Error: Type 'Geolocator' not found and 'Placemark' isn't a type


I am getting this error: Type 'Geolocator' not found and 'Placemark' isn't a type. Whenever I try to do flutter run, I get this error:

Why I ran into this problem, that, I am still figuring out.

How it started?

Before I did the flutter upgrade. While processing my electricity went, and this process got interrupted, due to this, flutter got corrupted.

What I did then?

I re-installed the Flutter, and then made some changes. Did these:

  1. Flutter pubspec.lock file removal
  2. Running flutter clean
  3. Running flutter run

It somehow removed my packages issue, but still I was getting the errors while running. Then I did that

flutter upgrade --force // which gave me that I am on stable and upgraded
flutter pub cache repair // which downloaded the packages again, except few failures which I ignored, not related to geolocator
flutter clean
flutter run

Again the same error, which I have mentioned above.

Now, what I am stipulating is, there are some sort of package deprecation problems, but I am already using the latest package that is geolocator 6.0.0+1

Show me flutter doctor -v or flutter doctor

How can I sort this out?


It was indeed a problem of the deprecated Geolocator() from the package geolocator. Now with the new flutter version 1.20.3 and geolocator 6.0.0+1, you need to use the package geocoder 0.2.1 to get the address.

Below code is fully deprecated and not supported at all:

    // for getting the position
    final Geolocator geolocator = Geolocator()..forceAndroidLocationManager;
        .then((Position position) {
      setState(() {
        _currentPosition = position;
    }).catchError((e) {

    // for getting location address
    List<Placemark> p = await geolocator.placemarkFromCoordinates(
          _currentPosition.latitude, _currentPosition.longitude);

      Placemark place = p[0];

      setState(() {
        _currentAddress =
            "${place.locality}, ${place.postalCode}, ${}";

To get the address you may now follow both geolocator and geocoder documentation. I am anyway pointing it out via my code:


  1. You get the position from Geolocator
  2. You can do the forceAndroidLocationManager: true, from Geolocator Position only
  3. You get the address from the Geocoder package


// you can play with the accuracy as per your need. best, high, low etc
// by default forceAndroidLocationManager is false
Position position = await getCurrentPosition(desiredAccuracy: LocationAccuracy.high, 
   forceAndroidLocationManager: true).catchError((err) => print(err));

// this will get the coordinates from the lat-long using Geocoder Coordinates
final coordinates = Coordinates(position.latitude, position.longitude);

// this fetches multiple address, but you need to get the first address by doing the following two codes
var addresses = await Geocoder.local.findAddressesFromCoordinates(coordinates);
var first = addresses.first;
print(place.countryName); // your country name will come. You can play with it to find out more

And this is how you fix the deprecated Geolocator code.
