Angular Material 2 DatePicker, change display format dynamically

Question

I'm using Angular 2 Material's DatePicker component here, and I want to be able to dynamically set the display format of (i.e. YYYY-MM-DD or DD-MM-YYYY, etc.)

There seems to be a way to extend this globally by overriding the used "Date Adapter", but that doesn't work for me because I potentially need different date time pickers to have different formats. I can't set it globally. Is there any known workaround for this?

You can create another input which will display formated date value. In your html create one input for ngModel and matDatepicker, and another one to display formatted date value.

<div style="position: relative">
  <!-- display formatted value -->
  <mat-form-field>
    <input
      matInput
      [value]="currentDate | dateFilter: dateFormat"
      [placeholder]="label"
      autocomplete="off"
    />

    <!--shadow input keep ngModel value-->
    <input
      [matDatepicker]="picker"
      [(ngModel)]="value"
      class="shadow-dateInput"
    />
    <mat-datepicker-toggle matSuffix [for]="picker"></mat-datepicker-toggle>
    <mat-datepicker #picker></mat-datepicker>
  </mat-form-field>
</div>

Here is a working example on Stackblitz
