Overview
The protocol_handler package enables Flutter applications to register and respond to custom URL schemes, facilitating deep linking across platforms. It allows apps to handle external links (e.g., myapp://open) by launching the app and passing data through the URI. This is particularly useful for integrating with other apps, web services, or system-level triggers. The plugin supports Android, iOS, macOS, and Windows, making it ideal for cross-platform desktop and mobile apps that require seamless navigation from external sources.
