여러 flutter 페이지에서 공유하는 showModalBottomSheet 함수를 만들 수 있나요?

공유하는 showModalBottomSheet에는 현재 context를 넘겨야 합니다. 예를 들면

void openSharedSheet(BuildContext pageContext) {
    showModalBottomSheet(
        context: pageContext,
        builder: (sheetContext) {
            return Text("Shared bottomSheet");
        },
    );
}

네. 원하는 뷰를 전달할 child 매개변수를 받는 공유 showModalBottomSheet 함수를 정의하세요

///
/// Open the shared modal sheet
///
Future<R?> openSharedModal<R>({
    required BuildContext pageContext,
    required Widget content,
    bool? scrollControlled,
    ShapeBorder? borderShape,
    bool dismissible = true,
}) {
    return showModalBottomSheet<R>(
        isDismissible: dismissible,
        context: pageContext,
        elevation: SheetSettings.elevation,
        barrierColor: SheetPalette.barrier,
        isScrollControlled: scrollControlled ?? true,
        enableDrag: true,
        backgroundColor: SheetPalette.modal.ofContext(_pageContext),
        shape: borderShape ?? SheetSettings.borderShape,
        builder: (BuildContext sheetContext) {
            return content;
        },
    );
}
