Working with Drawers in Flutter: Tips & Tricks for Customizing Your App’s UI

Working with Drawers in Flutter

Drawers allow users to access app functions quickly without having to navigate through multiple screens. To create a Drawer in Flutter, the first step is to create a DrawerController. This will be the object responsible for handling the Drawer’s actions, such as opening and closing, and managing its content.

Once the controller is created, you can create a Drawer widget. This widget takes in a controller. You can also specify the width, height, and styles for your Drawer. Here is a basic example of a Drawer:

 DrawerController controller = DrawerController(); 
 
Drawer(
  controller:controller,
  width:300,
  height:500,
  style:TextStyle(fontSize: 18)
)

Now that you have the Drawer widget created, you can use it to display content. To do this, you need to create items that go in the Drawer. These items are usually subclasses of DrawerItem. Some common examples of DrawerItems include ListTile and ExpansionTile. Here is an example of how to create a ListTile:

ListTile(
  leading:Icon(Icons.home),
  title:Text("Home"),
  onTap:() {
    //some action here
  }
)

You can also use the ListView widget to display multiple DrawerItems inside the Drawer. Here is an example:

 Drawer(
  controller:controller,
  child:ListView( 
    children:[
     ListTile(
      leading:Icon(Icons.home),
      title:Text("Home"),
      onTap:() {
       //some action here
      }
    ),
    ListTile(
      leading:Icon(Icons.settings),
      title:Text("Settings"),
      onTap:() {
       //some action here
      }
    )
   ]
  )
)

The last step is to configure the DrawerController. You can set the initial state of the DrawerController by calling setVisibility(). You can also provide a callback function to trigger when the Drawer visibility changes. Here is an example:

 controller.setVisibility(
  initialVisibility:true,
  onVisibilityChange:(boolean visible){
   //Do something here 
  }
)

Once you have everything setup, you can start using the Drawer to provide quick access to different functionalities in your app. It is a great tool for providing a better user experience in your apps.
