title: Flutter InputDecoration floatingLabelStyle font family
body: <p>Is there a way to change font family of a TextField, but keep default input decoration style?</p>
  <p>I set style for TextFormField, but it also changed font family of floating label. So I need to reset it to default value.</p>
  <p>If I use floatingLabelStyle, it will also change color and animation while the field become in focus.</p>
  <pre><code>title: TextFormField(
    style: GoogleFonts.jetBrainsMono(),
    decoration: const InputDecoration(
      labelText: 'Password',
    ),
  ),
  </code></pre>
