We will be updating the sdk with neww features real soon. Will keep everyone informed here.

Thank you, please provide well documentation.

Definitely. We also are very open to contributions of any form. So feel free to raise PRs.

Hi I can't found github growthbook flutter repository for version 3.7.0. You all migrate the repository? I need some help, I can't import GBExperimentResult when use 3.7.0. Then, I found an issue when launch on Flutter Web, I want to fix this issue. But, for now I can't contribute to your repository. I see latest master commit is 8 month ago on https://github.com/alippo-com/GrowthBook-SDK-Flutter thanks. cc: @gifted-cat-24658 @glamorous-florist-39551 @fresh-football-47124

Hi @calm-dog-24239 I create a pull request, please to review my changes maybe you have any concern. If Growthbook team approved for my changes, I will merge the PR. Thanks. https://github.com/growthbook/growthbook-flutter/pull/13 cc: @fresh-football-47124

Hi @calm-dog-24239 I have new pull request on your plugin, I got an issue when running Growthbook Flutter SDK on Flutter Web because in that platform we can't use

dart:io

. So, I try with another approach like shared preferences instead of file.

Hello, I am facing issue to fetch the feature flag in flutter app. Do anyone know how can I get the feature flag? I attached the SS of my GB feature which i am reading in the app using GB SDK.

Help on feature flag. 🚨 I’ve implemented

feature flag

in flutter and reading the feature but it is not picking the value from

Percentage Rollout

instead it is showing me the default value of GB. Do anyone know or faced similar issue before? I am using

growthbook_sdk_flutter: ^3.9.4

. here is the code I shared above. https://growthbookusers.slack.com/archives/C038XP683NC/p1720552142529219 @most-spoon-61816 @brief-honey-45610

I am looking for guidance in terms of what the best approach is for implementing unit tests with the latest SDKs. In general it seems there needs to be support for the following. • a flag or something to enable a local mode during initialization (where it doesn't go out over the network) • a way to explicitly override a specific feature flag with a unit test (used during the setting up initial state portion of the test) • a way to clear all feature flag overrides (used in a hook before each test case to make sure we don't have state bleeding across tests) I am particularly interested in the Javascript, Ruby, and Flutter SDKs. Reading through the Flutter docs, https://docs.growthbook.io/lib/flutter and https://github.com/growthbook/growthbook-flutter, it isn't clear how we should be writing our unit tests when a feature flag is in play either. Again please provide any guidance.

Hey All, I am new to Growthbook so this could be a simple change / fix. All works for all our sites but we now have one flutter app and our dev team has implemented the flutter code ( I am seeing a connected line from the flutter app to Growthbook within the SDK connection ) So my next step is going to setup an experiment but I am still not able to click on elements and change text in the Visual Editor is this a flutter issue / implementation issue / user issue or something else. Is there anyone that can help me setup an experiment?

I'm having issues writing an experiment for a flutter app. I am just wanting to break it down to an easy change such as a text change but can't find much documentation or starting points to get me going. I did try and get chatGPT to help me write something but I never got anything working. Is there some example experiments somewhere I couldn't see anything in the docs but hoping I missed it.

Hello! I implemented the SDK without issues, feature flags are working properly, they update once it is changed in the dashboard, so all good there. The problem I am having is with the AB experiments, they simply are not showing up. I tested and debugged with 3 different feature flags, the experiments field/attribute in the feature flags never comes with data. Any ideas on what could be happening?

Hello! Is there a way to retrieve features specific to the current project? For example, I have two projects under the same GrowthBook account, and they use different tags and different project name. Is it possible to initialize the GrowthBook SDK in a way that only loads features related to a specific app (maybe by tag or project name)? Can't find it in docs. Thank you!

