@jiayihu I think this is good enough
If we want to check there is a transform we do

!!canvas.getActiveObject().getActiveControl()

[ShaMan123]

naming suggestion are welcome (corener is misleading, a control can be anywhere)
besides that DONE

!!canvas.getActiveObject().getActiveControl()

Sometimes you can have an active control without an active object, e.g. a hover button that can be clicked without first selecting the object. So ideally it should be canvas.getActiveControl() IMO. @ShaMan123

Maybe the same method can be added to the canvas as this:

getActiveControl() {
  return this.getActiveObject()?.getActiveControl() ?? this._currentTransform?.target.getActiveControl()
}

Good point
