How to change the size of a showModalBottomSheet? [Flutter]

Question

I am using a showModalBottomSheet widget and i want to changed the size so that it occupies about 75% of the screen (by default it seems to be occupying 50%). I tried to follow the documentation but could not find a size property. Could someone suggest me a method to change the size of this widget?

currently looks like this

Answer 1

• MediaQuery in Container or SizedBox
• Flexible, Expanded widgets in Column or Row Widgets
• Wrap, FractionallySizedBox widgets

Choose one of them which one is better for your architecture

       showModalBottomSheet(
          context: context,
          builder: (BuildContext builder) {
            return Container(
              height: MediaQuery.of(context).copyWith().size.height * 0.75,
              child: CupertinoDatePicker(
                initialDateTime: appointmentDate,
                onDateTimeChanged: (DateTime newDate) {
                  if (this.mounted) setState(() => appointmentDate = newDate);
                },
                use24hFormat: true,
                mode: CupertinoDatePickerMode.date,
                isScrollControlled: true,
              ),
            );
          },
        );
