MatNativeDateModule, MatMomentDateModule not found in angular 9.1.1

 Old angular/material has those two modules. but angular/material 9.1.1 version has not those two module. I got below error. Anyone has any idea how to import those two module

Uncaught (in promise): Error: MatDatepicker: No provider found for DateAdapter. You must import one of the following modules at your application root: MatNativeDateModule, MatMomentDateModule, or provide a custom implementation.

Ans:

Angullar 8,9

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

Angular 7 and below

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

You need to import both MatDatepickerModule and MatNativeDateModule under imports and add MatDatepickerModule under providers

imports: [
    MatDatepickerModule,
    MatNativeDateModule 
  ],
  providers: [  
    MatDatepickerModule,
    MatNativeDateModule  
  ],
