Build a code editor with syntax highlighter using TextField in Flutter

I am trying to build Code Editor in Flutter app using TextField, I tried using flutter_syntax_view but the problem is, it only accept code as a predefined string text and it does not have any option to write a code.

This is what I have tried:

• Used TextField with maxLines 10
• If we can show number of lines on left like code editor

Open for suggestions, appreciate the help

See my work on github: http://github.com/icedman/flutter_editor

It uses flutter_highlight, multicursor edits, minimap, line number gutter. Under development - you may want to contribute to that project.

I also wrote an article on creating an editor under 1000 lines of code in Flutter - wherein i explained why i ditched the textfield and made my own widget:
