I am trying to convert a firebase timestamp that has been returned from a could function to a date object in flutter.

I already tried those solutions but they didn't work: Converting timestamp

Here is the code I am using:


await firebaseFunctions
          .httpsCallable('functionName')
          .call({"data": data}).then((value) {
             Map<String, dynamic> map = value.data;
              DateTime dt = (map['dateOfPurchase'] as Timestamp).toDate();
              print(dt);
          });

The data that the map['dateOfPurchase'] attribut containes: {_nanoseconds: 665000000, _seconds: 1659266068}

The exception i get :

[ERROR:flutter/lib/ui/ui_dart_state.cc(198)] Unhandled Exception: type '_InternalLinkedHashMap<Object?, Object?>' is not a subtype of type 'Timestamp' in type cast

I found a solution to my own problem with this code

 await firebaseFunctions
          .httpsCallable('functionName')
          .call({"data": data}).then((value) {
            
             final map = Map<String, dynamic>.from(value.data['dateOfPurchase']);
             final seconds  = map["_seconds"];
             final nanoseconds  = map["_nanoseconds"];
             final Timestamp postConverted = Timestamp(seconds, nanoseconds);
             print(postConverted.toDate());
          });

Result of the print: 2022-07-31 13:14:28.665

I hope that could help some people who face the same problem then me.

If someone has a better solution don't hesitate to share it.
