Flutter with Realm

I’ve been looking at the examples for Realm and Flutter and I’ve come across an error that I don’t know how to work around.
Realm Flutter documentation
github: realm-dart-samples

I’ve bumped up my Flutter SDK to

flutter --version
Flutter 3.1.0-0.0.pre.1533 • channel master • https://github.com/flutter/flutter.git
Framework • revision 78e3b93664 (18 hours ago) • 2022-07-07 08:34:06 -0400
Engine • revision 56faff459e
Tools • Dart 2.18.0 (build 2.18.0-261.0.dev) • DevTools 2.15.0

The error is when I try to run the apps from the repository:

flutter  run

This error shows that realm native binary was correctly loaded into the app and most probably it happens cause there are no network entitlements on the app. You can read how to add them here Networking | Flutter
and Building macOS apps with Flutter | Flutter

You can also try running this Flutter sample which does not have network requirements realm-dart-samples/provider_shopper at master · realm/realm-dart-samples · GitHub

Also bumping the Flutter version to Flutter Beta is not required. Consider using the stable version of Flutter.

@Ilan_Toren We have fixed our sample with the correct entitlements. Can you get the latest master and try running it again.

So far it looks good. And I have the dart_flexible_sync working. Thanks for your response, because now I can put together the Flutter UI app I want to get off the ground.
