Light aircraft pilot reported a NMAC entering the pattern at BKV. Pilot took evasive action and landed uneventfully.

Narrative

I was conducting a flight to BKV via the gulf coast shoreline; which runs the western boundary of the Tampa Class B Airspace. I was acting as Pilot in Command; with 256.5 total hours; 58.3 in the last 90 days; and 18.9 hours time in type. Roughly 8 NM (Nautical Miles) from the field; Tampa Approach Control instructed me to contact BKV Tower. On initial contact; I stated that I was 8 NM to the southwest and was requesting inbound with a full stop landing. The controller acknowledged and instructed me to proceed inbound; report 4 NM for the left downwind to runway 27. Due to congestion on the frequency; I was unable to make a position report at 4 NM; and my report was made at around 3 NM. The controller acknowledged; and instructed me to enter the left downwind for runway 27. Shortly thereafter; I began receiving an ADS-B traffic alert on the multifunction display in the aircraft as well as through ForeFlight on my iPad. I began looking for the traffic and had not been giving any traffic alert from BKV Tower. Due to the high glare shield and low seat mounting of the CRUZ; visually identifying opposite direction; same altitude traffic is difficult. About 30 seconds later; the traffic came into view off the right size of the nose of the aircraft; which appeared to be a low-wing single engine land aircraft. The other aircraft was moving opposite direction at the same altitude; and passed less than 100ft off my right wing. Evasive action was taken to avoid a collision. I immediately contacted BKV Tower; stating that another aircraft had passed opposite direction; same altitude at a very concerningly close distance. The tower controller stated that he was aware; and that other aircraft was going to follow me into the downwind. The controller did not appear to show any concern for the situation or acknowledge that no traffic alert had been provided to me. It is my opinion that had I began the turn into the downwind leg of the pattern; a midair collision would have occurred. The remainder of the flight was uneventful. For context; BKV Tower is a non-radar; VFR tower.
