How to open a BasicTextField focused with blinking cursor in it?

Question

I have a BasicTextField in one of my views. I am showing the soft keyboard by default and when I start typing letters on the keyboard, nothing is shown in the BasicTextField, since it has no cursor.

To make my keyboard actions visible, I have to tap into the TextField, to make the cursor visible. Now, whenI tap on the keyboard, I see the result in the BasicTextField.

How can I open the BasicTextField with an active blinking cursor in it?

EDIT: the proposed solution from here did not work for me

val focusRequester = FocusRequester()
val keyboardController = LocalSoftwareKeyboardController.current

//..

    .focusRequester(focusRequester)
    .onFocusChanged {
        if (it.isFocused) {
            keyboardController?.show()
        }
    }

Did neither activated the cursor nor made the keyboard appear. In addition to that

DisposableEffect(Unit) {
    focusRequester.requestFocus()
    onDispose { }
}

leads to a crash:

java.lang.IllegalStateException: FocusRequester is not initialized. Here are some possible fixes:

   1. Remember the FocusRequester: val focusRequester = remember { FocusRequester() }
   2. Did you forget to add a Modifier.focusRequester() ?
   3. Are you attempting to request focus during composition? Focus requests should be made in
   response to some event. Eg Modifier.clickable { focusRequester.requestFocus() }

Answer 1

I got it working:

val focusRequester = FocusRequester()

//..

.focusRequester(focusRequester)

and instead of

DisposableEffect(Unit) {
    focusRequester.requestFocus()
    onDispose { }
}

I used

LaunchedEffect(Unit) {
    if(isFocused){
        focusRequester.requestFocus()
    }
}
