The drawer moves horizontally from the edge of the scaffold, allowing navigation to different routes in the Flutter app.

• hashCode: Indicates the hash code for this object.

• key: Manages how one widget replaces another widget in the tree.

• runtimeType: Shows a representation of the runtime type of the object.

    home: DrawerExample(),
