I'm correcting your code

https://stackblitz.com/edit/angular-hfrx5u

you must install an import in app.module.ts

angular material
import a MatInputModule

for reactive forms input ReactiveFormsModule

 import { FormsModule, ReactiveFormsModule } from '@angular/forms';
 import {MatInputModule} from '@angular/material/input';  

 and in NgModule

imports:[ BrowserModule, FormsModule, ReactiveFormsModule, MatInputModule],

Somebody helped me with my error. I corrected it in my stackblitz.

I didn't give a good property for my arrayItems.

Before (incorrect):

arrayItems= []

After (correct):

arrayItems: any[] = [];
