Angular Material Date-Picker is not working properly

I am trying to get date using Angular Material datepicker as mentioned bellow,

In html

<mat-form-field>
<mat-label>Custom calendar color</mat-label>
<input matInput [matDatepicker]="picker2">
<mat-datepicker-toggle matSuffix [for]="picker2"></mat-datepicker-toggle>
<mat-datepicker #picker2 color="primary"></mat-datepicker>
</mat-form-field>

In app.module.ts

import { MatDatepickerModule } from '@angular/material/datepicker';
import { MatNativeDateModule } from '@angular/material';

imports: [
  MatDatepickerModule,
  MatNativeDateModule
],

In my package.json

"dependencies": {
"@angular/animations": "^8.2.9",
"@angular/cdk": "^8.2.3",
"@angular/core": "~8.2.0",
"@angular/material": "^8.2.3",
"@angular/router": "~8.2.0",
"angular-mat-datepicker": "0.0.2",
"angular-material-datepicker": "^1.0.2",
"hammerjs": "^2.0.8",
"ng-material-datetimepicker": "^1.19.2",
},

But the date picker icon is not working, even icon is not showing in the view. I have updated Angular material version as well but that didn't work. What is the solution for this problem?
