Question How to manipulate 3D character in Unity being embeded in Flutter using pose detection?

Ok so my project is to manipulate 3D characters in real-time using the users kinematics. For kinematics, i am using Google ML kit pose detection to get the landmarks of every joint. and As flutter does not support any 3D rendering so for that i am embedding a unity app inside a flutter so i can detect values in flutter using the camera and send those landmarks to unity module/app. i tried using animation rigging in unity but the points are not matched as it should. SO my question is or is there any resource for manipulating 3D characters using those points.
