how to contentResovlver within a Fragment?

Question

contentResolver is Unresolved reference: contentResolver how do I rectify this?

class fragment_edcards_media_animimage : Fragment() {
// TODO: Rename and change types of parameters
private var param1: String? = null
private var param2: String? = null
lateinit var u : FragmentEdcardsMediaAnimimageBinding

// Animated Image
private val getContentCardAnimImage = registerForActivityResult(ActivityResultContracts.GetContent())  { uri: Uri ->

    val contentResolver = contentResolver
    val source = ImageDecoder.createSource( contentResolver, uri )
    val drawable = ImageDecoder.decodeDrawable(source)

    Log.d("EditCards",uri.toString())

    //u.iViewAnimImage.setImageDrawable(drawable)
    if (drawable is AnimatedImageDrawable){
        drawable.start()
        //drawable.repeatCount = 2
    }

    val file = File( uri?.path )
    mydecklist[cCardPosition].c_animimageuri = mytools.getImageFromMediaStore(u.iViewAnimImage.context,file.name)
}

Attempt #1 activity.contentResovlver results in; Only safe (?.) or non-null asserted (!!.) calls are allowed on a nullable receiver of type FragmentActivity?

Attempt #2 val contentResolver = activity?.contentResolver

val source = ImageDecoder.createSource( contentResolver, uri ) Type mismatch: inferred type is ContentResolver? but ContentResolver was expected

I've bolded where it thinks the error is in the line ImageDecoder.

Attempt #3 val contentResolver = getActivity().contentResolver() Expression 'contentResolver' of type 'ContentResolver!' cannot be invoked as a function. The function 'invoke()' is not found

And

Only safe (?.) or non-null asserted (!!.) calls are allowed on a nullable receiver of type FragmentActivity?

This appears to be the answer; val contentResolver = requireActivity().contentResolver
