Flutter with Segment Analytics

Question

I am trying to add Segment-Analytics to a Flutter app but currently, after adding the lib my app seems to be unable to start, however the build was still successful. lib: https://pub.dev/packages/flutter_segment

when i run flutter run:

Waiting for iPhone 12 Pro Max to report its views...
Debug service listening on ws://127.0.0.1:60371/UvkZwEEEE9Q=/ws
Syncing files to device iPhone 12 Pro Max...
Lost connection to device.

with verbose Ending few lines:

[   +2 ms] Updating assets
[ +800 ms] Manifest contained wildcard assets. Inserting missing file into build graph to force rerun. for more information see #56466.

any suggestions on how to work around for flutter to be able to send analytics data to segment analytics, from the web app it doesn't support it for the moment.

P/S: Any alternative SW suggestions would also be helpful thanks.

Add the Segment write-key to the native configuration, this would resolve it for now. there is an open issue - https://github.com/claimsforce-gmbh/flutter-segment/issues/87
