core.js:13987 'app-flower-spinner' is not a known element:

[ShivamShokeen]

<app-atom-spinner [animationDuration]="animationDuration" [size]="100" [color]="'#ff1d5e'"
></app-atom-spinner>

The above is working but when I added the below one it throws an error of 'core.js:13987 'app-flower-spinner' is not a known element:'.

 <app-flower-spinner
 [animationDuration]="2500"
 [size]="70"
 [color]="'#ff1d5e'"
></app-flower-spinner>

Did you import the FlowerSpinnerModule in your app.module.ts ?
