[Hixie]

Wow, how is that possible.

[apwilson]

I think I may have had two or more widgets in a block that had the same key.

[Hixie]

We should assert about that much earlier in that case...

[sigurdm]

I think I hit this one too. Here is a short reproduction:

import 'package:flutter/material.dart';

void main() {
  runApp(new ScrollableList(
    itemExtent: 218.0,
    children: [new Text("A"), new Text("B")],
  ));
}

Run this on a nexus 5x starting in portrait.
Rotate to landscape.
Scroll to the bottom.
Rotate back to portrait.

I/flutter : While the widget tree was being built, laid out, and painted, a new frame was scheduled to rebuild

@sigurdm your case is actually #6063 (note the different stack traces).
