Solution

  • You can put an ! behind it to indicate you are sure it can't be null, so like

    for (final value in widget.details.data.productPriceObjs!) {

    If you don't like using ! you can alternatively write

    var objects = widget.details.data.productPriceObjs;
if (objects != null) {
  for (final value in objects) {
  
  }
}

    Somehow the compiler is fine with it when there isn't "nesting" in the check
