mbtilesToPngs
This python program takes .mbtiles files and extracts the images and places them into the correct directory structure /${z}/${x}/${y}.png that mimicks OpenStreetMap URI tile structure. This is to allow for offline use of OpenStreetMaps, and I will be using Flutter_Map along with my own images for offline maps.
Where to get .mbtiles?
OpenStreetMap says: Apart from very limited testing purposes, you should not use the tiles supplied by OpenStreetMap.org itself. OpenStreetMap is a volunteer-run non-profit body and cannot supply tiles for large-scale commercial use. Rather, you should use a third party provider that makes tiles from OSM data, or generate your own.
This guide will go through the steps for compiling map data, downloading a specific area, customise the map, then export to mbtile. Warning! For Mac, when you install TileMill.app, it currently fails to start. Go into TileMill > Updates Preference > check Install Developer Builds.
How to use
Make sure you have python3 install.
python3 mbtilesToPngs.py -i path_to_mbfiles
for example, I did:
python3 sqliteReader.py -i ./OSMBright.mbtiles
My map says file not found! Why are the filenames incorrect?

I've added option to convert TMS Tile Coordinates to Google/Bing/OSM Tile Coordinates. Just use -tms when running.
