Validation message not showing on input type

Dec 14 2021 3:41 AM

I can’t get a validation message to show on an input type. I’m using for validator.pattern with Form Group and not sure why it will not show. The mat-error tag will not show. I’m looking for help with a possible solution to this for anything over two decimal places. If someone could help me with this I would appreciate.


<div class="col-md-3 offset-md-1">
        <mat-form-field appearance="legacy" floatLabel="always">
          <input matInput type="number" class="example-right-align" placeholder="0" 
      formControlName="bfastAmount" />
          <span matPrefix>$&nbsp;</span>
          <mat-error *ngIf="form.controls['bfastAmount'].errors?.pattern" class="text- 
      danger">Please provide a valid amount.</mat-error>


form: FormGroup = new FormGroup({
bfastAmount: new FormControl('', [Validators.pattern('^\\d{1,2}\\.\\d{2}$')]),
