Description

FilePicker.PickMultipleAsync() can return null.
The method declaration is Task<IEnumerable<FileResult?>> PickMultipleAsync(PickOptions? options = null);, but it should be Task<IEnumerable<FileResult>?> PickMultipleAsync(PickOptions? options = null);

The IEnumerable should be nullable, not the FileResult.

See issue #27710

Steps to Reproduce

var fileResults = await filePicker.PickMultipleAsync(PickOptions.Default);

// Warning: Expression is always true according to nullable reference types' annotations
if (fileResults is not null)
{
    foreach (var fileResult in fileResults)
    {
        // Dereference of a possibly null reference
        Console.WriteLine(fileResult.FileName);
    }
}
