I think, there other solution also for same,
You can use showModelBottomSheet as below
showModalBottomSheet(
context: context,
builder: (BuildContext bc) {
return Container();
});
Design Container base on your requirement may you got a solution.

This uses onVerticalDragStart and onVerticalDragUpdate to determine if a pointer moves positionDelta amount in timeDelta time. To trigger it you just have to swipe down fast enough.
int initialDragTimeStamp;
int currentDragTimeStamp;
int timeDelta;
double initialPositionY;
double currentPositionY;
double positionYDelta;
void _startVerticalDrag(details) {
// Timestamp of when drag begins
initialDragTimeStamp = details.sourceTimeStamp.inMilliseconds;
// Screen position of pointer when drag begins
initialPositionY = details.globalPosition.dy;
}
void _whileVerticalDrag(details) {
// Gets current timestamp and position of the drag event
currentDragTimeStamp = details.sourceTimeStamp.inMilliseconds;
currentPositionY = details.globalPosition.dy;
// How much time has passed since drag began
timeDelta = currentDragTimeStamp - initialDragTimeStamp;
// Distance pointer has travelled since drag began
positionYDelta = currentPositionY - initialPositionY;
// If pointer has moved more than 50pt in less than 50ms...
if (timeDelta < 50 && positionYDelta > 50) {
// close modal
}
}
And on your GestureDetector:
GestureDetector(
onVerticalDragStart: (details) => _startVerticalDrag(details),
onVerticalDragUpdate: (details) => _whileVerticalDrag(details)
)
details refers to DragUpdateDetails and passes event information
Keep in mind if the modal includes a ListView or anything else that would block scroll gestures, you'll want to include something like this to keep receiving them.

void _whileVerticalDrag(details) {
// Gets current timestamp and position of the drag event
currentDragTimeStamp = details.sourceTimeStamp.inMilliseconds;
currentPositionY = details.globalPosition.dy;
// How much time has passed since drag began
timeDelta = currentDragTimeStamp - initialDragTimeStamp;
// Distance pointer has travelled since drag began
positionYDelta = currentPositionY - initialPositionY;
// If pointer has moved more than 50pt in less than 50ms...
if (timeDelta < 50 && positionYDelta > 50) {
// close modal
}
}
And on your GestureDetector:
GestureDetector(

)
details refers to DragUpdateDetails and passes event information
