title: How to remove the autocompletion of email in the TextFormField when i type characters such as "." or "@"?
body: <p>I created input fields using the TextFormField widget. When i type email that has already been used before, the field just enters the email along with the typed part. This happens when i type characters such as "." or "@". For eg:
  Consider an email : "abcd.efgh@abcd.com".
  When i type "abcd." the field adds the email again as "abcd.abcd.efgh@". </p>
