flutter web mis-spelled word indication in textfield (red squiggly line)

Question

As far as I can tell, there is no spell checker currently for Flutter web. Therefore, I'm trying to experiment using a simple spell checker package (https://pub.dev/packages/spell_checker) along with a list of English words (https://pub.dev/packages/english_words)

However, the final piece that I'm missing is a way to show some kind of underline under the mis-spelled words. That is, how to change the style of the text input by the user in an 'TextField()' widget to show errors.

How can I manipulate that text in the textfield()?
