happy to help you debug if you share more of the code

10/13/2022, 4:18 AMI use Flutter SDK @fresh-football-47124
I was intance an Growthbook SDK via wrapper using this code
Copy code
GrowthBook(
apiHost: F.growthBookApiHost,
apiKey: growthBookApiKey,
isQAMode: (F.appFlavor == Flavor.staging),
trackingCallback: (experiment, result) {
// any tracker method
},
),Then in specific page, I was get assigned value using this code
Copy code
const id = 'pdp-palingmurah';
final feature = _growthBook.instance.feature(id);
if (feature.value == 'PDP-Title') {
_cheapestBadge.value = CheapestType.title;
} else if (feature.value == 'PDP-Price') {
_cheapestBadge.value = CheapestType.price;

Can you debug what the feature(id) is returning?
c
cool-apple-97384
10/13/2022, 4:23 AMYes @fresh-football-47124 I receive assigned value. In several account I use forced value. When I debug and trial the app. The value assigned based on forced value assigned.

okay, for forced values, that tracking callback wont be called
c
cool-apple-97384
10/13/2022, 4:24 AMI see. So, if I want to check the callback, I need to use an user that not registered in forced value?

10/13/2022, 4:44 AMHi @fresh-football-47124 I was test using another account but the value always assigned using default value. I try set default value with variation 1, user will received variation 1. Then, I change default value with variation 2, user will recieved variation 2. What should I do?

is the ID being set before the feature is evaluated?
c
cool-apple-97384
10/13/2022, 4:48 AMYes I was instance the GrowthBook first after main.dart called. Then id wil be set after login. So, before login, we set empty map.

I have a feeling that it’s not correctly updating the attributes so it’s serving the default value
Can you debug what the
