How to use FLOSS Geolocator for Flutter applications:

Import normal geolocator as known. You may also use other packages using geolocator as dependency.

dependencies:
  flutter:
    sdk: flutter
  geolocator: ^7.6.2

To use FLOSS geolocator (e.g. only for the FLOSS builds), you can simply add a dependency override. This ensures other dependencies using geolocator are forced to use the FLOSS version too:

dependency_overrides:
  geolocator_android:
    hosted:
      name: geolocator_android
      url: https://hanntech-gmbh.gitlab.io/free2pass/flutter-geolocator-floss

Please note the override no longer overrides geolocator but geolocator_android.

https://gitlab.com/free2pass/flutter-geolocator-floss.git is not available now.

Was moved to https://gitlab.com/hanntech-gmbh/free2pass/flutter-geolocator-floss. It actually properly redirects.

Thanks to a nice discussion with @KrilleFear, the FLOSSed Flutter geolocator now got rid of the ugly git override and provides its own package automatically created server in CI/CD jobs. This permits to drop in the FLOSSed version once without any later modifications like e.g. updated versions / refs or Git imports in production builds. This was realized by a little utility called repo_pub_server.

For the latest version of the geolocator override, use this for your pubspec:

dependency_overrides:
  geolocator_android:
    git:
      url: https://github.com/Zverik/flutter-geolocator.git
      ref: floss
      path: geolocator_android

[Flutter] Working with dependencies that rely on GMS

If the following matches to you:

• You use Flutter
• You develop two variants (or more) of your app, of which
  • one relies on GMS related dependencies and
  • the other one should be completely libre (without any GMS) and
• one dependency that depends on GMS does not work in the libre version, even when you wouldn't use it

you can try the following workaround. Note that I am completely disabling the functionality here in the FLOSS version.

1. Create a local Flutter package and name it exactly like your dependency (for reference: https://docs.flutter.dev/packages-and-plugins/developing-packages): flutter create --template=package dependency_name_here
2. Copy the classes, functions, etc. and make them empty / write throw UnimplementedError
3. In your pubspec.yaml, use dependency_override to override the package with your local one

Example

This was all a bit abstract, let's see a real example.

Context I have a project (https://github.com/Myzel394/locus) that should be built for two variants: GMS and FLOSS. For the GMS variant, I wanted to add Bluetooth file sharing support. To achieve this, I used the nearby_connections package. Unfortunately this resulted in some things not working in the FLOSS variant anymore. The reason for this is a bit complicated, see this issue for more info.

Since I was okay with the GMS variant only having the Bluetooth file sharing functionality, it was very easy to get the app up and running again using this workaround. Here's what I did:

• I created a folder at the root called dependency_overrides
• Inside the folder I created a local Flutter package: flutter create --template=package nearby_connections
• I copied all classes, functions, enums, etc. from nearby_connections and made them empty. See this folder for more - especially this file contains all the "fake" classes, functions. etc
• Inside my pubspec.yaml, I'm overriding the dependency when building for FLOSS
• And now everything is running and working again! 🥳

To see the full example, take a look at the app (and don't forget to leave a star :D)
