moveCamera method

Implementation

@override
void moveCamera(latlong.LatLng location, double? zoom) async {
  // First approach, simpler but less accurate
  // final controller = await mapController.future;
  // final visibleRegion = await controller.getVisibleRegion();

  // // Calculate padding offset
  // final paddingOffset = LatLng(
  //   (visibleRegion.northeast.latitude - visibleRegion.southwest.latitude) *
  //       (padding.top - padding.bottom) /
  //       viewportSize.height,
  //   (visibleRegion.northeast.longitude - visibleRegion.southwest.longitude) *
  //       (padding.left - padding.right) /
  //       viewportSize.width,
  // );

  // controller.animateCamera(
  //   CameraUpdate.newCameraPosition(
  //     CameraPosition(
  //       target: LatLng(
  //         location.latitude + paddingOffset.latitude,
  //         location.longitude + paddingOffset.longitude,
  //       ),
  //       zoom: zoom ?? 16,
  //     ),
  //   ),
  // );
  // Second approach, more complex but should be more accurate
  // final c = await mapController.future;

  // // Use current zoom if not provided
  // final currentZoom = await c.getZoomLevel();
  // final targetZoom = zoom ?? currentZoom;

  // // Where the "center" of the padded viewport actually is (in screen px)
  // final paddedCenterX =
  //     (viewportSize.width / 2) + (padding.left - padding.right) / 2;
  // final paddedCenterY =
  //     (viewportSize.height / 2) + (padding.top - padding.bottom) / 2;

  // // Find the lat/lng that appears at that padded center
  // final targetScreen = ScreenCoordinate(
  //   x: paddedCenterX.round(),
  //   y: paddedCenterY.round(),
  // );
  // final latLngAtPaddedCenter = await c.getLatLng(targetScreen);

  // // Compute the lat/lng shift needed so `location` ends up at the padded center
  // final dx = location.latitude - latLngAtPaddedCenter.latitude;
  // final dy = location.longitude - latLngAtPaddedCenter.longitude;

  // await c.animateCamera(
  //   CameraUpdate.newCameraPosition(
  //     CameraPosition(
  //       target: LatLng(
  //         location.latitude +
  //             dx, // effectively centers location at padded center
  //         location.longitude + dy,
  //       ),
  //       zoom: targetZoom,
  //     ),
  //   ),
  // );

  // Third approach, simpler and should be accurate enough
  final c = await mapController.future;
  final currentZoom = await c.getZoomLevel();
  await c.animateCamera(
    CameraUpdate.newLatLngZoom(
        location.toGoogleMapLatLng(), zoom ?? currentZoom),
  );
