Forms 如何在xamarin表单的Flex布局中从一开始对齐项目？

我正在使用xamarin forms V3.3.0。我无法从一开始就对齐flex布局最后一行中的项目。我尝试使用这些属性组合，Direction=“Row”Wrap=“Wrap”JustifyContent=“Center”AlignContent=“Start”AlignItems=“Start”。在下面添加了代码和图片

<FlexLayout Direction="Row"  Wrap="Wrap" Margin="5" JustifyContent="Center"  AlignContent="Start"  AlignItems="Start">
            <BoxView HeightRequest="100" WidthRequest="100" BackgroundColor="Blue" Margin="5"></BoxView>
            <BoxView HeightRequest="100" WidthRequest="100" BackgroundColor="Blue" Margin="5"></BoxView>
            <BoxView HeightRequest="100" WidthRequest="100" BackgroundColor="Blue" Margin="5"></BoxView>
            <BoxView HeightRequest="100" WidthRequest="100" BackgroundColor="Blue" Margin="5"></BoxView>
            <BoxView HeightRequest="100" WidthRequest="100" BackgroundColor="Blue" Margin="5"></BoxView>
            <BoxView HeightRequest="100" WidthRequest="100" BackgroundColor="Blue" Margin="5"></BoxView>
            <BoxView HeightRequest="100" WidthRequest="100" BackgroundColor="Blue" Margin="5"></BoxView>
            <BoxView HeightRequest="100" WidthRequest="100" BackgroundColor="Blue" Margin="5"></BoxView>
            <BoxView HeightRequest="100" WidthRequest="100" BackgroundColor="Blue" Margin="5"></BoxView>
            <BoxView HeightRequest="100" WidthRequest="100" BackgroundColor="Blue" Margin="5"></BoxView>
            <BoxView HeightRequest="100" WidthRequest="100" BackgroundColor="Blue" Margin="5"></BoxView>
            <BoxView HeightRequest="100" WidthRequest="100" BackgroundColor="Blue" Margin="5"></BoxView>
            <BoxView HeightRequest="100" WidthRequest="100" BackgroundColor="Blue" Margin="5"></BoxView>
            <BoxView HeightRequest="100" WidthRequest="100" BackgroundColor="Blue" Margin="5"></BoxView>            
        </FlexLayout>

对于最后一行的这些项目，

JustifyContent=“Center”

显示所有项目都移动到中心

您可以尝试改用

JustifyContent=“Start”

您需要将flexlayout更改为：

<FlexLayout WidthRequest="330" HorizontalOptions="Center"  Wrap="Wrap" Margin="5">

我已经试过了，但我需要在所有设备中保持flex布局的开始和结束的边距相等。在您共享的图像中，右边距大于左边距。然后底部的两个框需要更宽，而FlexLayout不适合您。
