Hi, it's my first talking to you, よろしくお願いいたします。

I watched your video demonstrating what the project can do, I have videos showing what I've been doing too

I wrote algorithms for calculating layout, although I think the way to create layout is important after all.
I am using https://github.com/Xyncgas/BlazorCL which has a structure called LDS (Layout_Data_Structure) that has left, top, width, height, which is sufficient to draw a 2D rectangle, while it is familiar to people who are working with the browsers too.
I made this structure with explicit struct layout :

As you can see LDS backed by a Vector4 Memory and inside the structure it has point2d and dimension2d that's backed by Vector too which allows SIMD accelerations when doing calculations

I started doing some tricks, for example I can write codes like this :

Since there isn't a good enough solution that comes with the browser and dotnet to do exactly what I want to do for drawing layout, I found myself having the needs to implement my own layout algorithms, which making it available in csharp for me to draw any layout knowing it's gonna work.

Lastly I would like to share some interesting things I've been doing, notice how I'm using operators in the layout definitions, that lets me say I want to divide a layout to 20 rows and 3 columns and pick the first grid (rectangle) with the syntax such as
LDS MyLayout => LDS.Screen % (3, 20);
And from there I can keep drawing layout in however ways I would like using things like
LDS MyLayout2 => MyLayout ^ (2,-19); To draw another rectangle at the bottom right corner of the screen
And then I can draw another rectangle between them using
LDS MyLayout3 => MyLayout.BR & MyLayout2.TL; To draw another rectangle between two points

During development layouts are generally created not to be directly displayed but to generate other layout that will be used for the elements, this can create a performance problem due to there being a lot function called to create a lot of layout that are depended by the others. This can be mitigated once the UI has been designed, with LDS.Export() and LDS.Import() the final layout can be abstracted to a compile time constant that can be imported later when the layout is being drawn which is going to work the same, while reducing the complexity of the computation to always O(1)

double don't equal to int in :

this cause load MeasureLayout twice, i need convert dp to px.
Target: ConstraintLayout use px to measure and layout, i supply dp method to set property like this api:

I always worry SharpConstraintLayout can't be used in real word, because i don't know the performance, test in core is fast, but in ui, it need calculate more things, i don't know how to test it. I only know, when i resize Windows app, flow test like slow.

Goolgle use androidx.constraintlayout , i believe it meet needs. I try to add a framerate label and a androidx.constraintlayout
flow test to compare with sharpconstraintlayout at a5ec59b, get result:

We can see when resize window of app that run in Windows subsystem for Android, androidx.constraintlayout and sharpconstraintlayout all get low framerate. But when change child, framerate is ok.

Did you find any workaround?

Group set Gone only work at Windows.

This is because when set isVisiable=false, Maui Measure child at windows will get 0, but at android or ios, will get same size with when isVisiable=true.
So we can't rely on Maui measure. i find when widget is Gone, will not measure in AndroidSourceCodeMeasureUseSpecForWindows method so we need let widget change visibility, not only view. For view,widget,constraint is consistent, all need change.

That maybe ConstraintLayout use int and Maui use double, convert they not correct

Description

When use ConstraintCircle, current animation just according to start and finish point calculate, so the motion curve is linear, that not well

Steps to Reproduce

Did you find any workaround?

according to radius and angle to calculate position

Can we have a curl page feature in this beautiful package where user can swipe back and front for book-like applications?
Thank you

Problem:
i update maui example in f2d46a3, a grid split to two part, one part is a constraintlayout, but constraintlayout can't deal with it, because if grid split give a not int value, constraintlayout alway return int, that let layout will infinite loop because result have bias.

For solve this problem, i would try use px as unit when measure and layout in constraintlayout, but set property and fluentlayoytconstraintset use dp, return size to maui a dp value, that will let it not always is int.
