Event' is not assignable to parameter of type 'MdbCheckboxCh

Expected behavior

No error

Actual behavior

Argument of type 'Event' is not assignable to parameter of type 'MdbCheckboxChange'.

Resources (screenshots, code snippets etc.)

<form [formGroup]="chkForm" id="chkIncludeCount" >  
        <div class="row">

          <div class="col-md-12">
            <div class="form-check">
                <input
                mdbCheckbox
                class="form-check-input"
                type="checkbox"
                value=""
                formControlName="chkIncludeCount"
                (change)="onChkChange($event)"
                />
                <label class="form-check-label" for="flexCheckDefault">
                Include document count
                </label>
            </div>

          </div>
        </div>
      </form>

This shows an error

  onChkChange(event: MdbCheckboxChange): void {

Change to any and I get no error

  onChkChange(event: any): void {

The component includes:

import { MdbCheckboxChange } from 'mdb-angular-ui-kit/checkbox';

Am I missing something?
