@CloudyPadmal Looks nice, isn't it ?

There are few places with repetitive code.

Try,

final List<Map<String, dynamic>> contactItems = [
  {'icon': const Icon(Icons.mail), 'title': connectWithUs[1], 'url': 'mailto:$mail'},
  {'icon': const Icon(Icons.link), 'title': connectWithUs[2], 'url': website},
  {'icon': const Icon(FontAwesomeIcons.github, size: 20), 'title': connectWithUs[3], 'url': github},
  {'icon': const Icon(Icons.facebook_sharp), 'title': connectWithUs[4], 'url': facebook},
  {'icon': const Icon(FontAwesomeIcons.xTwitter, size: 20), 'title': connectWithUs[5], 'url': x},
  {'icon': const Icon(FontAwesomeIcons.youtube, size: 20), 'title': connectWithUs[6], 'url': youtube},
  {'icon': const Icon(Icons.person), 'title': connectWithUs[7], 'url': developers},
];

Create a widget

Widget buildContactList(List<Map<String, dynamic>> items) {
  return ListView.separated(
    physics: const NeverScrollableScrollPhysics(),
    shrinkWrap: true,
    itemCount: items.length,
    separatorBuilder: (_, __) => const Divider(thickness: 0.5, height: 1),
    itemBuilder: (context, index) {
      final item = items[index];
      return ListTile(
        leading: item['icon'] as Icon,
        title: Text(
          item['title'],
          style: const TextStyle(fontSize: 14),
        ),
        onTap: () async {
          final uri = Uri.parse(item['url']);
          if (await canLaunchUrl(uri)) {
            await launchUrl(uri);
          } else {
            debugPrint('Could not launch ${item['url']}');
          }
        },
      );
    },
  );
}

Use buildContactList(contactItems) in the Scaffold.

@CloudyPadmal Thank you very much for your comments. I’ve done the required changes and improved the layout a bit more.

[CloudyPadmal]

We can create this widget in the about_us_screen.dart as we are not going to reuse this anywhere else.

[Vidhijain20]

@CloudyPadmal Sure, I’ll move the widget to the screen itself.

[Vidhijain20]

@CloudyPadmal Done.

[CloudyPadmal]

Well done!
