title: How do I add copy action on a flutter textfield
body: <p>I'm trying to reproduce an application written in java on Android, using Flutter.</p>
  
  <p>The thing I am stuck on is how to allow the user to copy from a read only TextField. Sadly I cannot find an answer in google.</p>
  
  <p>In the old android app, the user inputs some criteria, the input is processed, and results output in a read only text field. If the user presses down on the read only text field, a copy/share context menu pops up, along with text anchors to mark the selection they want to copy. Standard stuff.</p>
  
  <p>I have reproduced the rest of the application, up to the point of outputting the result in a read only TextField. But I just cannot work out how to implement the text anchor copy functionality.</p>
  
  <p>I could really do with some pointers where to look for the solution.</p>
