title: Restrict all kinds of emojis in Text Field in flutter
body: <p>I am looking for a way using which there should be <strong>no emoji character allowed</strong> in the <strong><code>textfield</code></strong></p>
  
  <p>or else a way to find out if there is a emoji  present in a string or not  <strong>[regex]</strong></p>
  
  <p>any one way of it could workout.</p>
  
  <p>I have gone through all the related questions and their solutions but they don't cover the entire use cases.</p>
