body: <p>How to change biometric authentication <strong>failed messages</strong>. I used flutter <a href="https://pub.dev/packages/local_auth" rel="nofollow noreferrer">local_auth</a> package.<br>
  I want to translate messages below to another language. I think these messages are coming from system and using system language. It must be in english even system language is in another language. In my case, title's text is in English, body's texts are in French. It must be in same language.<br>

  - Keep your finger on the sensor a little longer.<br>
