Get `LayoutBounds` height and width from static resource in .NET MAUI

Question

I have the following XAML:

<Path Style="{StaticResource squared}"
        AbsoluteLayout.LayoutFlags="All"
        AbsoluteLayout.LayoutBounds="-.2, .2, .3, .3" />

<Path  Style="{StaticResource squared}"
        AbsoluteLayout.LayoutFlags="All"
        AbsoluteLayout.LayoutBounds="1.1, .7, .3, .3" />

<Path Style="{StaticResource squared}"
        AbsoluteLayout.LayoutFlags="All"
        AbsoluteLayout.LayoutBounds="-.1, .9, .3, .3" />

Since the height and width are the same, I was trying to set them via a static resource.

<x:Decimal x:Key="SquareSize">.3</x:Decimal>

However, I don't see a way to use it and pass only the height and width. I have tried something like this:

<AbsoluteLayout.LayoutBounds>
    <Rect>
        <Rect.X>-.2</Rect.X>
        <Rect.Y>.2</Rect.Y>
        <!--No way to assign a static resouce below--> 
        <Rect.Height />
        </Rect>
</AbsoluteLayout.LayoutBounds>

AbsoluteLayout.LayoutBounds needs a Xamarin.Forms.Rectangle object.

You can refer to the following code:

        <x:Double x:Key="myWidth">100</x:Double> 
        <x:Double x:Key="myHeight">100</x:Double>

        <Rectangle x:Key="mRectangle" 
                   WidthRequest="{StaticResource myWidth}"      
                   HeightRequest="{StaticResource myHeight}"
               > 
        </Rectangle>

And bind it as follows:

    <Frame  AbsoluteLayout.LayoutBounds="{Binding mRectangle}" 
            AbsoluteLayout.LayoutFlags="All" BackgroundColor="Yellow">
        
    </Frame>

This is on Xamarin. I was asking about MAUI. In MAUI, it requires the `Microsoft.Maui.Graphics.Rect` mentioned in the question which does not have such bindable properties. – Neville Nazerane Dec 26 '22 at 21:35
Above code can also been used in maui. The usage is similar. – Jessie Zhang -MSFT Dec 27 '22 at 06:41
Not really. Thats what I had explained in the comment above. The `Rect` class in maui doesn't have any bindable properties I could bind `{StaticResource myHeight}` to – Neville Nazerane Dec 27 '22 at 08:03
