Fail to compile

[fuzeto]

I'm starting with flutter. I followed the walkthrough at https://flutter.dev/docs/get-started/install/linux and I was able to compile 'Hello World'. But when I downloaded the repository from you, I made the dependencies update and clicked compile, it returned the error of the image.

I searched for hours about the error but found no solution.
