title: how to build multiple apps with slightly different UI from one project in flutter
body: <p>My query is how can we build multiple apps with different UI's from one project.
  Example:</p>
  <p><code>HomePage</code> has (<code>home1, home2, home3</code>) 3 different Ui's , i want to add <code>home1</code> for one app,  <code>home2</code> for other app and so on.</p>
  <p>So that i can create similar apps with slightly different UI.</p>
  <p>How can we configure the same in flutter?</p>
  <p>Any help would be appreciated.</p>
