Android Studio – Flutter Error Undefined class 'RenderContext'

I am having trouble running a Flutter project that was previously working fine with a different person. Specifically, I am encountering an error related to the RenderContext class. The error message I am seeing is: ‘Undefined class ‘RenderContext’ (undefined_class at [path to my file]:[line number]).’

I am using IntelliJ as my environment for this project, and this is my first time using IntelliJ with Flutter. I have tried to use Android Studio to solve this problem.

However, I am still encountering the same error message related to RenderContext. I suspect that there may be a configuration or setup step in IntelliJ that I may have missed.

Can you please offer any suggestions or guidance on how to resolve this issue and get my project running again in IntelliJ? Thank you for your assistance!
