which has every thing to make it compatible for aot . But while building my app with

ionic build --prod command , aot build fails with error shown below.

Answer 1

I followed the below steps and it worked for me hope it helps you

Step 1: install npm install ionic-scrolling-header --sav-dev

Step2: Open Your home.moduel.ts file and import this import {ScrollingHeaderModule} from 'ionic-scrolling-header'; and don't forget to add this inside your imports

imports: [
    ScrollingHeaderModule,
    IonicPageModule.forChild(HomePage),
  ],

Step3: Inside your home.ts file add this @ViewChild(Content) content: Content;

Step 4: inside your home.html page add this <ion-header [scrollingHeader]='content'>

0-Download project from author repository
1-Rename "src" folder to "ionic-scrolling-header", and copy to your directive(folder)
2-Create a directive folder inside src (folder)
3-Change import in your app.module.ts, as you can see on my print:
