The steps in this technique are as follows:

  1. Create a Scaffold.
  2. Add a drawer.
  3. Populate the drawer with items.
  4. Close the drawer programmatically.

Step 01: Create a “Scaffold”.

Scaffold(
  drawer: // Add a Drawer here in the next step.
);

Step 02: Add a drawer .

Scaffold(
  drawer: Drawer(
    child: // Populate the Drawer in the next step.
  ),
);

Step 03: Populate the drawer with items.

Drawer(
  // Add a ListView to the drawer. This ensures the user can scroll
  // through the options in the drawer if there isn't enough vertical
  // space to fit everything.
  child: ListView(
    // Important: Remove any padding from the ListView.
    padding: EdgeInsets.zero,
    children: [
      const DrawerHeader(
        decoration: BoxDecoration(
          color: Colors.blue,
        ),
        child: Text('Drawer Header'),
      ),
      ListTile(
        title: const Text('Item 1'),
        onTap: () {
          // Update the state of the app.
          // ...
        },
      ),
      ListTile(
        title: const Text('Item 2'),
        onTap: () {
          // Update the state of the app.
          // ...
        },
      ),
    ],
  ),
);

Step 04: Close the drawer programmatically

ListTile(
  title: const Text('Item 1'),
  onTap: () {
    // Update the state of the app
    // ...
    // Then close the drawer
    Navigator.pop(context);
  },
),
