title: How to stack the items inside a "Listview.builder" on top of each other? flutter
body: <p>I want to stack the items inside a <strong>Listview.builder</strong> but when I try to do so with the <strong>Align()</strong> class and set its <strong>heightfactor: ,</strong> it gives padding to the <strong>top</strong> and <strong>bottom</strong> and I don't want that, does anyone have any idea how do I stack them properly?</p>
