android: fetchProducts() never returns on error

[Rockvole]

My code works :

IAPResponse response = await FlutterIap.fetchProducts(productIds);

Except in the case where there is a problem during the request (for example when trying the code on an emulator and there is no IAP). In this case we get the error text :

D/BillingManager( 3081): Destroying the manager.
D/BillingManager( 3081): Creating Billing client.
D/BillingManager( 3081): Starting setup.
D/BillingManager( 3081): Setup finished. Response code: 3

But the IAPResponse is never returned so my code is left hanging. It would be better if it returned with the status code so that I can do :

IAPResponse response = await FlutterIap.fetchProducts(productIds);
if(response.status==3) return false;

Thanks. I'll add that sometime soon.

Perhaps just return a empty product list?

It should also say why the list is empty if there is an error

@JackAppDev currently trying to get all error codes merged from iOS & Android into this master enum:

// Defines the response status for a IAP operation.
enum IAPResponseStatus {
    // All went well, see the other fields for response details.
    ok = 0;

    // Fatal error during the API action.
    error = 1;

    // (iOS only) Library user needs to fetch the list of products from the store first.
    emptyProductList = 2;

    // In-App purchases not available (device or policy constraints etc).
    disabled = 3;

    /// User pressed back or canceled a dialog
    userCanceled = 4;

    /// Network connection is down
    serviceUnavailable = 5;

    /// Billing API version is not supported for the type requested
    billingUnavailable = 6;

    /// Requested product is not available for purchase
    itemUnavailable = 7;

    /// Invalid arguments provided to the API. This error can also indicate that the application was
    /// not correctly signed or properly set up for In-app Billing in Google Play, or does not have
    /// the necessary permissions in its manifest
    developerError = 8;

    /// Failure to purchase since item is already owned
    itemAlreadyOwned = 9;

    /// Failure to consume since item is not owned
    itemNotOwned = 10;
}

If you spot any obvious error / missing code, please let me know. .disabled and .billingUnavailable can probably merge. disabled comes from the iOS part.
