Ionic 3 - sqlite shows error of "can not read property of openDatabase" when run with --prod flag

I am using cordova-sqlite-ext in ionic 3 project. My code is working fine when run without --prod flag.

But when i run ionic cordova run android --prod --relase it shows "can not read property of openDatabase"

here is my code

  export class SqlLiteServiceProvider {
  private options = {name: 'db.db', location: 'default',existingDatabase: 1,createFromLocation:1};
  public win = (<any>window);
  private db : any;

  constructor() {
    try{
      if(this.win.cordova){
        this.db = this.win.sqlitePlugin.openDatabase(this.options);

      }else{
        this.db = this.win.openDatabase(this.options.name, '1.0', 'database', 5 * 1024 * 1024);
      }
  }catch(ex){
    alert(ex); // always alert error when run with --prod flag
  }
  }
}

You cannot run ionic cordova run android --prod --relase with on debug mode. It is for google play store release build. If you need to test on your device you should run below CLI.

ionic cordova run android --prod --device

When you do a production build the window object is handled differently as far as I know. When using cordova-plugins which are not included in ionic-native you need to do things a bit different.

Tell typescript that you are sure your plugin handle exists somewhere after the build:

declar var SQLitePlugin; // add this at the same level as imports

And to use it for example in ngOnInit():

ngOnInit() {
  SQLitePlugin.openDatabase(...);
}

But instead of doing this I strongly recommend you using @ionic/storage or @ionic-native/sqlite.
