I get a problem using native plugin ionic 3 when install Native Store is success, but when I try to add in app module, the text editor show a red line and when I try to run
Goto https://www.npmjs.com.
Search for the ionic-native package that you want to install.
In your case, its 'ionic-native-storage'. Check the versions and choose the one which was released before the Ionic 4 Beta release and then install the appropriate version using the same command.
ionic cordova plugin add cordova-plugin-nativestorage@"====add your version here===="
After that the plugin will work the same way as it did. No need to fiddle with adding 'ngx' at the end of the path.
