How can I calculate letter spacing depending on the width of the device for a BasicTextField, limiting the number of characters (in my case 8) and the text is to occupy the whole available space?
I tried with the below code but the measured width doesn't seem to return the correct value every single time
var actualTextViewWidth by remember { mutableIntStateOf(0) }
BasicTextField(
modifier =
modifier.fillMaxWidth().onGloballyPositioned {
layoutCoordinates ->
actualTextViewWidth = layoutCoordinates.size.width
},
value = enteredText,
textStyle =
TextStyle(
letterSpacing =
calculateLetterSpacing(actualTextViewWidth, 8).dpToSp,...
fun calculateLetterSpacing(viewWidth: Int, maxCharacters: Int): Int {
val targetTextWidth = viewWidth / (maxCharacters - 1)
return targetTextWidth / (maxCharacters - 1)
}
You are only calculating the letter spacing.
TextField
has letters as well as spaces between letters.Note: Make sure to pass the text style to
rememberTextMeasurer()
as well if you change any style aspects like font size.
