Cupertino ActionSheet

https://flutter.dev/docs/development/ui/widgets/cupertino

Cupertino (iOS-style) widgets

showCupertinoModalPopup(
  context: context,
  builder: (BuildContext context) => CupertinoActionSheet(
      title: const Text('Choose Options'),
      message: const Text('Your options are '),
      actions: <Widget>[
        CupertinoActionSheetAction(
          child: const Text('One'),
          onPressed: () {
            Navigator.pop(context, 'One');
          },
        ),
        CupertinoActionSheetAction(
          child: const Text('Two'),
          onPressed: () {
            Navigator.pop(context, 'Two');
          },
        )
      ],
      cancelButton: CupertinoActionSheetAction(
        child: const Text('Cancel'),
        isDefaultAction: true,
        onPressed: () {
          Navigator.pop(context, 'Cancel');
        },
      )),
);

특이한 것은 안드로이드에서 cupertino 디자인이 유지된다는 점이다.

ㅋ 재밌네
