Describe the bug
calling purchasePackage() would throw this error after subscription purchase is complete

_InternalLinkedHashMap<Object?, Object?>' is not a subtype of type 'Map<String, dynamic>

1. Environment

   1. Output of flutter doctor [✓] Flutter (Channel stable, 2.8.0, on macOS 11.5.2 20G95 darwin-x64, locale en-ET) [✓] Android toolchain - develop for Android devices (Android SDK version 31.0.0) [!] Xcode - develop for iOS and macOS (Xcode 12.5.1) ! Flutter recommends a minimum Xcode version of 13.0.0. Download the latest version or update via the Mac App Store. [✓] Chrome - develop for the web [✓] Android Studio (version 2020.3) [✓] VS Code (version 1.63.2) [✓] Connected device (2 available)
   2. How widespread is the issue. Percentage of devices affected

   I only tested on Android.

2. Debug logs that reproduce the issue

Issue is not caught by package but error thrown is type '_InternalLinkedHashMap<Object?, Object?>' is not a subtype of type 'Map<String, dynamic>'

3. Steps to reproduce, with a description of expected vs. actual behavior
   call purchasePackage method with subscription packages should reproduce the error
   PurchaserInfo purchaserInfo = await Purchases.purchasePackage( offering.availablePackages.first, );

4. Other information (e.g. stacktraces, related issues, suggestions how to fix, links for us to have context, eg. stackoverflow, etc.)

final prorationMode = upgradeInfo?.prorationMode; final response = await _channel.invokeMethod('purchasePackage', { 'packageIdentifier': packageToPurchase.identifier, 'offeringIdentifier': packageToPurchase.offeringIdentifier, 'oldSKU': upgradeInfo?.oldSKU, 'prorationMode': prorationMode?.index }); return PurchaserInfo.fromJson(response['purchaserInfo']);

return PurchaserInfo.fromJson(response['purchaserInfo']); seems to be where the error is happening

I have this problem too.
This is the complete exception log:
Unhandled Exception: type '_InternalLinkedHashMap<Object?, Object?>' is not a subtype of type 'Map<String, dynamic>' #0 Purchases.purchaseProduct (package:purchases_flutter/purchases_flutter.dart:199:43) <asynchronous suspension>
I get this error each time I make a purchase, in my case a renewable subscription.

Confirm on Android also.

STR

    try {
      final purchaserInfo = await Purchases.purchasePackage(package);
      ...
    } on PlatformException catch (ex) {
      // it's OK
    } catch (ex) {
      // have the error:
      //   type '_InternalLinkedHashMap<Object?, Object?>' is not a subtype of type 'Map<String, dynamic>'
    }

More tests to the god of tests, guys!

Looking into it

[vegaro]

Looks like response['purchaserInfo'] is not Map<String, dynamic> anymore and it's a Map<Object?, Object?> now. Trying to figure out why.

Looks like response['purchaserInfo'] is not Map<String, dynamic> anymore and it's a Map<Object?, Object?> now. Trying to figure out why.

is this happing because of a change in server response to purchasePackage() from revenue cat? it looks like it,

[vegaro]

No. I just checked and this is not happening in version 3.8.0. I've reverted every commit and I think I isolated it to be caused by #270. But I still don't understand how that PR can cause to change what purchasePackage is returning from the Native side.

Also, this is what response looks like:
