Donot works in release apk - java.lang.IllegalAccessError

[Satendra124]

When i try to run the flutter run --release the app opens and when mapbox needs to be shown then it crashes. Commenting the mapbox code the app works fine so am guessing there is some problem with the plugin.

MapboxMap(
            compassEnabled: true,
            initialCameraPosition:
                CameraPosition(target: LatLng(25.265, 82.991), zoom: 13.5),
            onMapCreated: _onMapCreated,
            accessToken: ACCESS_TOKEN,
            myLocationEnabled: true,
            myLocationTrackingMode: MyLocationTrackingMode.TrackingGPS,
            myLocationRenderMode: MyLocationRenderMode.GPS,
            onMapClick: (point, latLng) async {},
            onMapLongClick: (point, latLng) async {},
            styleString:
                "mapbox://styles/satendra124/ckll3sr9q0t4317lnzo5zg2nj",
          ),

this is the error I get in log:

Please help

This is an open issue in flutter with Android Gradle Plugin 4.0+. See flutter/flutter#58479 for the full discussion.

tl;dr downgrade android gradle plugin to 3.x and/or add the following proguard rule:

-keep class androidx.lifecycle.DefaultLifecycleObserver

Any update? I'm still experiencing this issue

[Satendra124]

Yes! Adding READ_PHONE_STATE permission in the manifest did the magic for me.
