"User Interface" example gives Error: Unexpected null value. when debugged on Chrome #268

I'm trying to develop an cross-platform app using flutter maplibre gl, and while I've got it working on Android, debugging using Chrome gives an "Error: Unexpected null value". Using VSCode for debugging, Chrome 114.0.5735.198 on Ubuntu 23.04.

I've noticed that I can replicate the same error in the examples provided in this repository. Open the example folder as a project in VSCode and then debug it using Chrome. The main screen loads fine, but the error occurs when you enter the "User interface" example.

Exception has occurred.
