title: adding width to drawer in flutter
body: <p>I want to be able to add width to this drawer because it takes up too much of the screen when open and I want to lessen the width a bit, is this possible and  how would I do this?</p>
  
  <p>here is my scaffold</p>
  
  <pre><code>Widget build(BuildContext context) {
  return new Scaffold(
    appBar: new AppBar(
      title: new Text("App Name"),
      centerTitle: true,
    ),
    body: new Center(
    ),
  
    drawer: Drawer(
    child: ListView(
        padding: EdgeInsets.zero,
        children: &lt;Widget&gt;[
        UserAccountsDrawerHeader(
          accountName: Text('Test123') ,
          accountEmail: Text('test@123.com'),
          currentAccountPicture: Image.network('https://images-wixmp-ed30a86b8c4ca887773594c2.wixmp.com/f/a89c3e38-b6f3-48a0-9f9e-df9a0129fb93/daghh5x-4a77b3ec-fd4f-4d17-9f84-5963a8cb5c03.png?token=eyJ0eXAiOiJKV1QiLCJhbGciOiJIUzI1NiJ9.eyJzdWIiOiJ1cm46YXBwOjdlMGQxODg5ODIyNjQzNzNhNWYwZDQxNWVhMGQyNmUwIiwiaXNzIjoidXJuOmFwcDo3ZTBkMTg4OTgyMjY0MzczYTVmMGQ0MTVlYTBkMjZlMCIsIm9iaiI6W1t7InBhdGgiOiJcL2ZcL2E4OWMzZTM4LWI2ZjMtNDhhMC05ZjllLWRmOWEwMTI5ZmI5M1wvZGFnaGg1eC00YTc3YjNlYy1mZDRmLTRkMTctOWY4NC01OTYzYThjYjVjMDMucG5nIn1dXSwiYXVkIjpbInVybjpzZXJ2aWNlOmZpbGUuZG93bmxvYWQiXX0.dWTFMrwnbAbj5TtUp9U_vQsohW7MnkRPymzR5wZQoV8'),
