Using the VWO demo app, you can try Mobile App A/B testing.
To try the demo app, you will need ApiKey.

Installation

git clone https://github.com/wingify/vwo-flutter-sdk
cd vwo-flutter-sdk/example
flutter pub get

iOS/Android

flutter run

Enter ApiKey

You need to add an app to your VWO account. Please refer to Adding an App for details.
Copy your ApiKey.
Run the app from Android Studio/Xcode.

After the app is running, click the Menu icon in the upper-left corner.

Select Enter API Key from the menu options and then type your API key.

Sorting Campaign

Showing a list of items is a common requirement for many apps.
How do you know what sequence is better? What better way to tell than to A/B test!

Defining Variation

Steps to run Sorting Campaign:

1. Under Mobile App A/B, click Create Menu and then choose your App, platform and set test key to "sorting". Click Next for Variations screen.
2. On the Variations screen, update the variation names as seen in the image below

In your app, click the Refresh icon located in the upper-right corner of the navigation bar.
This should change the sequence of items. Items are now sorted by price

Following code handles the A/B testing for Sorting campaign

String variationName =
      await VWO.getVariationNameForTestKey(Constants.TEST_KEY_SORTING);
   if (variationName != null) {
     switch (variationName) {
       case Constants.TEST_KEY_VALUE_SORT_BY_NAME:
         mobileList.sort((a, b) => a.name.compareTo(b.name));
         break;
       case Constants.TEST_KEY_VALUE_SORT_BY_PRICE:
         mobileList.sort((a, b) => a.price.compareTo(b.price));
         break;
       default:
         mobileList.sort((a, b) => a.id.compareTo(b.id));
         break;
  }
}

The code above does following things

1. Get the variation name for campaign whose test key is "sorting"
2. Depending on the variation name we decide if the sorting is to be done alphabetically or by price
3. Once the list is sorted we reload the table data

Defining Goals

Click Next, and then define a goal using the following goal identifier.

We can see if the goals work correctly.
Click Verify.

Select your device from the drop-down menu.

On selecting any product (phone) from the list, you can see the product details.

When you select the product, Goal 1 becomes Verified.

This happens because, we have placed VWO.trackConversion( "productView") code upon selecting a product.

If you want to verify the goal for variation, select Variation from the drop-down menu, select refresh in the app, and then repeat the same process.

Finalize Campaign

Click Next to move to the final stage of campaign creation. You can set percentage traffic allocation and then do advance targeting.

To start the campaign, click Finish.
