otel_redux 0.2.0

OpenTelemetry instrumentation for `package:redux`. Provides a Middleware that emits a span per dispatched action.

otel_redux

OpenTelemetry instrumentation for package:redux. Plug a middleware into your store and every dispatch shows up in your trace.

import 'package:redux/redux.dart';
import 'package:otel_redux/otel_redux.dart';

final store = Store<AppState>(
  appReducer,
  initialState: AppState.initial(),
  middleware: [otelReduxMiddleware<AppState>()],
);

store.dispatch(AddToCartAction(item: item));
// → span: `redux AddToCartAction`

Each dispatch opens an INTERNAL span with:

• name: redux <action runtime type>
• state.system = redux
• state.operation = dispatch
• state.action.name = <runtime type>

Spans inherit the surrounding active span as parent, so a dispatch inside a Tracer.startActiveSpan('user_flow', ...) nests naturally.

Suppression: runWithoutReduxInstrumentation and async variant.
