This works properly for me:

<input type="checkbox" (change)="onChecked($event)">

onChecked (e: Event) {
  const checkbox = e.target as HTMLInputElement;

  if (checkbox.checked) {
    // do something
  }
}

try this: ツ

<mat-checkbox (change)="check($event)"></mat-checkbox>
check(event) {
     console.log(event.checked) // true or false
}
