kaisel

Implement and reason about Flutter routing using the kaisel library — a Dart 3-native router built on sealed routes, pattern matching, and a stack-as-state model. Use this skill when the user is using or considering kaisel, migrating to it from go_router, auto_route, or Flutter's Navigator (named, imperative, or 2.0), or when their code shows kaisel imports.
