Date validation using angular material date picker
I am trying to validate dates using the material date picker. Specifically what I am trying to validate is when the user types 'abc' into a date field I would like to show them 'please enter a valid date'. I would like to be able to do that on keystrokes so when they enter 'a' and 'ab' and 'abc' they get the same error.
The problem is the date picker appears to not set the model value and its errors until the value is able to parse to a date. I know this because the form control is not dirty and it still has an error of required when typing 'abc'.
Can this be done?

You can attach a handler on 'dateChange' which is triggered onChange of the input field of the mat-datepicker and validate the user input.
You can also try out 'dateInput' of mat-datepicker.
Refer https://material.angular.io/components/datepicker/api#MatDatepickerInput
Update
HTML
<input matInput [matDatepicker]="picker" placeholder="Input & change events"
(dateInput)="addEvent('input', $event)" (dateChange)="addEvent('change', $event)" (keyup)="keyEvent('keyUp', $event)">
TS
import {Component} from '@angular/core';
import {MatDatepickerInputEvent} from '@angular/material/datepicker';
/** @title Datepicker input and change events */
@Component({
selector: 'datepicker-events-example',
templateUrl: 'datepicker-events-example.html',
styleUrls: ['datepicker-events-example.css'],
})
export class DatepickerEventsExample {
events: string = ;
addEvent(type: string, event: MatDatepickerInputEvent<Date>) {
this.events.push(`${type}: ${event.value}`);
}
keyEvent(type: string, event: KeyboardEvent) {
this.events.push(`${type}: ${event.target.value}`);
}
}

I saw that but unfortunately that is only called when the user tabs out of the field?

Here is a stack blitz. Unfortunately dateInput and dateChange only fire when it thinks it can parse a date. stackblitz.com/angular/…

Thanks. The keyUp event works. It ends up being clunky for us because we have a generic page validation that only triggers when a) field is dirty or b) user presses save. In this case the field is not dirty because it cannot parse. I can bypass this with boilerplate code but it starts getting ugly based on the number of places used.
