agent_gate_go_router 0.1.0

GoRouter adapter for agent_gate — AI-agnostic behavioural routing middleware for Flutter. Adds GoRouterAdapter and a GateRoute helper.

agent_gate_go_router

GoRouter integration for agent_gate — the AI-agnostic behavioural routing middleware for Flutter.

The core package already works with GoRouter through RouteNameAdapter; this package removes the boilerplate and adds the two things only a GoRouter-aware package can offer: a redirect middleware and a typed extra payload.

dependencies:
  agent_gate: ^0.1.0
  agent_gate_go_router: ^0.1.0
  go_router: ^17.0.0

Three integration styles

1. Imperative — GoRouterAdapter

final router = GoRouter(routes: [...]);

AgentGate.configure(
  decider: HttpDecider(endpoint: Uri.parse('https://api.example.com/gate')),
  adapter: GoRouterAdapter(router: router),          // or const GoRouterAdapter() to use GoRouter.of(context)
);

// Anywhere — no BuildContext needed when the router was passed explicitly:
await AgentGate.instance.navigate(checkoutGate);

Options: mode (go · push · pushReplacement · replace), useNamedRoutes, extraBuilder. Candidates need a route (path or name).

The destination receives a GateExtra so it can show why it was chosen:

GoRoute(path: '/checkout/assisted', builder: (context, state) {
  final why = state.gateDecision?.reason;      // extension on GoRouterState
  return AssistedCheckoutPage(banner: why);
});

2. Declarative page — GateRoute.page

The route is the gate; the AI-chosen candidate renders inline (candidates need builders):

GateRoute.page(
  path: '/checkout',
  gate: checkoutGate,
  contextFromState: (s) => {'coupon': s.uri.queryParameters['coupon']},
),

3. Redirect middleware — GateRoute.redirect / gateRedirect

Deep links resolve intelligently; nothing is built at the gate path:

GateRoute.redirect(path: '/checkout', gate: checkoutGate),
GoRoute(path: '/checkout/express',  builder: ...),
GoRoute(path: '/checkout/standard', builder: ...),
GoRoute(path: '/checkout/assisted', builder: ...),

or attach to any existing route: GoRoute(path: '/checkout', redirect: gateRedirect(checkoutGate), ...).

GoRouter shows nothing while a redirect is pending, so pair this with a short GateConfig.timeout or AgentGate.prefetch(gate) earlier in the flow. The redirect is loop-safe and always resolves (fallback on any failure).

Tracking pages with GoRouter

Add the core observer so enterPage / exitPage happen automatically:

GoRouter(observers: [GateNavigatorObserver()], routes: [...])
