Implements Amplitude with flutter_segment package

[RicharC293]

We are trying to implement this package for segment and amplitude integration all at the flutter level.
https://pub.dev/packages/flutter_segment
https://pub.dev/packages/flutter_segment#setting-the-options-globally

The flutter_segment package to identify the user asks me for a session_id but when trying to get this session_id with the amplitude package it always returns -1.

My question is, what would be the best practice to integrate these two packages, maybe there is any suggestion?

As far as I understand I need to identify the user to get a session Id, maybe it works in a similar way with the anonimus id that segment provides?

Hi @RicharC293. Does the issue is when you trying to get session id from amplitude_flutter the session id always be -1? Without the implementation details, we cannot find the real cause is. May I know which version of amplitude_flutter you are using and how you get the session id?

Sometimes when i call getSessionId() return session id but in other cases return -1

Code to call session_id implemented

static Future<int> _getAmplitudeSessionId(User user) async {
    try {
      final Amplitude analytics =
          Amplitude.getInstance(instanceName: "client_mobile");
      analytics.setUseDynamicConfig(true);
      analytics.setServerUrl("https://api2.amplitude.com");
      analytics.init(Flavor.amplitude, userId: "${user.userId}");
      analytics.trackingSessionEvents(true);
      print(await analytics.getSessionId());
      return await analytics.getSessionId();
    } catch (err) {

      return null;
    }
  }

Did you ever find the solution to this problem? We see the same thing where the session ID defaults to -1 in Amplitude because intergrations.Actions Amplitude.session_id is blank in Segment for the event integrations parameter.
