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.

Hi, @tall-glass-41437. Yes, we can provide that to you.

Great, where can I find this info?

Need to create a new feature in console. Select string value type if you want text.

Thanks so much for this. I will give it a go today.

You are welcome

Hey Maxim, Sorry to bother you with this but this I feel completely lost with this. I have set up the experiment and feature and when trying to add the code I get a heap of errors so I am guessing I have initialised something wrong. Can you see the issue here? I am mainly getting a lot of undefined issues.

You just need to use your api key and hostURl

Great I finally got this to work. I have some what of an understand what its doing so I want to move on to doing a visual on page change but I can't find any documentation on this. Can you help me change some text on the actual page.

Hi, @tall-glass-41437. Yes, please describe what you want exactly to change.

Hi I have created an experiment which just returns one of two string variations. I have tried to put something together with chatGPT

Future<void> initializeSDK() async {
  if (_isInitialized) return; // Avoid re-initializing if already done

  // Initialize GrowthBook SDK
  gb = await GBSDKBuilderApp(
    apiKey: 'sdk-xxx', // Replace with your actual API key  
    hostURL: '<https://cdn.growthbook.io/>', // Replace with your actual GrowthBook URL
    growthBookTrackingCallBack: (exp, rst) {
      // Handle callback if needed
    },
    gbFeatures: {
      'flutter-pet-test': GBFeature(defaultValue: 'pet'),
    },
  ).initialize();

  // After evaluation, set the blurb text and log the value
  final expressBlurb = gb?.evalFeature('flutter-pet-test');

  setState(() {
    // Use the actual value returned from the feature evaluation
    expessBlurbText = expressBlurb?.value ?? 'Default Blurb';

    // Log the value (this could be the 'control' or any variant you defined)
    print('Feature Evaluation Value: ${expressBlurb?.value}');

    _isInitialized = true; // Mark as initialized
  });
}

I had it working some what and returning the control but now I am just getting the default text from the feature I created to set it up. I have no real idea what I am doing so any help would be great.

Hi, @tall-glass-41437. Please check if you correctly set up the features with experiments, I tried to run with your key.
