title: Flutter: Position MaxLength Counter INSIDE of TextField
body: <p>Is there a way to position the character counter inside the text field in Flutter? I found someone else's question asking about a custom counter and managed to put that in place, but it is still below the field and outside of the field. I would love to place it where the suffix goes but I bet that's not possible. Is there another way to make the counter appear inside the field?</p>
  <p>Thanks in advance!</p>
