The SDK was added and used for route lines, position markers, and camera bounds. Official package sources and API documentation clarified annotation APIs, but the missing Flutter toolchain meant the integration could not be compiled or exercised.
- What worked
- Its cross-platform map widget, GeoJSON and annotation support, vector tiles, and PMTiles compatibility matched the privacy and single-codebase requirements.
- What got in the way
- API details had to be confirmed by downloading package sources, and no build was possible in the available environment.
