adding width to drawer in flutter

Wrap the Drawer widget inside a Container widget and pass the width parameter to the Container.

drawer: Container(
      width: 50,
      child: Drawer(
        child: ListView(
          padding: EdgeInsets.zero,
          children: <Widget>[
            UserAccountsDrawerHeader(
              accountName: Text('Test123'),
              accountEmail: Text('[email protected]'),
              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'),
            ),
            ListTile(
              title: Text('data'),
            ),
          ],
        ),
      ),
    ),

Here is another example to give width to the Drawer.

return SizedBox(
  width: MediaQuery.of(context).size.width * 0.75, // 75% of screen will be occupied
  child: Drawer(
    
  ),
);

Thank you.
