnPress: () {
          Navigator.push(
              context, new MaterialPageRoute(builder: (context) => Home()));
        },
        btnCancelIcon: Icons.home,
        btnCancelText: "Go to Home Page")
      ..show();
