Error in compilation with Geolocator pluggin - flutter

Question

I'm getting the current error when compiling a project with Geolocator pluggin:
C:\src\flutter\.pub-cache\hosted\pub.dartlang.org\geolocator_android-2.0.0\android\src\main\java\com\baseflow\geolocator\location\LocationMapper.java:29: error: cannot find symbol

I have already created another project to test if the error would occur, and when importing the package, the error occurs as well. I followed the gradle.properties configuration
and set the compileSdkVersion to 30 and checked the Flutter Doctor too, everything is ok, but the error still persists. Does anyone know what might be causing this?

Answer 1

I had the same trouble with geolocator 7.7.0. Here
To fix it, I changed in build.gradle compileSdkVersion from 29 to 31. That works for me.
android {
compileSdkVersion 31
defaultConfig {
minSdkVersion 21
targetSdkVersion 29
...
}
...
}

Answer 2

Try to change the targetSdkVersion and the compileSdkVersion to 31.
Don't forget to check this:
app/src/build.gradle:
minSdkVersion 20
gradle.properties:
android.useAndroidX=true
android.enableJetifier=true
I hope to help you!

Answer 3

In my case I changed the compileSdkVersion to 30.
android {
compileSdkVersion 30
defaultConfig {
minSdkVersion 21
targetSdkVersion 29
}
}
You should pin the geolocator to version 7.6.2 (without using the caret ^ character) like so:
geolocator: 7.6.2
If you don't Flutter will still upgrade the geolocator plugin to version 7.7.0. More information can be found here: https://dart.dev/tools/pub/dependencies#caret-syntax

I had same problem, i fix with download platform version sdkmanager "platforms;android-31", and change compileVersion 31, minSdkVersion 21, and targetSdk 31.
android {
compileSdkVersion 31
...
defaultConfig {
...
minSdkVersion 21
targetSdkVersion 31
...
}
}

Answer 5

I had the same problem after upgrade flutter to 3.0.3.
I have updated the geolocator plugin to version 9.0.0 and the problem was solved.
Now everything is working fine.
