title: is there a way to select the default keyboard language in flutter?
body: <p>I want to show a keyboard in English and disable the ability to change the language, is there a way to do so ?</p>
  <p>I'm basically trying to show a keyboard for the user to enter an OTP in English only.</p>
  <p>I have added this to <code>inputFormatters</code> in the <code>TextField</code> :</p>
  <pre><code>                WhitelistingTextInputFormatter.digitsOnly,
  </code></pre>
  <p>and that does not accept ١٢٣... it accepts 123.. which is intended behaviour but the issue is when a user has arabic keyboard.</p>
