title: How to align flat buttons in flutter?
body: <p>I'm wondering how do I align buttons in flutter. I'm new to flutter and for my current code I'm not able to throw in any rows, column or wrap. I would like to align my buttons in a vertical manner but current its aligned horizontally and giving me a "RIGHT OVERFLOW BY 256 PIXELS" display error</p>
