<p dir="auto"><strong>Current behavior</strong></p>

<p dir="auto">Angular API reference states that there is only a <code class="notranslate">required</code> ValidatorFn in the class <code class="notranslate">Validators</code> but source code defines required, requiredTrue, compose, composeAsync, email and null.</p>