Hi Team, our organisation is using Growthbook with streamline features, but we are facing starting trouble, If we pass backgroundSync: true, it takes lot of time to load the page and screen goes blank, I have to pass it as false first and later we have to pass it as true then only it works. This is my code snnippet, can someone help me to resolve this. gb = await GBSDKBuilderApp( hostURL: "", apiKey: "", growthBookTrackingCallBack: (exp, rst) {}, backgroundSync: true, ).setRefreshHandler((updated) { if (updated) { _fetchFeatureData(); } }).initialize(); await gb?.refresh().whenComplete(() => print(gb?.features().keys)); }

@calm-dog-24239, streaming with latestest version is working perfectly fine now, Thank you so much 🙌.

Hi, I need help. The problem is that in this example growthBookTrackingCallBack is never called. For debug purpose I tried to call growthbook.run() explicitly - then growthBookTrackingCallBack is called. Experiment setup is to use 100% of traffic with no filtering. Environment and project is the same for test, sdk and feature.

Hey! I just noticed a small typo in docs for flutter sdk. backroundSync -> backgroundSync

Hey team, 👋 I’ve encountered an issue with the GrowthBook SDK where calling the refresh() method temporarily resets feature values to their initial state. This results in incorrect or empty values during the refresh process. You can find the details and test the issue here: 👉 GitHub Issue - GrowthBook SDK Refresh Bug Please take a look when you can!

Hey team! I'm seeing an issue with a gated feature flag for certain mobileAppVersions still showing up for improper versions. Can someone help us triage the issue?

Hey folks, I'm trying to figure out how real-time feature updates are working? how can I subscribe to the stream or listen to the feature changes?

Hi Team, a customer is using version 3.9.10 and they're having an issue with remote evaluation using the GrowthBook SDK and are receiving all features with their default values. They noticed that this is being caused as evaluationContext is null aswell as the user attributes too. They are setting the user attributes during initialization in the correct syntax They have noticed that the initialize() method in the GrowthBook SDK doesn’t allow them to pass an evaluationContext. How should they handle evaluationContext for remote eval? It seems that remote eval doesnt get attributes parsed to the SDK. Should they be using secure attributes instead?

Hi Team, I want to ask about percentage rollout logic from Growthbook. Assume currently I have split between control and variant with same value 50%. Then, my team want to update the variant from 50% to 70% and control from 50% to 30%. Users that existing get control will be changed into variant and vice versa? Or, just changed from control to variant only? Without any changes from existing variant?

Hey folks. Please, update docs for remote-evaluation

Hey folks, I just opened an issue related to remoteEval in the Flutter SDK: https://github.com/growthbook/growthbook-flutter/issues/111 Would be great if you could take a look when you have a moment. It’s about a potential race condition during initialize() that leads to null or stale feature values on app startup. Thanks a lot!

Hey folks 👋 Just noticed that the 4.0.0 release in the Flutter SDK changelog is listed below some earlier versions like 3.1.0 and 3.2.0. That might make it easy to miss — especially since it includes breaking changes. Might be worth moving it to the top so devs spot it right away when checking for updates.

One more question. We were previously using version 3.9.9, but recently updated to the latest SDK to take advantage of remote evaluation. Just to confirm our understanding: Before (in 3.9.10 and earlier), calling sdk.feature('test-flag').on didn’t trigger a request to fetch feature flags from the server — it only relied on locally cached or preloaded data, correct? But from what we see, that behavior changed in version 3.9.11 (commit link); now the SDK uses caching (with a default TTL of 60 seconds), and if the cache is expired, it fetches fresh data from the server. Is that correct?

Hey, I’m here again 😄 Sorry, but my current task is closely related to the GrowthBook SDK. I ran into an issue where sdk.feature().value returns null on the second call after updating to 4.0.0. I opened an issue with a reproducible example: https://github.com/growthbook/growthbook-flutter/issues/114 Take a look when you have a moment. Let me know if I’m missing something.

Hi Team, a large Enterprise customer is facing an issue with the refreshHandler only triggered during initialization. They are using 3.9.14 and looking at thread here another customer faced the same. Please can you review this?
