Issues Running Cloned Flutter Project on Mac

I started a Flutter project on my Windows PC, but now I want to test it on my Mac. I have installed all the necessary tools, including an emulator. The emulator works fine when I create a new Flutter project and run it, but I encounter an error when I clone the project from my Windows PC to my Mac and try to run it.

Here is a snippet from my debug console:
