          builder: (context) => AlertDialog(
            content: DetailsScreen(),
            actions: [
              IconButton(
                onPressed: () {
                  Navigator.of(context).pop();
                },
                icon: const Icon(
                  Icons.close,
                  color: Colors.redAccent,
                ),
              )
            ],

Answer 1

I think you have context issue. When user click to open secound dialog you should pop first dialog then you should open secound dailog. For pop first dailog you should use :-

Navigator.pop(firstDialogContext);
