How clear focus for BasicTextField in Jetpack Compose?

Question

I have a Jetpack Compose (Beta04) BasicTextField (with decorationBox). How can I clear the focus?

I have tried with focusRequester but this doesn't works:

val focusRequester = remember { FocusRequester() }

// ...

BasicTextField(modifier = Modifier.focusRequester(focusRequester), /* ... */)

// ...

placesFocusRequester.freeFocus()

To clear focus from the currently focused component you can use the FocusManager.clearFocus method:

    val focusRequester = remember { FocusRequester() }
    val focusManager = LocalFocusManager.current
    var value by rememberSaveable { mutableStateOf("initial value") }
    BasicTextField(
        value = value,
        onValueChange = { value = it },
        decorationBox = { innerTextField ->
            Row(
                Modifier
                    .background(Color.LightGray, RoundedCornerShape(percent = 30))
                    .padding(16.dp)
                    .focusRequester(focusRequester)
            ) {
                //...
                innerTextField()
            }
        }
    )
  
    Button(onClick = { focusManager.clearFocus() }) {
        Text("Clear focus")
    }
