Fix deprecation messages when building the app #1035
Description
This has already been pointed out in #976, #1000, #1019, #1022 and #1023. I'm creating this issue as an attempt to centralize the discussion and finally solve the deprecation messages shown when compiling the app.
Versions used:
flutter: 3.32.5
dart: 3.8.1
location: 8.0.1
Let's start from the beginning:
When the app is compiled (flutter build apk) this message shows up
When we recompile it with the -Xlint:deprecation flag we get what's going on

Looking at the Gradle Problem Report, we have this
We can see that 13 problems has to do with the FlutterLocation.java trying to access deprecated properties from the com.google.android.gms.location.LocationRequest and com.google.android.gms.location.
The other 2 problems are from MethodCallHandlerImpl.java where we try to access the java.lang.Long and java.lang.Float, which are both deprecated
This thread in StackOverflow explains how we can fix it, basically migrating from LocationRequest.PRIORITY_HIGH_ACCURACY to Priority.PRIORITY_HIGH_ACCURACY
Projects like geolocator have already addressed issues like this, as we can see in geolocator#828. We can take it as a reference to solve it here.
How to reproduce the problem?
- Create a new flutter project
- Add the location as a dependency
- Build the project (
flutter build apk)
What do you guys think about it? Can we focus on solving this issue?
