what is the attribute of the moddifier that i need to change to make the corners rouned and the width a little smaller? jetpack Compose

Question

my question is different from the suggested question that is similar because I am making the voting bar change in effect from the parameters of the voting percentage. therefore I need the left column to change dynamically in size and the right column to change dynamically in size therefore I find it difficult to implement with a Stroke object.

what is the attribute of the modifier that I need to change to make the corners round? and the width a little smaller of a Row() element

I am trying to make an android app with jetpack compose, in the process of implementing the Voting bar which is the bar in the middle with the 2 colors of red and blue. I can't find the correct attribute to modify so the corners of the bar will be rounded and make the width different from .fillMaxWidth() in the modifier so I ended up using it until I will find a solution. if you have any insights :) thanks in advance ~!

            Spacer(modifier = Modifier.width(10.dp))
            Text(
                text = "Right $rightyPercent%", fontSize = 20.sp, fontWeight = FontWeight.Bold
            )
        }

        Row() {
            Box(
                modifier = Modifier
                    .size(30.dp)
                    .clip(CircleShape)
                    .background(Color(0xFF03588C))
            )
            Spacer(modifier = Modifier.width(10.dp))
            Text(
                text = "Left $leftyPercent%", fontSize = 20.sp, fontWeight = FontWeight.Bold
            )
        }


    }

}

I followed the 5 steps tutorial at the leading developer's website but I fill still a beginner.

Answer 1

You can wrap the 2 Row in a Column applying a padding modifier (to avoid the full width) and an horizontalAlignment.
Then in the 1st Row apply a clip modifier to achieve the rounded shape.

Something like:

val shape = RoundedCornerShape(32.dp)

Column(
    Modifier.padding(16.dp),
    horizontalAlignment= Alignment.CenterHorizontally
) {
    Row(
        modifier = modifier
            .fillMaxWidth()
            .height(32.dp)
            .background(Color.White)
            .clip(shape)
            .border(1.dp, Color.Black, shape)
    ) {
        Column(
            // add rounded corners to the left side
            modifier = Modifier
                .background(Color(0xFFA60321))
                .weight(leftyPercentWeight)
                .clip(CircleShape),
            verticalArrangement = Arrangement.Center,
            horizontalAlignment = Alignment.CenterHorizontally

        ) {

        }
        Column(
            modifier = Modifier
                .background(Color(0xFF03588C))
                .weight(rightyPercentWeight)
                .clip(CircleShape),
            verticalArrangement = Arrangement.Center,
            horizontalAlignment = Alignment.CenterHorizontally
            // add rounded corners to the right side
        ) {}
    } 
    //2nd Row

}
