Drawer Widget in Flutter

You may make your application’s many destinations and features more accessible with a drawer widget. The three parallel horizontal lines at the top of the scaffolding stand for it. The link to various routes in the Flutter app can be accessed horizontally from the Scaffold’s edge. The app drawer requires the material component package, which may be imported with the command in flutter package.

The header, body, and footer are the three main parts of the navigating app drawer. The basic concept is to have a navigator who, when tapped, will take a couple of objects from a drawer and send them to different locations. Typically, all of a Drawer widget’s children are displayed in ListView. At first, the user interface just shows the DrawerHeader, which expands horizontally when touched.

Why Drawer Widget?

Drawer Widget make it easy to balance different functions of your mobile app simultaneously and are very simple to add. Adding a drawer to your app makes going to different places in it much easier and more doable, especially if your app is complicated and has a lot of screens.

You can do things and switch between screens without much trouble.

How to Make a Drawer: There are only four easy steps to setting up a drawer:

Make a project with Flutter: Just launch and go to where you’d like to start working on your project. You can create a new Flutter project by using the “flutter create project_name” command.

Design a scaffolding widget: Put a scaffold widget back into your stateless or stateful widget’s MyApp class. The fundamental visual layout structure of a Flutter app can be implemented with the help of a Scaffold Widget.

Place a drawer within the scaffolding: You have two options: either add a Container with a ListView as a child or set the scaffold’s drawer attribute to Drawer with ListView as its child. Several ListViews hold the items that should be shown in the drawer.

Framework Drawer Widget

When a user wants to close a drawer after tapping on an item, the navigator is utilized to provide the closing behavior. A Navigator State can accomplish this flutter.  

Properties

child: The widgets in the tree below this one.

Hashcode: This is the object’s hash code.

Key: Sets how one widget can take the place of another in the tree.

runtimeType: The runtime type of the object is shown here.

Elevation: Where in the parent tree this box should be placed based on its z-coordinate.

semanticLabel: The dialogue’s semantic name is used by accessibility frameworks to let users know when the screen changes when the drawer opens and closes. 

Different kinds of navigation drawers: There are three types of apps in an app Drawer Widget:

Drawer for standard navigation: They let the user interact with both the information on the screen and the drawer at the same time.

Drawer for Modal Navigation: These drawers make it so that the user can only deal with the drawer and not the rest of the screen.

Drawer for bottom navigation: They work like modal navigation drawers, but the drawer faces the bottom of the screen instead of vertically.
