Question

How can I draw a text on a compose canvas I don t see any `drawText` method in the `DrawScope`

jim · Answer

Nader Jawad · Answer

Drawing text is fairly involved and we find that generally speaking the drawText API is a little too simplistic while the text APIs in compose are easier to interact with than the current framework equivalent You can either leverage the native API as Jim suggests or have a separate text composable on top

Adam Powell · Answer

How would you want such an overload to behave

Dominaezzz · Answer

Just a draw function that takes a composable As supposed to an overload

Dominaezzz · Answer

I expect the function to pass down the transformations and draw the composable in a specified bound

Dominaezzz · Answer

I m happily assuming that all drawing happens on a `Canvas`

That sounds like the `drawWithContent` modifier or whatever replaced it since it s deprecated

Dominaezzz · Answer

Oh Like ```Canvas drawWithContent ```

Dominaezzz · Answer

Ohhh `Modifier` lol I misread

Zach Klippenstein (he/him) [MOD] · Answer

```Text Modifier drawWithContent withRotate withScale Actually draws the modified composable drawContent ```

Dominaezzz · Answer

Woah That s pretty cool

Dominaezzz · Answer

Although pretty strange thing to have as a `Modifer` I think Since you can t have multiple components in the canvas

Zach Klippenstein (he/him) [MOD] · Answer

What would that api look like As soon as you ve got multiple composables the canvas would probably need to implement some sort of layout system and then you d be basically just re implementing compose again

Zach Klippenstein (he/him) [MOD] · Answer

I think you could achieve something like that using `SubcomposeLayout` layout all your non canvas children first place them then subcompose your canvas composable underneath them all passing their locations Similar to how `SimpleTableLayout` works here <https github com zach klippenstein compose richtext blob main richtext ui src main java com zachklipp richtext ui SimpleTableLayout kt>

Adam Powell · Answer

do you need subcomposition for that Drawing happens well after layout If you want to publish layout locations to some drawing code that consumes it you don t need subcomposition for that

Zach Klippenstein (he/him) [MOD] · Answer

I was thinking if you wanted to pass the locations to a composable function as parameters But that s not the only way to do it for sure
