5. Scrollable Widgets

Written by Vincent Ngo

Building scrollable content is an essential part of UI development. There’s only so much information a user can process at a time, let alone fit on an entire screen in the palm of your hand!

In this chapter, you’ll learn everything you need to know about scrollable widgets. In particular, you’ll learn:

• How to use ListView.
• How to nest scroll views.

You’ll continue to build the Yummy app by adding HomeScreen, a new view that enables users to explore different restaurants, food categories, and view friends’ posts.

By the end of this chapter, you’ll be a scrollable widget wizard!

Getting Started

Open the starter project in Android Studio, then run flutter pub get if necessary and run the app.

You’ll see a placeholder for each tab as shown below:

Project Files

There are new files in this starter project to help you out. Before you learn how to create scrollable widgets, take a look at them.

Assets Folder

The assets directory contains all the images that you’ll use to build your app.

Sample Images

• categories: Contains images for food categories.
• food: Contains sample food items from a restaurant menu.
• profile_pics: Contains Kodeco team member pictures.
• restaurants: Contains restaurant hero images.

New Classes

In the lib directory, you’ll also notice the new api folder, as shown below:

API Folder

The api folder contains a mock service class.

Introducing ListView

ListView is a very popular Flutter component. It’s a linear scrollable widget that arranges its children linearly and supports horizontal and vertical scrolling.

Introducing Constructors

A ListView has four constructors:

Setting Up the Explore Screen

The first screen you’ll create is the ExploreScreen. It contains three sections:

Nested ListViews

There are two approaches to adding the category and post sections: the Column approach and the nested ListView approach. You’ll take a look at each of them now.

Column Approach

You could put the list views in a Column, that arranges items in a vertical layout. So that makes sense right?

Nested ListView Approach

In the second approach, you nest multiple list views in a parent list view.

Other Scrollable Widgets

There are many more scrollable widgets for various use cases. Here are some not covered in this chapter:

Key Points

• ListView and GridView support both horizontal and vertical scroll directions.
• The primary property lets Flutter know which scroll view is the primary scroll view.
• physics in a scroll view lets you change the user scroll interaction.
• Especially in a nested list view, remember to set shrinkWrap to true so you can give the scroll view a fixed height for all the items in the list.
• Use a FutureBuilder to wait for an asynchronous task to complete.
• You can nest scrollable widgets. For example, you can place a grid view within a list view. Unleash your wildest imagination!

Where to Go From Here?

At this point, you’ve learned how to create ListViews. They are much easier to use than iOS’s UITableView and Android’s RecyclerView, right? Building scrollable widgets is an important skill you should master!
