Question

How to set elevation for material3 card? I am using new material3 card and getting error

This material API is experimental and is likely to change or to be removed in the future.

Here is code ->

    @ExperimentalMaterial3Api
    @Composable
    fun ProfileCard(
        modifier: Modifier = Modifier
    ) {
        Card(
            modifier = modifier
                .fillMaxWidth()
                .wrapContentHeight()
                .padding(all = 16.dp),
            shape = RoundedCornerShape(size = 16.dp),
            containerColor = MaterialTheme.colorScheme.surface,
            border = BorderStroke(width = 1.dp, color = MaterialTheme.colorScheme.inverseOnSurface),
            elevation = CardDefaults.outlinedCardElevation()
        ) {
    ...
        }
    }

I am not able to run app due to error caused by elevation how to set elevation?

Edit : Solved the issue by adding

elevation = CardDefaults.outlinedCardElevation(defaultElevation = 1.dp)

Why do we have to add border for CardDefaults.outlinedCardElevation why does't it show by default?

Answer 1

If you find the same message in the future for another reason, one option could be to add in your build.gradle file, the following:

kotlinOptions {
    allWarningsAsErrors = false
    freeCompilerArgs += [
        '-opt-in=androidx.compose.material3.ExperimentalMaterial3Api'
    ]
}

In this way, after Sync Project with Gradle Files you will not see the warnings in your compose code.
