otel_auto_route 0.1.0

OpenTelemetry instrumentation for `package:auto_route`. An AutoRouterObserver that emits a span per stack transition AND per tab transition - tabbed apps do not lose views.

Changelog

0.1.0 - 2026-08-08

Added

• OTelAutoRouterObserver — a real AutoRouterObserver subclass (previously a typedef alias for a plain NavigatorObserver). The subclass receives auto_route's didInitTabRoute / didChangeTabRoute callbacks and emits route.tab_init:<path> / route.tab_change:<path> spans with navigation.action and navigation.route.path (+ navigation.previous_route_path) — tab switches in AutoTabsRouter apps are no longer silently lost views. Stack transitions (push / pop / replace / remove) emit route.<transition>:<path> spans of the same shape.
• AutoRouteSemantics — typed navigation.* attribute keys, pinned by a wire-format test. Key strings are wire-identical to the sibling otel_go_router integration, so a mixed go_router + auto_route codebase produces one uniform trace vocabulary.

Changed

• Decoupled from otel_go_router: the dependency (and its path dependency_override + publish-order chain) is gone — competing routers must not be coupled, and auto_route users no longer transitively install go_router. The shared route semantics are inlined as AutoRouteSemantics; the wire contract is the key strings, pinned by test, not a shared symbol.
• Raised SDK floor to dartastic_opentelemetry ^1.1.0-beta.12.
• Widened auto_route to >=9.0.0 <12.0.0 (analyze + tests green against both 9.0.0 and 11.1.0).
