Kaisel Router for Flutter Offers Sealed Routes and List-Based Navigation
Key points
- Uses sealed types for routes, enabling compile-time checks.
- Navigation history is managed as a list of route objects.
- No code generation is required for route definitions.
- Supports a single NavigatorObserver for all navigation events.
Introduction of Kaisel Router
Kaisel is a new native router designed for Flutter applications, leveraging Dart 3 features. It focuses on providing a structured and type-safe approach to navigation within Flutter projects.
Sealed Routes and Compile-Time Safety
The router utilizes sealed types for defining routes, which allows the compiler to verify that all possible navigation paths are handled. This eliminates runtime errors related to unknown routes, as the compiler identifies unhandled cases during the build process.
List-Based Navigation Stack
Kaisel manages the navigation history as a standard Dart List of route objects. This design simplifies operations like pushing, popping, and setting routes, treating them as list manipulations. The list-based stack is testable without a widget tree and can be restored across process terminations.
Observer and Codegen-Free Operation
The router supports a single NavigatorObserver that tracks all navigation events, including tab switches and in-place adaptive changes. Kaisel operates without requiring code generation tools like build_runner, allowing routes to be defined using plain Dart classes.
