Hello, I am new to Amity, and I have been trying to integrate the Flutter Amity SDK UI Kit on a new Flutter project. No dependencies, just amity\_uikit\_beta\_service.
But, I can’t seem to get past these errors, possibly because of dependency issues:
My Flutter environment sdk is ‘\>=3.2.3 \<4.0.0’.
**Errors:**

Just to clarify, @SocialPlus_Support, how do I go about integrating the new changes?
Do I add the SDK as a dependency pointing to a particular Github branch?
Or is it the usual:
dependencies:
flutter:
sdk: flutter
cupertino\_icons: ^1.0.2
amity\_uikit\_beta\_service: ^0.2.0
Kindly advise on way forward.
