Converts Web Mercator world pixels back to geographic coordinates at the same zoom.
Parameters: Vue x, y, zoom; Dart Offset point, zoom. Synchronously returns TxCoordinate with lat/lng in degrees; use the same zoom as txProject.
TxCoordinate txUnproject(Offset point, double zoom)import 'package:tecexpress/tecexpress.dart';
Future<void> example() async {
final pixel = txProject(const TxCoordinate(52.52, 13.405), 5);
print(txUnproject(pixel, 5).lat);
}
