Can you explain what a Deeplink is and how it works in mobile applications?

Deeplink (deep link) is a special link that opens a specific screen or content within a mobile application, rather than just launching the app or a web page.

How it works:

• The user clicks on the link (for example, in an email or on a website).
• If the app is installed, the deeplink opens the desired screen with the necessary parameters.
• If the app is not installed, it can be configured to redirect to the app installation page or to the web version.

In Flutter, packages like uni_links or firebase_dynamic_links are often used to handle incoming links and navigate the user within the app.

Example of using uni_links:

import 'package:uni_links/uni_links.dart';

// In initState or a similar method
void initUniLinks() async {
  try {
    Uri? initialLink = await getInitialUri();
    if (initialLink != null) {
      // Handle the link
      print('Link opened: $initialLink');
    }

    uriLinkStream.listen((Uri? uri) {
      if (uri != null) {
        // Handle deeplink during app operation
        print('Received link: $uri');
      }
    });
  } catch (e) {
    // Handle errors
  }
}
