title: How to set border color in jetpack compose BasicTextField?
body: <p>I use <code>BasicTextField</code> from <code>package androidx.compose.foundation.text</code> and it has a default grey field color as visible here:

  <p>I do not want this grey highlight, therefore I want to set the backgroundColor completely to black:</p>
  <pre><code>BasicTextField(
      modifier = Modifier
          .background(Color.Black)
  )
  </code></pre>
  <p>But this does take effect only partially as visible here

  <p>There is a border still having grey color.</p>
  <p>It is ok to keep the border dimensions, but I would like to have a complete black background as here

  <p>How can I manage this?</p>
  <p>Edit: I tried to add a <code>border()</code> modifier with <code>color = Color.Black</code> -  in vain.</p>
