I love how this keeps coming up because Graham has closed all the issues. To the point it needs a master issue. He closes some saying "Duplicate" pointing to one he has closed for no reason ffs.

Standard.

It looks like cast checking for isDirty() was added just a few days after @quetzyg commented.

I think this is now implemented?

I'm not sure the current implementation has resolved this issue

In a project I'm currently working on (Laravel 6.2) I've had to implement the following workaround in order for the casting to work in getDirty(), otherwise something I've cast as an array comes through as a string.

'my_field_name' => 'array'

// following method is in a trait implemented by a model
public function getRawDiff()
{
    $changed = $this->getDirty();

   dump($changed['my_field_name']); // dumps a string

    foreach($changed as $key => $value) {
        if ($this->hasCast($key)) {
            $changed[$key] = $this->castAttribute($key, $value);
        }
    }

    dump($changed['my_field_name']); // gives me the array

    //...
}

If I'm reading that PR's implementation correctly, the first dump should return an array?
