How to create FAQ page with ExpansionTile in Flutter

What is a FAQ page

A FAQ (Frequently Asked Questions) page in a mobile app is similar to a FAQ page on a website. It is a screen that lists and answers common questions about the app or a particular feature of the app.

FAQ pages in mobile apps are often accessed through a menu or settings screen and are typically organized into categories or sections to make it easier for users to find the information they need. Some mobile apps also include a search bar or a contact form to allow users to ask additional questions or get more personalized help.

Like FAQ pages on websites, FAQ pages in mobile apps are a useful resource for users, as they provide quick and easy access to information about the app. They can also save time for customer support teams by handling common questions and issues.

To create a FAQ page in a Flutter mobile app, you can use a combination of widgets such as ExpansionTile, ListView, and Card. For example:

What is the ExpansionTile in Flutter

The ExpansionTile widget is a Flutter widget that allows you to create a list item that expands to reveal additional content when tapped. It is often used to create accordion-style lists or to reveal more information about a particular item.

The ExpansionTile widget has a title property that allows you to specify the title of the tile, and a children property that allows you to specify a list of widgets that will be displayed when the tile is expanded.

Here is an example of how to use the ExpansionTile widget in Flutter:

ExpansionTile(
  title: Text('Expandable Tile'),
  children: <Widget>[
    ListTile(
      title: Text('Item 1'),
      onTap: () {
        // Do something when item 1 is tapped
      },
    ),
    ListTile(
      title: Text('Item 2'),
      onTap: () {
        // Do something when item 2 is tapped
      },
    ),
  ],
),

In this example, the ExpansionTile widget has a title of “Expandable Tile” and two children: “Item 1” and “Item 2”. When the user taps on the tile, it expands to reveal the children.

You can customize the appearance of the ExpansionTile widget by using the leading, trailing, and backgroundColor properties. For example:

ExpansionTile(
  leading: Icon(Icons.home),
  title: Text('Expandable Tile'),
  trailing: Icon(Icons.arrow_drop_down),
  backgroundColor: Colors.grey[200],
  children: <Widget>[
    ListTile(
      title: Text('Item 1'),
      onTap: () {
        // Do something when item 1 is tapped
      },
    ),
    ListTile(
      title: Text('Item 2'),
      onTap: () {
        // Do something when item 2 is tapped
      },
    ),
  ],
),

What information can be added to the FAQ page

An FAQ page generally contains a list of questions and answers related to a product, service, or topic. Some things that can be added to an FAQ page include:

1. General information about the product, service, or topic
2. A list of frequently asked questions and answers
3. Tips and best practices for using the product, service, or topic
4. Troubleshooting and problem-solving information
5. Information about account setup and management
6. Information about privacy and security
7. Information about subscriptions and billing
8. Compatibility and device support information
9. Information about updates and version history
10. Customer support and contact information

The specific content of an FAQ page will depend on the nature of the product, service, or topic, and the needs and interests of the audience. The goal of an FAQ page is to provide users with the information they need to understand and use the product, service, or topic effectively.

Create FAQ page with ExpansionTile in Flutter

Create a list of questions and answers

final questions = [
  {
    'question': 'What is Flutter?',
    'answer': 'Flutter is a mobile app development framework created by Google. It allows developers to build natively compiled applications for mobile, web, and desktop from a single codebase.'
  },
  {
    'question': 'What are the benefits of using Flutter?',
    'answer': 'There are several benefits of using Flutter, including: fast development, expressive and flexible UI, hot reload, and good performance.'
  },
  {
    'question': 'Is Flutter only for mobile app development?',
    'answer': 'No, Flutter can be used to develop applications for mobile, web, and desktop. It supports building for Android, iOS, web, and desktop platforms.'
  },
  {
    'question': 'Is Flutter only for Android and iOS?',
    'answer': 'No, Flutter can be used to build applications for Android, iOS, web, and desktop. It has good support for all these platforms.'
  },
  {
    'question': 'Is Flutter only for small apps?',
    'answer': 'No, Flutter can be used to build small as well as large and complex apps. It has the capabilities and performance to handle any size of app.'
  },
];

This creates a list of dictionaries, each containing a ‘question’ and an ‘answer’ string. These strings will be used to populate the ExpansionTile widgets.

