title: PlatformFile selectedFile Type: PlatformFile The argument type 'String?' can't be assigned to the parameter type 'String'
body: <p>So i was following along a curse on youtube, but he made a list like this 'List selectedFiles = List();' and it gave me an error so i did it like this 'List selectedFiles = [];'
  but now it gives me an error and idk if it is because of that</p>
