How to get current cursor position in TextFormField (preferrably using TextEditingController)?

Question

I am trying to implement the 'Tagging users in comments' feature similar to Instagram.

Requirements:

• A list of users should be shown when a user types one or more characters after '@'.
• The term to be queried can be anywhere in the text and not just at the end.
• There can be more than one tagged user.

Found this answer for user-tagging in Flutter, but it shows a suggestion list only if the tag is at the end of the text while typing. It would be great if I could modify this behavior based on the current cursor position in the TextFormField. I looked at the TextEditingController API to find something similar but could not find anything useful.

Is there any way to get such information or am I missing something?

As per your requirements:

• If you want to display the user list after @, You may have to create a Widget that can show as a popup with the list of users. For that, you can check https://stackoverflow.com/a/57846261/1318946
• queried can be anywhere in the text and not just at the end, For that you can use https://pub.dev/packages/rich_text_controller
• For the multiple mentions, Use this one https://pub.dev/packages/flutter_mentions
