Flutter map get address - flutter

Question

This is all my code. I want it to be able to search for places from lat , lng , and if lat,lng is not there, it will search for places from names. But now it's like when searching for a place from the name. In the part where the name is converted to lat,lng it's correct but my marker appears in the middle of the sea
LatLng centerMap = LatLng(13.730452094709594, 100.64180575311175);
#override
void initState() {
findLocation();
super.initState();
}
void findLocation() async {
var lat = double.tryParse(searchitems[0].address![widget.index].latitude.toString());
var lng = double.tryParse(searchitems[0].address![widget.index].longitude.toString());
if (lat != null && lng != null) {
centerMap = LatLng(lat, lng);
} else {
var name = searchitems[0].name;
var addr = '${searchitems[0].address![widget.index].addr1!}, ${searchitems[0].address![widget.index].thanon!}, ${searchitems[0].address![widget.index].tambon!}, ${searchitems[0].address![widget.index].province!}';
var addresses = await Geocoder.local.findAddressesFromQuery(addr);
var first = addresses.first;
centerMap = LatLng(first.coordinates.latitude!, first.coordinates.longitude!);
print("Location not found, searching for name: $name and address: $addr");
}
print("map:$centerMap");
}
GoogleMap(
initialCameraPosition: CameraPosition(
target: centerMap,
zoom: 16.0,
),

Answer 1

You can add a controller in Google maps, then when you call the API and get new lat long, you can animate camera to that position like this:
Future<void> _goToNewPosition() async {
final GoogleMapController controller = await _controller.future;
controller.animateCamera(CameraUpdate.newCameraPosition(_kLake));
}
There's also an example on the official package, you can check it out by this link
