DeeplinkHandlerStrategy class abstract

Strategy for iterating through multiple deeplink handlers.

Determines the order in which handlers are called when processing a deeplink. Iteration stops at the first handler that returns a non-null result.

Two built-in strategies are provided:

• DeeplinkHandlerStrategy.fifo — handlers are called in registration order.
• DeeplinkHandlerStrategy.lifo — handlers are called in reverse order.

To implement a custom strategy, extend this class and override apply:

class MyCustomStrategy extends DeeplinkHandlerStrategy {
  const MyCustomStrategy();

  @override
  Iterable<DeeplinkHandler> apply(Iterable<DeeplinkHandler> handlers) {
    // Return handlers in the desired order.
    return handlers.where((h) => h is MyPriorityHandler).followedBy(
      handlers.where((h) => h is! MyPriorityHandler),
    );
  }
}
