onPressed: () => selectImage(context, userId: loggedInUser.uid),

CodePudding user response：

In your selectImage function, if you defined it like this:

selectImage(BuildContext context, String userId) {
//....etc

then when you call the method, it should look like this:

onPressed: () => selectImage(context, loggedInUser.uid),

Because you are using positional parameters, not named parameters.

If you want to use named, change it to this:

selectImage({required BuildContext context, required String userId}) {
//....etc
onPressed: () => selectImage(context: context, userId: loggedInUser.uid),
