First of all polylines added are placed wrong. you can follow my answer to generate then correctlly : https://stackoverflow.com/a/58831792/7910735

And for your Question you should use CameraUpdate.newLatLngBounds() just after placing the polylines.

Somewhat similiar to this

void animateCameraForOD() {
    mapController.animateCamera(
      CameraUpdate.newLatLngBounds(
          LatLngBounds(
                southwest: LatLng(
                    fromLocationLatLng.latitude <= toLocationLatLng.latitude
                        ? fromLocationLatLng.latitude
                        : toLocationLatLng.latitude,
                    fromLocationLatLng.longitude <= toLocationLatLng.longitude
                        ? fromLocationLatLng.longitude
                        : toLocationLatLng.longitude),
                northeast: LatLng(
                    fromLocationLatLng.latitude <= toLocationLatLng.latitude
                        ? toLocationLatLng.latitude
                        : fromLocationLatLng.latitude,
                    fromLocationLatLng.longitude <= toLocationLatLng.longitude
                        ? toLocationLatLng.longitude
                        : fromLocationLatLng.longitude)),100),
    );
  }

It will make your both LatLngs to be zoomed out to be in the given bounds with padding also.
