backgroundImage in CircleAvatar issue

CircleAvatar(
        radius: 30,
        backgroundImage: fromAsset
            ? AssetImage(pic ?? '')
            : CachedNetworkImageProvider(pic ?? ''),
      ),

In this sampel code I have this error:
The argument type ‘Object’ can’t be assigned to the parameter type

fromAsset : a boolian that specifies if should return circle with asset or network in this widget.

>Solution :

It can be solved this way:

CircleAvatar(
   radius: 30,
   backgroundImage: fromAsset
      ? AssetImage(pic ?? '')
      : CachedNetworkImageProvider(pic ?? '') as ImageProvider,
),
