I had the same problem with the app hanging on "installing build". But the solution for me was to include the package declaration at the top of package name.of.my.package; // <--- this is the important line
import com.transistorsoft.flutter.backgroundfetch.BackgroundFetchPlugin;
import io.flutter.app.FlutterApplication;
import io.flutter.plugin.common.PluginRegistry;
import io.flutter.plugins.GeneratedPluginRegistrant;
public class Application extends FlutterApplication implements PluginRegistry.PluginRegistrantCallback {
@Override
public void onCreate() {
super.onCreate();
BackgroundFetchPlugin.setPluginRegistrant(this);
}
@Override
public void registerWith(PluginRegistry registry) {
GeneratedPluginRegistrant.registerWith(registry);
}
} |
