title: Issues after Flutter upgrade
body: <p>I am completely lost.</p>
  <p>Last week I was working in a project that was running nice.</p>
  <p>Then I began working on another project and upgraded my Flutter version to the last version</p>
  <pre><code>Running flutter doctor...

  </code></pre>
  <p>Today I needed to make some changes in the project from last week, and suddenly I find out that the project has errors on 5 files.</p>
  <p>All errors are related to the package geocoder2.</p>
  <p>As example here you have where the issue is:</p>
  <pre><code> onSelected: (Place place) async {
                      FetchGeocoder fetchGeocoder =
                      await Geocoder2.getCoordinatesFromAddress(
                          address: place.description,
                          googleMapApiKey:
                          &quot;A---&quot;);
                      var first = fetchGeocoder.results.first;
  
                      var lat = first.geometry.location.lat;
                      var lng = first.geometry.location.lng;
                      LatLng sitio = LatLng(lat, lng);
  </code></pre>
  <p>The error says <code>Undefined class 'FetchGeocoder</code>, which was there before without issues.</p>
