title: Is it not valid now the 'authenticateWithBiometrics' in local-auth plugin?
body: <p>I'm using the plugin 'local-auth'. I got the source code that opens a dialog for fingerpring authentication. the method name is 'authenticateWithBiometrics' but it occures an error like this. =&gt; The method 'authenticateWithBiometrics' isn't defined for the type 'LocalAuthentication'.</p>
  <p>Is there a replaceable method in the plug-in? then, please let me know. Thanks.</p>
  <pre><code>authenticated = await _localAuthentication.authenticateWithBiometrics(...)
  </code></pre>
