'horizontalArrangement not working in Jetpack Compose

I have tried applying SpaceBetween, SpaceEvenly and SpaceAround but nothing seems to be working here. My main goal here is to put the iconButton and the text on the start and end of the same row. Please don't refer to me appbar for doing so I just want to know why this is not working and what is the fix?

enter image description here

        Row(
            modifier = Modifier.padding(30.dp),
            horizontalArrangement = Arrangement.SpaceBetween
        ){

            Text(
                "NOTES",
                fontSize = 30.sp,
                fontWeight = FontWeight.Bold,
                color = Color.White
            )

            IconButton(onClick = { /*TODO*/ }) {
                Icon(
                    Icons.Filled.Search,
                    contentDescription = "Search",
                    tint = Color.LightGray
                )

            }

        }


Solution 1:[1]

Add the modifier fillMaxWidth() in your Row

Row(
    modifier = Modifier.fillMaxWidth(),
    horizontalArrangement = Arrangement.SpaceBetween
){
   //....your content
}

enter image description here

Solution 2:[2]

In the Row modifier use fillMaxWidth()

Row(
    modifier = Modifier
        .fillMaxWidth()
        .padding(30.dp),
    horizontalArrangement = Arrangement.SpaceBetween
)
