Empty List of String appears null when initialized

I am trying to insert a string into my list of strings.

I initialize my string like so in a class called globals that holds this list.

List<String> myStringList = [];

Then in my controller class I am trying to insert a string into the list like so.

globals.myStringList.add(stringToAdd);

But I get an error that says the list is null. Not sure if I am initializing it wrong since it appears this is the way to initialize an empty list.

Globals Class

import 'package:flutter_project/models/categories.dart';
import 'package:flutter_project/models/videos.dart';
List<String> reports = [];
List<Video> videos = [];
List<Category> categories = [];
List<String> userSearches = <String>[];
bool inSearch = false;

Make the variable static so that it can be accessible by the class name

Found the answer, I was initializing my string incorrectly. It has to be done like so.

List<String> myStringList = <String>[];
