I added maplibre_gl as a Custom Pub Dependency in Project Dependencies (tested versions ^0.20.0 and ^0.27.0). It appears correctly listed with the version set. However, my Custom Widget (EnziMap) still shows the compile error "Target of URI doesn't exist: 'package:maplibre_gl/maplibre_gl.dart'" and all subsequent errors depending on it (undefined classes MaplibreMapController, CameraPosition, MaplibreMap, etc).
