  # The following line ensures that the Material Icons font is

  uses-material-design: true

  # To add assets to your application, add an assets section, like this:
  # assets:
  #   - images/a_dot_burr.jpeg
  #   - images/a_dot_ham.jpeg

  # An image asset can refer to one or more resolution-specific "variants", see
  # https://flutter.dev/assets-and-images/#resolution-aware.

  # For details regarding adding assets from package dependencies, see
  # https://flutter.dev/assets-and-images/#from-packages

  # To add custom fonts to your application, add a fonts section here,
  # in this "flutter" section. Each entry in this list should have a
  # "family" key with the font family name, and a "fonts" key with a
  # list giving the asset and other descriptors for the font. For
  # example:



  #
  # For details regarding fonts from package dependencies,
  # see https://flutter.dev/custom-fonts/#from-packages

Steps to reproduce

1. Create a subscription and create 4 base plan
2. write code to subscription
3. try to upgrade/change plan using ReplacementMode: chargeProratedPrice
   Code:

` final PurchaseDetails oldPurchaseDetails = purchasesOnline.firstWhere(
    (element) =>
        element.status == PurchaseStatus.purchased ||
        element.status == PurchaseStatus.restored,
  );
  //recordAnalyticsChangeSub(oldPurchaseDetails, product);
  if (oldPurchaseDetails is GooglePlayPurchaseDetails) {
    // For android we need to manually upgade/downgrade subscription
    PurchaseParam purchaseParam = GooglePlayPurchaseParam(
      productDetails: product,
      changeSubscriptionParam: ChangeSubscriptionParam(
        oldPurchaseDetails: oldPurchaseDetails,
        replacementMode: ReplacementMode.chargeProratedPrice, //only chargeFullPrice works
      ),
    );

    await InAppPurchase.instance
        .buyNonConsumable(purchaseParam: purchaseParam);

    changingPlan = false;
`

Expected results

Should show the dialog with prorated price and others info

Actual results

Please provide us complete runnable and reproducible code sample without third party package implementation, as I see from the pubspec.lock file you are using lot of external dependencies. Just try to trim down the code to in_app_purchase only to see if the reported behavior still occurs or not.

Getting this error:

Is this coming locally or from play store ? Looks like it could be due to usage of applicationUserName that you should check to see if you are using it correctly and implemented properly or not.

[niilx]

Will provide.
But can you tell me after changing a plan, why I need to restart the app to change plan again?
unless getting that error "Something went wrong on our end".
Is it something with caching data or bug or behaviour for test purchase?
(using test subscription on google play)

Could be with google play.

Thanks for your replies, but I solved the issue by myself.
