Publishing to Play Store and App Store #
Android #

You can use appbundle to publish the app
Add this to your files in android folder (special thanks to https://github.com/nizwar/openvpn_flutter/issues/10). Otherwise connection will not be
established in some cases and will siliently report "disconnected" when trying to connect. Most likely it's related to some symbols stripping by
Google Play.

gradle.properties > android.bundle.enableUncompressedNativeLibs=false
AndroidManifest > android:extractNativeLibs="true" in application tag
