The code from package:flutter_test/src/finders.dart that results in the error:
@override
Iterable<Element> filter(Iterable<Element> parentCandidates) sync* {
for (final Element candidate in parentCandidates) {
final RenderBox box = candidate.renderObject as RenderBox;
assert(box != null);
final Offset absoluteOffset = box.localToGlobal(alignment.alongSize(box.size));
final HitTestResult hitResult = HitTestResult();
WidgetsBinding.instance!.hitTest(hitResult, absoluteOffset);
for (final HitTestEntry entry in hitResult.path) {
if (entry.target == candidate.renderObject) {
yield candidate;
break;
}
}
}
}
As this Widget is a Sliver, it cannot be cast to a RenderBox. I did not work much with Slivers, I am therefore unsure how this is correctly implemented for them. I know that they work with geometry, but I don't know how to get the absoluteOffset for the calculation.
If someone could point me to the right direction, I would create a PR for this
