How to dismiss the sheet manually if there is navigation inside?

[davis33321]

Understand that normally we use Navigator.of(context).pop(); to dismiss the modal sheet.

However in my case, there is navigation inside the modal sheet. So, using Navigator.of(context).pop(); will only return to the previous page of the sheet.

I tried to google and use methods such as Navigator.of(context).popUntil((route) => route.isFirst); but still fail.

Anyone can shed some light on this? Many thanks.

For solving this you need to understand how BuildContext works.

Navigator.of(context) will get you the closest Navigator to the context reference. As you have added a Navigator, it will return that Navigator and not the one you used to push the modal button sheet.

For getting the Navigator you used for pushing the modal, you have different options.

The preferred is to use a key to reference the navigator, you have a great example this:

Otherwise, you can pass a context reference from before the inner new Navigator

showBarModalBottomSheet(
                              expand: true,
                              context: context,
                              backgroundColor: Colors.transparent,
                              builder: (context, scrollController) {
return Navigator(
          onGenerateRoute: (_) => MaterialPageRoute(
            builder: (context2) => Builder(
              builder: (context3) => CupertinoPageScaffold(
                ...
                                children: <Widget>[
                                  GestureDetector(
                                    child: Container(
                                        ...
                                    onTap: () {
                                      // context2 or context3 will return the Navigator inside the modal
                                      Navigator.pop(context);
                                    },
                                  ),


                                 }
                                
                            ),
);

As this is not an issue related to the library, I am going to close the issue, feel free to ask more if you don't manage to solve it.
