You don't need to mark modifier factories as @Composable when you use the Modifier.composed {} builder

[Adam Powell]

being able to omit that and construct modifiers that require composition outside of composition is part of the point of composed {} 🙂

[Kazemihabib1996]

Oh, thank you, I forgot to remove that after I update to composed{} 😅

[Adam Powell]

I spent part of the morning doing the same updates to my own code 😄

@Kazemihabib1996 Is the saveLayer() necessary?

[Kazemihabib1996]

@romainguy
Yeah, the result without it:

shimmerWithoutSaveLayer.mp4

[romainguy]

you could try to just draw an alpha gradient with a multiply or add blend mode

[romainguy]

But yeah if you want to fade out the base content you'll need the layer unfortunately

[Kazemihabib1996]

Yeah, unfortunately, for fade out the base, I need that 😞

[Kazemihabib1996]

@romainguy
There isn't any saveLayer in the CanvasScope, and it handles expensive tasks like allocating Paint it self. The draw functions of it accept a blendMode and we can pass any blendMode to it.
So maybe, it should also handle the expensive saveLayer it self some how 🤔🤔 like what you did with Paint. (I'm not sure just the idea came to my mind after you asked about the saveLayer)

[romainguy]

Well saveLayer is expensive not matter who executes it

[romainguy]

Moving it to CanvasScope wouldn't change anything

[Kazemihabib1996]

Yeah, I was thinking about preventing unnecessary saveLayers. but I don't think it's possible by the way.
