title: Reac leaflet TileLayer not serving local tiles in png format
body: <p>I am using react leaflet and I wanted to be able to use offline maps. Hence I downloaded tiles I was interested in, convert them into png and save them locally. But when I use this code :
   <a href="https://i.stack.imgur.com/yQ1kc.png" rel="nofollow noreferrer">OpenStreetMap</a> contributors'
            url="local.mbtiles/{z}/{x}/{y}.png"/>
  I receive error: 1614.png:1 GET <a href="http://localhost:8080/local.mbtiles/12/3635/1614.png" rel="nofollow noreferrer">http://localhost:8080/local.mbtiles/12/3635/1614.png</a> 404 (Not Found). Can anyone please help?</p>
