A scalar quantity is one which has magnitude but no direction. A vector quantity is one which has both magnitude and direction. The direction of current is opposite to the flow of electrons.
Electric current has both magnitude and direction so ideally it 'should' be a vector. But all sources say it's a scalar just because it does not follow vector addition.
