Hi, stumbled upon a weird bug it seems. Inside TextAutoSizeLayoutScope the function performLayout will ignore the string specified to it to lay out and will always use the one of the TextField to which this TextAutoSize was added.

val text1 = AnnotatedString("labas")
val layoutResult = performLayout(constraints, text1, currentPx.toSp())
println(layoutResult) // TextLayoutResult(layoutInput=TextLayoutInput(text=Timetable...

This API seems surprising: It makes sense that it might want to constraint the autosize logic to only operate on the passed string, but then performLayout shouldn't have that parameter at all.

Exactly, should I file a bug report?

That text parameter surprised me as well

For my use case I actually want it to perform layout on the text specified in the parameter

Looked into it more, the constraints passed to the performLayout function are also completely ignored. So this function only looks at parameters from the main getFontSize function:

override fun TextAutoSizeLayoutScope.getFontSize(
        constraints: Constraints,
        text: AnnotatedString
    ): TextUnit

getFontSize will also always return whatever fontsize was last used in the performLayout function:

performLayout(constraints, text, 45.sp)
return 0.sp // In the end, getFontSize will still return 45.sp
