Unhandled Exception: 'package:flutter/src/widgets/scroll_controller.dart': Failed assertion: line 201 pos 12: '_positions.isNotEmpty': ScrollController not attached to any scroll views.

GestureDetector(
onLongPressUp: () {
showCupertinoModalBottomSheet(
isDismissible: true,
backgroundColor: lightBlackNavBar,
useRootNavigator: true,
context: context,
duration: Duration(milliseconds: 200),
builder: (context) => Container(
height: 300,
child: Center(child: Text('I tuoi account')),
),
);
},

I'm trying to open the bottom modal sheet but when I tap outside to dismiss the bottom sheet it throws the error:

[ERROR:flutter/runtime/dart_vm_initializer.cc(41)] Unhandled Exception: 'package:flutter/src/widgets/scroll_controller.dart': Failed assertion: line 201 pos 12: '_positions.isNotEmpty': ScrollController not attached to any scroll views.
