Deep Linking & URL Navigation

Deep linking lets an external source — an email, a notification, or a browser URL — open a specific screen inside your app instead of the home page.

• Improves user experience for shared content
• Essential for marketing campaigns and notifications
• On Flutter web, it ties your app to the browser URL bar

You will use a URL-based router to make this work cleanly.

There are two common forms:

• Custom scheme links like myapp://product/42
• Universal / App Links using real https:// URLs

Universal links are preferred because they fall back to a website if the app is not installed.