Create a widget that displays the FAQ page. You can use a ListView widget to display the list of ExpansionTile widgets:

body: Padding(
  padding: const EdgeInsets.all(8.0),
  child: ListView.builder(
    itemCount: questions.length,
    itemBuilder: (context, index) {
      final question = questions[index]['question'];
      final answer = questions[index]['answer'];
      return ExpansionTile(
        title: Text(question!),
        children: [
          Padding(
            padding: const EdgeInsets.all(8.0),
            child: Text(answer!),
          ),
        ],
      );
    },
  )
),

The body property contains a ListView widget, which displays a scrolling list of ExpansionTile widgets.

The ListView.builder method creates the ExpansionTile widgets dynamically, based on the number of items in the questions list. For each item in the list, it creates an ExpansionTile widget with the ‘question’ as the title and the ‘answer’ as the expanded content.

create a FAQ page in flutter, add the section with general information, Troubleshooting and problem-solving information, and Customer support and contact information

More details on the FAQ page

Here’s an example of how you might structure the FAQ page:

1. General information: This section could include a brief overview of the product or service, as well as any relevant background or context. You could use a ListView widget to display a list of questions and answers, or you could use a Card widget to display each question and answer as a separate card.
2. Troubleshooting and problem-solving information: This section could include information on common issues that users may encounter, and steps they can take to troubleshoot and resolve those issues. You could use a ListView or Card widget as in the previous section, or you could use a ExpansionTile widget to allow users to expand each question to see the answer.
3. Customer support and contact information: This section could include information on how users can get in touch with customer support, such as phone numbers, email addresses, and social media accounts. You could use a ListTile widget to display this information in a simple list, or you could use a Card widget to display the information in a more visually appealing way.

Here’s an example of how you might implement these sections using Flutter widgets:

ListView(
    children: [
      // General information section
      const ExpansionTile(
      title: Text('General information'),
      children: [
        ListTile(
          title: Text('What is this product/service?'),
          subtitle: Text('This is a product/service that does X, Y, and Z.'),
        ),
        ListTile(
          title: Text('How does it work?'),
          subtitle: Text('It works by doing A, B, and C.'),
        ),
      ],
    ),
    // Troubleshooting and problem-solving section
    const ExpansionTile(
      title: Text('Troubleshooting and problem-solving'),
      children: [
        ListTile(
          title: Text('I am having trouble logging in.'),
          subtitle: Text('Try resetting your password or contacting customer support for assistance.'),
        ),
        ListTile(
          title: Text('The app is crashing.'),
          subtitle: Text('Try closing and reopening the app, or contacting customer support for assistance.'),
        ),
      ],
    ),
    // Customer support and contact information section
    Card(
      child: Column(
          children: const [
        ListTile(
        title: Text('Customer support and contact information'),
        subtitle: Text('For assistance, you can contact us at the following numbers and email addresses:'),
      ),
        ListTile(
          leading: Icon(Icons.phone),
          title: Text('Phone number 1'),
        ),
        ListTile(
          leading: Icon(Icons.phone),
          title: Text('Phone number 2'),
        ),
        ListTile(
          leading: Icon(Icons.email),
          title: Text('Email address 1'),
        ),
        ListTile(
          leading: Icon(Icons.email),
          title: Text('Email address 2'),
        ),
        ],
      ),
    ),
    ],
)

This code creates a ListView as a body. The ListView has three children: an ExpansionTile for the general information section, an ExpansionTile for the troubleshooting and problem-solving section, and a Card for the customer support and contact information section.

The ExpansionTile widgets allow users to expand each section to see the questions and answers, while the Card widget provides a visually appealing way to display the customer support and contact information.
