A unified library to register custom URL protocol handlers across supported platforms.

This library is designed for use within Flutter and primarily to serve on Desktop platforms that require extra programmatic registration of URL handlers.

In other words, this library is meant to provide protocol registration on the Windows and Linux (coming soon) platforms.

Use the following to register or unregister a URL handler protocol.

import 'package:url_protocol/url_protocol.dart';

void main() {
  // Register a new custom URL protocol handler. Opening test-url-protocol://test
  // will run the executable with the arguments: -url test-url-protocol://test
  registerProtocolHandler('test-url-protocol', arguments: ['-url', '%s']);

  // Unregister and remove custom URL protocol handler
  unregisterProtocolHandler('test-url-protocol');
}

Use this library with multi_instance_handler to manage forwarding of the opened URL to the active instance of your application on Desktop platforms.

• Instructions for Android, iOS, macOS
