Application Real-Time Monitoring Service:FAQ about Flutter app integration

My app calls WidgetsFlutterBinding.ensureInitialized before runApp. How do I handle this with the RUM SDK?

Use the beforeRunApp callback in AlibabaCloudRUM().start(). This callback runs before runApp, so Flutter binding initialization completes before the app starts.

AlibabaCloudRUM().start(
    MyApp(),
    beforeRunApp: () async =>
        {
          // Manually call the WidgetsFlutterBinding.ensureInitialized() method.
          WidgetsFlutterBinding.ensureInitialized(),
          await Dio().request("https://xxxxx.yyy/zzz")
        },
);

In this example, WidgetsFlutterBinding.ensureInitialized() and an asynchronous HTTP request both run inside beforeRunApp before the app launches.
