Cessna 206 pilot on final approach to a non-towered airport reported a NMAC with an aircraft departing opposite direction.

Narrative

C206 PIC checked the AWOS for ZZZ and heard winds reported XXX at 2 which favors a rwy XX landing. No ceiling was reported. No visibility issues were reported. Altimeter was 30.24. No other aircraft were in the traffic pattern. C206 PIC entered a 45 degree entry to the downwind for rwy XX and made a radio call on the UNICOM. C206 PIC turned base for rwy XX and made a radio call on the UNICOM. C206 PIC turned final for rwy XX and made a radio call on the UNICOM. Upon rolling out wings level lined up with rwy XX centerline the C206 PIC saw another aircraft directly in front of them co altitude flying the opposite direction head on. C206 PIC immediately made an evasive maneuver to the right to avoid the mid air collision. C206 PIC executed a go-around and came back around for a full stop landing on rwy XX. The other plane was a Piper Archer III. Other pilot had just taken off from rwy XY at ZZZ at the time of the incident. Other pilot never made a radio call for taxi; never made a radio call for runup; never made a radio call for takeoff. Other pilot did not turn their transponder on before takeoff. The C206 is equipped with a G1000 and would have received a TCAS alert had the other plane been altitude reporting but never did. C206 PIC had no human factors contributing to the incident.
