flutter adding geolocator to project giving errors

问题

I'm trying to use geolocator to get users location. However after installing dependencies and running it. I get a ton of errors. When I remove it and rerun, all errors are gone. I've tried multiple versions of the plugin and still same error. Here's my log output:

WARNING: This version of firebase_core will break your Android build if it or its dependencies aren't compatible with AndroidX.
         See "url" for more information on the problem and how to fix it.
         This warning prints for all Android build failures. The real root cause of the error may be unrelated.

I even commented out the firebase_core one thinking it might be conflicting with geolocator, but I'm still getting the same error. Here are my dependencies:

dependencies:
  google_maps_flutter: ^0.0.3+3
  geolocator: ^3.0.0
  http: ^0.12.0
  flutter:
    sdk: flutter
  # The following adds the Cupertino Icons font to your application.
  # Use with the CupertinoIcons class for iOS style icons.

  cupertino_icons: ^0.1.2
  firebase_auth: ^0.5.8
  #firebase_core: ^0.3.0+2
  firebase_database: ^2.0.1+1

Any ideas? Thanks

回答1:

It's that some of the libraries you depend on supports AndroidX while the others don't. For AndroidX -less solution

Try replacing:

geolocator: ^3.0.0

with:

geolocator: ^2.1.1
permission_handler: "2.1.2"
google_api_availability: "1.0.4"

More info here, here and here.
