Kaisel – Routes as Values. Dart 3 Native Router for Flutter

3 hours ago

Navigation is a switch over a sealed type; adding a route forces the compiler to find every place that must handle it, eliminating runtime 'unknown route' errors.
The navigation stack is a value represented as a list of route objects, allowing push, pop, and set operations that are testable and restorable.
A single NavigatorObserver sees all navigation events, including tab switches and adaptive in-place changes that produce no route events in other routers.
Zero code generation is required—no build_runner, no generated files, no magic strings; routes are plain Dart classes.

Design patterns are reusable solutions to common software design problems, not algorithms but structures for data flow.
The Observer Pattern allows an observable object to notify multiple observer objects when an event occurs.
Common uses include asynchronous events (e.g., network data receipt) and GUI event handling (e.g., button clicks).

Blick enables instant editing with no import or project setup dialogs, opening directly to a blank project with autosave.
Users can start exports and continue editing without interruptions; even fix mistakes mid-render without restarting.
Keyframing is done directly in the timeline, allowing live animation recording during playback.

Primate 0.40 introduces collocated route pages, allowing routes to render frontend files next to them using response.page.
Layouts can also be collocated, with layout components receiving props and children from the route.
Store enums (p.enum) are now integrated into stores, providing validated, typed enums that store as plain integers.

Functional programming in hica emphasizes composing functions rather than changing state, with everything as an expression.
Immutability is default using 'let'; mutation uses 'var' locally, promoting pure functions without side effects.
Functions are first-class values, supporting higher-order functions, closures, and combinators like map, filter, and fold.

Gamepad API requires user interaction (plugging in or pressing a button) before it works to prevent information leaks.
Browser support varies; Firefox, Chrome, Opera, Safari, and Edge support it, but IE does not; Edge has quirks.
Use navigator.getGamepads() to get an array of gamepad objects; the array may contain null entries for disconnected slots.
