title: How to make a dynamic list where user are prompted to enter text in a Text Form Field and the entered text can be accessed in a list?
body: <p>I'm trying to create a page in a Flutter app where the user can enter input, let's say a Username. The entered username will then be updated to a list that the user can see. It almost works like &quot;Favorites&quot; feature, where a user adds into a Favorites List what they like most.</p>
  <p>The only difference between my intended program and a Favorites List is that a Favorites List has all the entries listed in a list view already and the user just need to click the &quot;Heart&quot; button to added to the Favorites List.</p>
  <p>My program, on the other hand, is intended to have the user Enter the input THEN click on a '+' button to add the entered entry into a Favorites List.</p>
  <p>I hope this is clear enough of what I intend to do. Thank you.</p>
