在Flutter中增加抽屉的宽度

我想能够增加这个抽屉的宽度，因为它在打开时占据了太多的屏幕，我想减少一点宽度，这是可能的，我将如何做到这一点？

这是我的脚手架

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: <Widget>[
      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'),
