title: How to set different colors for same widget type using ThemeData? [Flutter]
body: <p>I have been trying to find examples and tutorials on how to implement a <code>ThemeData</code> in flutter. Although most of them seem to implement it rather easily, I have not found any examples where one widget type (ex: Text, FlatButton, Card, etc.) are able to have multiple colors at the same time.</p>
  
  <p>In my application, if i have two Strings : "enter tasks here" and "Tasks for this day - ${cardList.length}", is it possible to define a single <code>ThemeData</code> where the first string can use one color and the second string can use a different color?</p>
