matTextareaAutosize does not work in Angular Material 6.4.2

Question

I am trying apply auto-sizing on textarea in angular material 6.4.2 like below -

<mat-form-field>
      <textarea matInput [matTextareaAutosize]="true" placeholder="Task description" formControlName="description" [errorStateMatcher]="ErrorMatcher">
       </textarea>
</mat-form-field>

But it is throwing following error: Can't bind to 'matTextareaAutosize' since it isn't a known property of 'textarea'

What the wrong in my code?

Answer 1

in you app.moudle

import {  MatInputModule } from '@angular/material';

and then add MatInputModule to your app.moudle imports
