title: How do you add custom text to an SMS in flutter?
body: <p>I'm trying to send an SMS from my flutter app when a user wants to interact with another user. I already have the phone number and I know I can open the SMS window using <em>url_launcher</em> package but that package doesn't let me add my own custom message to it. <strong>I do not want the text to be automatically sent though.</strong></p>
  
  <p>Basically what I want is when the <em>url_launcher</em> launches the SMS window, there is already a custom message that I have provided, so that the user can add on or remove stuff if they want to and <em>then</em> send the text themselves.</p>
  
  <p>Thanks a lot! </p>
