Functions

Modifier.requiredSize

Cmn 
fun Modifier.requiredSize(size: Dp): Modifier

Declare the size of the content to be exactly sizedp width and height. The incoming measurement Constraints will not override this value. If the content chooses a size that does not satisfy the incoming Constraints, the parent layout will be reported a size coerced in the Constraints, and the position of the content will be automatically offset to be centered on the space assigned to the child by the parent layout under the assumption that Constraints were respected.

See requiredSizeIn to set a size range. See size to set a preferred size, which is only respected when the incoming constraints allow it.

Example usage:

import androidx.compose.foundation.background
import androidx.compose.foundation.layout.Box
import androidx.compose.foundation.layout.requiredSize
import androidx.compose.foundation.layout.size
import androidx.compose.ui.Modifier
import androidx.compose.ui.graphics.Color
import androidx.compose.ui.unit.dp

// The result is a 50.dp x 50.dp red box centered in a 100.dp x 100.dp space.
// Note that although a previous modifier asked it to be 100.dp x 100.dp, this
// will not be respected. They would be respected if size was used instead of requiredSize.
Box(Modifier.requiredSize(100.dp, 100.dp).requiredSize(50.dp, 50.dp).background(Color.Red))
