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

CodePudding user response：

Use null check operator on selectedFile.path as it could be null at run time.

CodePudding user response：

You need to cast the selectedFile null variable to a non-null form of it.

You do that by adding the exclamation mark(!) as a post fix to the null variable.

Solution:

Change this:

File file = File(selectedFile.path)

to this;

File file = File(selectedFile!.path)

Note:

This could fail at runtime if selectedFile is actually null.

You can mitigate this issue by checking if the value is null like this:

if (selectedFile != null) { 
  File file = File(selectedFile!.path)
  //Other operations
} else {
  print('selectedFile is null');
}
