I've imported an old project into a new android studio/flutter install. Having major issues trying to deploy my app to an android device. I had to change my targetSdkVersion from 27 to 32, because if I don't, this new version of Gradle throws errors. with targetSdkVersion 32 set, the most recent version of location I can use is 'location: ^3.2.4'. Can't use 4 otherwise I get conflicts with other dependencies.

Now I'm getting this error:

FlutterLocationService.kt: (149, 5): 'onRequestPermissionsResult' overrides nothing

I have searched it and I can't make sense of this solution: 'onRequestPermissionsResult' overrides nothing

I've tried the solutions posted here: https://github.com/Lyokone/flutterlocation/issues/698

None worked for me.

Changing

override fun onRequestPermissionsResult(requestCode: Int, permissions: Array<out String>?, grantResults: IntArray?): Boolean

to

override fun onRequestPermissionsResult(requestCode: Int, permissions: Array<out String>, grantResults: IntArray): Boolean 

results in the following error:

e: C:\src\flutter\.pub-cache\hosted\pub.dartlang.org\location-3.2.4\android\src\main\java\com\lyokone\location\FlutterLocationService.kt: (149, 5): Conflicting overloads: public open fun onRequestPermissionsResult(requestCode: Int, permissions: Array<out String>, grantResults: IntArray): Boolean defined in com.lyokone.location.FlutterLocationService, public open fun onRequestPermissionsResult(requestCode: Int, permissions: Array<out String>, grantResults: IntArray): Boolean defined in com.lyokone.location.FlutterLocationService

FAILURE: Build failed with an exception.

* What went wrong:
Execution failed for task ':location:compileDebugKotlin'.

so there is some sort of conflict here?:

    override fun onRequestPermissionsResult(
        requestCode: Int,
        permissions: Array<out String>,
        grantResults: IntArray
    ): Boolean {
        TODO("Not yet implemented")
    }
}

edit: I tried implementing the code posted by user: gustysetyono.

result:

Exception: Unsupported Android Plugin version: 4.2.2.

edit: here's more info on the above exception:

I don't understand. Anybody know how to resolve this?

CodePudding user response：

Nothing fixed this mess. I ended up having to pull an old version of my code and update everything manually. flutter SDK is terrible.

CodePudding user response：

Changing

override fun onRequestPermissionsResult(requestCode: Int, permissions: Array?, grantResults: IntArray?): Boolean

to

override fun onRequestPermissionsResult(requestCode: Int, permissions: Array, grantResults: IntArray): Boolean

This fixed your first issue, the second one is related to the Flutter package location that your plugin depends on, update it and I guess it should work, also return something in the function since it expects a boolean

Clean the project, maybe Android Studios' cache too

HIH.
