Error: MissingPluginException(No implementation found for method locationFromAddress on channel flutter.baseflow.com/geocoding)

I want to convert some address to coordinates but I am getting this MissingPluginException error and it is caused by my locationFromAddress call and it prevents the navigator to function.
The code worked properly before I added locationFromAddress. What can this error mean and how do I fix this?
Error: MissingPluginException(No implementation found for method locationFromAddress on channel flutter.baseflow.com/geocoding)

my code

`import 'package:flutter/material.dart';
import 'package:flutter/scheduler.dart';
import 'package:geolocator/geolocator.dart';
import 'package:geocoding/geocoding.dart';

@OverRide
void didChangeDependencies() {
super.didChangeDependencies();
SchedulerBinding.instance.addPostFrameCallback((_) async {
userPosition = await getUserPosition();
locs = await GeocodingPlatform.instance.locationFromAddress('my address');
loc = locs.first;
if (context.mounted) {
Navigator.pushReplacementNamed(context, 'map', arguments: {
'userPosition': userPosition,
'loc': loc,
});
}
});
}

Position? userPosition;
Location? loc;
List locs = [];

@OverRide
Widget build(BuildContext context) {...}`
