title: Referencing a flutter file after importing it
body: <p>So I have imported a dart file into my main.dart. Now that I have imported it successfully, I would like to use the code of that file and I am not sure of how I will call the whole dart file I have imported into the main.dart file so that I can use some of the classes in the other file. It is telling me I have unused imports but I do not know how to use the files I have imported. Please help.</p>
