Hello @fryette,
Your implementation does not make sense. A mvt/pbf contains the vector data of a single map tile while mbtiles is an archive of multiple tiles.

@josxha strange, then why support mentioned in the readme?
Supported vector tile format: pbf (sometimes known as mvt)
here: https://github.com/josxha/flutter_map_plugins/tree/main/flutter_map_mbtiles

The tiles within a mbtiles archive have a format like for example png for raster tiles or pbf for vector tiles. But the package expects the complete mbtiles file as input, not individual tiles.
See the mbtiles specification here: https://github.com/mapbox/mbtiles-spec/blob/master/1.3/spec.md#content
