title: Increase tap detection area of a widget?
body: <p>I was wondering if it is possible to increase the "tap area" of a specific widget? </p>
  
  <p>A small example would be a 50 by 50 button. If a user taps anywhere on those 50 by 50 pixels the button's <code>onPressed</code> would be executed. However can I make it so that if a user clicks lets say 5 pixels above the button, its <code>onPressed</code> would still be executed? </p>
  
  <p>I just want to increase this area to provide a better user experience without having to increase the actual size of the button which would make the UI worse. </p>
