I'm using drawer widget...

But there's a white space in the container to the right side...

And here's my code...

home.dart

class Home extends StatelessWidget {
  const Home({Key? key}) : super(key: key);

  @override
  Widget build(BuildContext context) {

    return Scaffold(
      appBar: AppBar(
        title: const Text('Dashboard'),
        elevation: 0,
        backgroundColor: const Color.fromARGB(255, 10, 11, 102),
      ),
      drawer: const CustomDrawer(),
      body: Center(
        child: Text('Home'),
      ),
    );
  }
}

custom_drawer.dart

class CustomDrawer extends StatelessWidget {
  const CustomDrawer({Key? key}) : super(key: key);

  @override
  Widget build(BuildContext context) {
    Widget _drawerItems({String? text, IconData? icon, String? route}) {
      return ListTile(
        leading: icon == null ? null : Icon(icon),
        title: Text(text!),
        onTap: () {
          Navigator.of(context)
              .pushNamedAndRemoveUntil(route!, (route) => false);
        },
      );
    }

    return Drawer(
      child: Column(
        children: [
          // Drawer Header
          Container(
            height: 150,
            color: const Color.fromARGB(255, 10, 11, 102),
            child: const Center(
              child: Text(
                'Welcome',
                style: TextStyle(
                  color: Colors.white,
                ),
              ),
            ),
          ),
          Expanded(
            child: ListView(
              padding: EdgeInsets.zero,
              children: [
                // Home
                _drawerItems(
                  text: 'Home',
                  icon: Icons.home_outlined,
                  route: homeScreenRoute,
                ),
                ExpansionTile(
                  title: const Text('Products'),
                  leading: const Icon(Icons.production_quantity_limits),
                  children: [
                    // All Products
                    _drawerItems(
                      text: 'All Products',
                      route: productScreenRoute,
                    ),
                    // Add Products
                    _drawerItems(
                      text: 'Add Products',
                      route: addProductScreenRoute,
                    ),
                  ],
                ),
              ],
            ),
          ),
        ],
      ),
    );
  }
}

How can I fix this?

It also sometimes blinking when I am dragging it to left or right...

I'm using my phone (Redmi Note 7) to debug.

So, is this a problem with that?

Or am I using drawer widget in the wrong way?

CodePudding user response：

I've run your code and it works like a charm.

It works well on my phone too ( Redmi K30 4G ).

Here's what it looks like on my phone.

Also, your code is correct and I see nothing wrong with it. May be your phone has a problem.

Here's your output on emulator.

Can you release your app and test it on Redmi Note 7 to see if it's working?

For release mode, run flutter build apk and copy apk from $project_directory\build\app\outputs\app-release.apk.

Although it's working fine for me too, Just try adding this, maybe it can fix it!
