title: Flutter Hero with Text widget that changes style
body: <p>I'm trying to transition a Text Widget between two screens (using Hero widget).
  I'd like the Text Widget to change its style between these two screens (let's say FontSize).</p>
  <p>Implementing it resulting in a strange behavior: the text doesn't change its size smoothly but rather has jerky animation...</p>
  <p>Any idea on how to implement it correctly?</p>
