/*
In this example, we create a sample Firestore document with a Timestamp value and then use the MapDescriptor package to convert the Timestamp value to a String. We then print the converted data to the console.

Next, we use the convertStrToTimeStamp method to convert the String value back to a Timestamp. We pass in the convertedData map and specify the key where the Timestamp is located (timeStampsKeys: [['timestamp']]). We then print the converted back data to the console.
