Update by animation Symbol

[ezesoftchao]

this is what i did

LatLng newLatLng = LatLng(lat, lng);

Timer.periodic(const Duration(milliseconds: 10), (timer) async {
LatLng currentLocation = symbol.options.geometry as LatLng; // LatLng of Symbol you want update

LatLng dynamicLocation = LatLng(
  currentLocation.latitude +
      (newLatLng.latitude - currentLocation.latitude) / 200,
  currentLocation.longitude +
      (newLatLng.longitude - currentLocation.longitude) / 200,
);
try {
  await _mapController.updateSymbol(
    symbol,
    SymbolOptions(
      geometry: dynamicLocation,
    ),
  );
} catch (e) {
  timer.cancel();
  return;
}

});

It is the basis of the idea and it can be improved much more.
I hope it works for you
