Error in compilation with Geolocator pluggin

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

Execution failed for task ':geolocator_android:compileDebugJavaWithJavac'.
> Compilation failed; see the compiler error output for details.

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

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

Answer 3

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 4

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
        ...
    }
}
