Animation Rigging is an official Unity package allowing to manipulate a character rig to create procedural secondary animations.

As Animation Rigging relies on Playables, it has compatibility issues with custom packages also using Playables like FlexMotion.

To address this issue, I created a dedicated component to bind the Animation Rigging's Rig Builder component with a FlexMotionAnimator.

To use it simply add the FlexMotionRigBuilderBinder component to the same GameObject as the FlexMotionAnimator. Then fill the RigBuilder serialized field with the corresponding component.

This is typically how you would configure Animation Rigging and the Rig builder binder:
