Error occurred while writing TextEditingController code in Flutter

[jsawdey]

DISCLAIMER: This is my first issue in GitHub, so please let me know if there is any other information that I need to add.

I'm writing a Flutter app using the Redux framework, and I was in the middle of typing when an IntelliJ error popped up, which gave me the prompt to submit this issue to the dart project. I was coding a simple TextEditingController in a StatelessWidget, an IntelliJ error (I'm using Android Studio 3.2.1) popped up.

Here is the line I was typing out (I stopped typing as soon as the error popped up):
final TextEditingController _controller = TextEdi
