Hey @Mo0Khaled ,

Can you please provide the complete Rudder-Flutter SDK initialisation snippet?

Hey @Mo0Khaled ,

Can you please provide the complete Rudder-Flutter SDK initialisation snippet?

@1abhishekpandey Sure thing HYG:

     final builder = RudderConfigBuilder();

     final rudderTokenKey = BuildConfig.of().rudderTokenKey;
     final rudderDataPlaneUrl = BuildConfig.of().rudderDataPlaneUrl;

     builder.withDataPlaneUrl(rudderDataPlaneUrl);
     rudderClient.initialize(
       rudderTokenKey,
       config: builder.build(),
       )

Just to clarify, by this:

as I understand it should be logged be default.

Where exactly are you referring to? Is it the IDE logcat or the RudderStack dashboard?

I mean the dashboard but as we talked about on the other issue, we use customer.io dashboard

Could you please check the RudderStack—Flutter source live events tab (https://app.rudderstack.com/) and see if any lifecycle events (e.g., Application Installed, Application Opened, or Application Backgrounded) are reported or not?

Tested it now and nothing there too.

Is there an extra code should be written to make this work?

The timer needs to be running. Just click on Resume and you'll observe all the events made by the Flutter source e.g., refer to this:

No additional code should be required to make the lifecycle events. They are enabled by default on the Android and iOS side. But if needed you can refer to our sample app:

MobileConfig mc = MobileConfig(
    recordScreenViews: true,
    collectDeviceId: false);

RudderConfigBuilder builder = RudderConfigBuilder();
builder
  ..withDataPlaneUrl(
      dotenv.env['DATA_PLANE_URL'] ?? "https://hosted.rudderlabs.com")
  ..withMobileConfig(mc)
  ..withLogLevel(RudderLogger.VERBOSE);
String writeKey = dotenv.env['WRITE_KEY'] ?? "INVALID_WRITE_KEY";
rudderClient.initialize(writeKey, config: builder.build(), options: null);

If it still doesn't work, please install the app fresh, run it for 30 seconds, move the app to the background and foreground, and share the complete Android logcat filtered by RudderSDK. We can then verify whether lifecycle events are made or not.

Hey @Mo0Khaled,

Could you please let us know if your issue has been resolved or if you need any further assistance?

[Mo0Khaled]

Hello @1abhishekpandey ,

still not working we have tried it on version 2.9.0 and it's working is this information helpful for you so you can help me find the issue?

[1abhishekpandey]

Could you please provide this and attempt to install the Flutter SDK in a new sample app?

If it still doesn't work, please install the app fresh, run it for 30 seconds, move the app to the background and foreground, and share the complete Android logcat filtered by RudderSDK. We can then verify whether lifecycle events are made or not.

By the way, there have been no changes to the lifecycle from v2.9.0 to the latest version.
