  ProductInfoResult res = await IapClient.obtainProductInfo(req);
  return res.productInfoList; // A value of type 'List<ProductInfo>?' can't be returned from the method 'getConsumableProducts' because it has a return type of 'Future<List<ProductInfo>>'

If you want to obtain purchase information, you could follow the code below:

List<String> productIdList = new ArrayList<>();
// Only those products already configured in AppGallery Connect can be queried.
productIdList.add("ConsumeProduct1001");
ProductInfoReq req = new ProductInfoReq();
// priceType: 0: consumable; 1: non-consumable; 2: subscription
req.setPriceType(0);
req.setProductIds(productIdList);
// Obtain the Activity object that calls the API.
final Activity activity = getActivity();
// Call the obtainProductInfo API to obtain the details of the product configured in AppGallery Connect.
Task<ProductInfoResult> task = Iap.getIapClient(activity).obtainProductInfo(req);
