otel_mobx

OpenTelemetry instrumentation for package:mobx.

import 'package:otel_mobx/otel_mobx.dart';

tracedRunInAction('add_to_cart', () {
  cart.add(item);
  total.value += item.price;
});

await tracedRunInActionAsync('checkout', () async {
  cart.clear();
  user.lastPurchase = DateTime.now();
});

Each call opens an INTERNAL span named mobx action <name> with state.system=mobx, state.operation=action, state.action.name=<name>. The span captures wall time for the action body — including any synchronous reactions it triggered.

Suppression: runWithoutMobxInstrumentation and its async variant.
