title: How to manage global textScaleFactor in Flutter app properly?
body: <p>Flutter apps react on system large text making all Text widgets really large.
  I want to limit textScaleFactor for Text widgets but I want to do it globally not in each Text widget that I'am using.</p>
  
  <p>Now after enabling large text I got exceptions like</p>
  
  <blockquote>
    <p>flutter: ══╡ EXCEPTION CAUGHT BY RENDERING LIBRARY
    ╞═════════════════════════════════════════════════════════ flutter:
    The following message was thrown during layout: flutter: A RenderFlex
    overflowed by 14 pixels on the bottom.</p>
  </blockquote>
  
  <p>What is proper way to do it? 
  One way is to create some wrapper widget instead of using Text, but maybe it can be solved other way?</p>
