setAllowSharingStoreAccount static method
Set this to true if you are passing in an appUserID but it is anonymous.
This is true by default if you didn't pass an appUserID. If a user tries to purchase a product that is active on the current app store account, we will treat it as a restore and alias the new ID with the previous id.
Implementation
static Future<void> setAllowSharingStoreAccount(bool allowSharing) {
return rc.Purchases.setAllowSharingStoreAccount(allowSharing);
}
