Array of number not loading to List<double> in MAUI

Hi Tobias,

As background: I am in the process of porting from Xamarin to Maui and running into an issue where my firebase doc contains an array of numbers.

In Xamarin Forms I used https://github.com/f-miyu/Plugin.CloudFirestore which worked 100%. My web app uses the firebase npm module.

In the web app, the array is declared as: ele: number[] , and in Maui, its declared as:

[FirestoreProperty("ele")]
   public List<double> ele { get; set; }.

This worked 100% of Xamarin.Forms, but for some documents, when I try and retrieve the data (MyObject r = documentChange.DocumentSnapshot.Data; where ele is declared as a public property), the following execution is thrown:

The value "85" is not of type "System.Double" and cannot be used in this generic collection. (Parameter 'value')

The value of 85 varies based on the document. This is an array of elevations, and I have checked that the firestore document stores it as a number.

The full stack of the error is:

 at System.Collections.Generic.List`1[[System.Double, System.Private.CoreLib, Version=8.0.0.0, Culture=neutral, PublicKeyToken=7cec85d7bea7798e]].System.Collections.IList.Add(Object item)
   at Plugin.Firebase.Firestore.Platforms.Android.Extensions.ListExtensions.ToList(JavaList this, Type targetType)
   at Plugin.Firebase.Firestore.Platforms.Android.Extensions.JavaObjectExtensions.ToObject(Object this, Type targetType)
   at Plugin.Firebase.Firestore.Platforms.Android.Extensions.JavaObjectExtensions.Cast(IDictionary this, Type targetType, String documentId)
   at Plugin.Firebase.Firestore.Platforms.Android.Extensions.JavaObjectExtensions.Cast[Route](IDictionary`2 this, String documentId)
   at Plugin.Firebase.Firestore.Platforms.Android.DocumentSnapshotWrapper`1[[GRVL.Data.Route, GRVL, Version=1.0.0.0, Culture=neutral, PublicKeyToken=null]].get_Data()

Any pointers as to what might be causing this, or how to fix this would be greatly appreciated.

Thanks a stack
