Deep Linking in Flutter

Deep linking is one of those features that quietly powers growth. It lets users jump straight into a specific screen inside your app — whether that’s a product, chat, or offer — just by tapping a link.

In the Test App, we’ve implemented deep linking using app_links, enabling both Android App Links and iOS Universal Links for URLs like:

This article walks through how the setup works in production, from Flutter handling to platform-specific configurations.

Why Deep Linking Matters

Before diving into implementation, here’s why it’s worth doing properly:

• Better user experience (direct navigation)
• Higher conversion from marketing campaigns
• Seamless sharing between users
• Essential for payment redirects (e.g., after checkout)

How We Handle Deep Links in Flutter

The app uses the app_links package, which provides two core APIs:

• getInitialLink() → Handles cold start (app launched from a link)
• uriLinkStream → Handles links while app is running

Entry Point: Splash Screen

All deep link logic is initialized early in the app lifecycle.
