Below is my Compose UI Code.
Card(Modifier.height(150.dp)
.weight(1.0F)) {
Box (modifier = Modifier.fillMaxSize(), contentAlignment = Alignment.Center){
Text(text = "A", fontSize = 130.sp)
}
}
Below is how UI look, Consider this code for the Compose Multiplaform not only to the android
We can see that the letter A is not centered inside the Card view.

Thanks to @Bylazy
I change my code and it's working now.
