add activity issue

[lonesomeranger]

Hi, I am doing the tutorial. I am new to flutter and aws. The tutorial is great and helps me to get into it better.

However I am stuck in tutorial two module 3.

Everything works good so far. But when opening add_activity_page.dart it is loading the activity for a few ms and then switching to CircularProgressIndicator().

It seems that the asyncvalue loses its object when the widget is build again:

tripValue.when(
    data: (trip) => SingleChildScrollView(...)
    loading: () => const Center(
          child: CircularProgressIndicator(),
    ),

Since the tripValue comes from tripProvider final tripValue = ref.read(tripProvider(tripId)); in trips_repository.dart as a ProviderStream and the get stream 'return tripsRepository.get(id);' comes from trips_datastore_service.dart and Stream<Trip> getTripStream(String id) and then from the Amplify.DataStore and everything is connected via riverpod I am completly lost how to debug everything. I do not understand why the tripValue appears for a few hundret ms and then disapears.

What is the best way to debug changes of an Stream that comes from Amplify.DataStore?
Why is this getTripStream() a stream at all? Wouldn't it be easier to just have a Future here?

Thanks

Hi @lonesomeranger is this on Android or iOS? Did you checked if you are getting the trip from datastore?

You might need to reset the simulator between the tutorial's sections to pick up the changes on the schema
