How to add File to Array (List)

I got an image from ImagePicker

var image = await ImagePicker.pickImage(source: imageSource);

_images are declared by followed

 List<File> _images = List<File>();

I tried as Follows

_images = image as List<File>

But I got errors like this

Unhandled Exception: type '_File' is not a subtype of type 'List' in type cast

imagepicker.pickimage flutter deprecated. – Mahi Feb 11 '21 at 07:42 — Mahi, Feb 11 '21 at 07:42

You're getting the error because Future<File> pickImage(..) returns File not List<File>.

In you code you're trying to cast File as List<File>:

_images = image as List<File>

If you only want to store the File returned from Future<File>pickImage(..), then you can add the File to the List

_images.add(image);

Also Future<File>pickedImage(..) method is deprecated so please try using Future<PickedFile> getImage(..), which returns PickedFile instead of File.
