title: Flutter - Local_auth (Required security features not enabled)
body: <p>I'm trying to get biometrics authentication to work again after updating the app I'm developing.
  But I'm constantly getting the same error when activating it:</p>
  <pre><code> PlatformException(NotAvailable, Required security features not enabled, null, null)
  </code></pre>
  <p>The current one in the store has no problems at all.</p>
  <p>I'm using local_auth: 1.1.4<br />
  MainActivity.java has been converted to a FragmentedActivity<br />
  I'm doing a simple check to see if the biometrics are available. Which they are</p>
  <pre class="lang-dart prettyprint-override"><code>bool canCheckBiometrics = await auth.canCheckBiometrics;
  List&lt;BiometricType&gt; availableBiometrics =
  await auth.getAvailableBiometrics();
  
  print(canCheckBiometrics); //Returns true
  print(availableBiometrics.toString()); //Returns [BiometricType.fingerprint]
  </code></pre>
  <p>After that I try to do the authentication</p>
  <pre class="lang-dart prettyprint-override"><code>try {
      authenticated = await auth.authenticate(
          biometricOnly: true,
          localizedReason: 'Login with biometrics',
          useErrorDialogs: true,
          stickyAuth: false);
  } on PlatformException catch (e) {
      print(e);
  }
  </code></pre>
  <p>This returns:</p>
  <pre><code>PlatformException(NotAvailable, Required security features not enabled, null, null)
  </code></pre>
  <p>And this is what the plugin comments in the code say.</p>
  <pre><code>// Indicates the device does not have a Touch ID/fingerprint scanner.  
  const String notAvailable = 'NotAvailable';
  </code></pre>
  <p>I'm not really sure what to check anymore. Is this something new I need to be aware of?</p>
  <p>Really hope someone can help me with this issue!</p>
  <p>Hope to hear!</p>
