Build fails after upgrade to flutter 3.0 #330

stingrayx · 2022-05-12T06:55:00Z

Hello,

just wanted to let you know that there seems an issue with the latest flutter release 3.0 and this plugin.

After upgrading my flutter the build of my app using background_locator 1.6.12 gives following errors:

background_locator\android\src\main\kotlin\rekab\app\background_locator\BackgroundLocatorPlugin.kt: (25, 1): Class 'BackgroundLocatorPlugin' is not abstract and does not implement abstract member public abstract fun onNewIntent(p0: Intent): Boolean defined in io.flutter.plugin.common.PluginRegistry.NewIntentListener

background_locator\android\src\main\kotlin\rekab\app\background_locator\pluggables\InitPluggable.kt: (22, 55): Type mismatch: inferred type is BinaryMessenger? but BinaryMessenger was expected

Best regards
Thomas

Just in case someone is experiencing the same issue. Seems that the fork here has already a fix for this problem!

sterrana · 2022-05-12T12:32:03Z

I just updated to 3.0 and this package raises a lot of errors.
With the fork above a big part of warnings are resolved, but in my case I had to manually activate MultiDex and remove ! from background_locator.dart (line 34).

@caiobraga do you think you could fix your branch accordingly to @sterrana's comment ?

Can you please post a build logs here.

kivocsa99 · 2022-05-16T06:49:00Z

@Alfaizkhan iam going to build now but long story short , it first asked me to upgrade my compile and target SDK versions to 31
then there is the whole ->

Execution failed for task ':background_location:compileDebugKotlin'.

I'm getting this issue when I run it in the emulator:

Running Gradle task 'assembleDebug'...
e: D:\develop\flutter.pub-cache\git\background_locator-08beb61507f472de767fa918365fa2601c879c63\android\src\main\kotlin\rekab\app\background_locator\provider\LocationParserUtil.kt: (21, 20): Type mismatch: inferred type is String? but Any was expected

FAILURE: Build failed with an exception.

What went wrong:
Execution failed for task ':background_locator:compileDebugKotlin'.

Compilation error. See log for more details

For anyone with this error:

background_locator/provider/LocationParserUtil.kt: (21, 20): Type mismatch: inferred type is String? but any was expected

just find the LocationParserUtil.kt file in your directory and replace it with the following code snippet:

package rekab.app.background_locator.provider

import android.location.Location
import android.os.Build
import com.google.android.gms.location.LocationResult
import rekab.app.background_locator.Keys
import java.util.HashMap

class LocationParserUtil {
     companion object {
         fun getLocationMapFromLocation(location: Location): HashMap<Any, Any> {
             var speedAccuracy = 0f
             if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.O) {
                 speedAccuracy = location.speedAccuracyMetersPerSecond
             }
             var isMocked = false
             if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.JELLY_BEAN_MR2) {
                 isMocked = location.isFromMockProvider
             }

             return hashMapOf(
                 Keys.ARG_IS_MOCKED to isMocked as Any,
                 Keys.ARG_LATITUDE to location.latitude as Any,
                 Keys.ARG_LONGITUDE to location.longitude as Any,
                 Keys.ARG_ACCURACY to location.accuracy as Any,

                 Keys.ARG_HEADING to location.bearing as Any,
                 Keys.ARG_TIME to location.time.toDouble() as Any,
                 Keys.ARG_PROVIDER to location.provider as Any
             )
         }

         fun getLocationMapFromLocation(location: LocationResult?): HashMap<Any, Any>? {
             val firstLocation = location?.lastLocation ?: return null

             var speedAccuracy = 0f
             if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.O) {
                 speedAccuracy = firstLocation.speedAccuracyMetersPerSecond
             }
             var isMocked = false
             if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.JELLY_BEAN_MR2) {
                 isMocked = firstLocation.isFromMockProvider
             }

             return hashMapOf(
                 Keys.ARG_IS_MOCKED to isMocked as Any,
                 Keys.ARG_LATITUDE to firstLocation.latitude as Any,
                 Keys.ARG_LONGITUDE to firstLocation.longitude as Any,
                 Keys.ARG_ACCURACY to firstLocation.accuracy as Any,
                 Keys.ARG_ALTITUDE to firstLocation.altitude as Any,
                 Keys.ARG_SPEED to firstLocation.speed as Any,
                 Keys.ARG_SPEED_ACCURACY to speedAccuracy as Any,
                 Keys.ARG_HEADING to firstLocation.bearing as Any,
                 Keys.ARG_TIME to firstLocation.time.toDouble() as Any
             )
         }
     }
}
