Remove extra space from FlexLayout

I have a FlexLayout with following properties. Whenever any element is added to it(except the first one), extra space gets added automatically at the bottom. How do I get rid of that extra space?

                 var flexLayout = new FlexLayout
                {
                    Wrap = FlexWrap.Wrap,
                    JustifyContent = FlexJustify.Start,
                    AlignItems = FlexAlignItems.Center,
                    AlignContent = FlexAlignContent.Start,
                    BackgroundColor = Color.LightYellow,
                    HorizontalOptions = LayoutOptions.FillAndExpand,
                    VerticalOptions = LayoutOptions.Start
                };

Can't paste image links here with the result. I have posted the same question on StackOverflow with all screenshots, search for Remove extra space from FlexLayout
