ConcurrentModificationError in RunOnceViewManager._flushAll()

[izaera]

The method starts with code:

for (final View view in _views) {
if (_ignoreDetached && !view.inDocument) {
_views.remove(view); //ignore detached
continue;
}
...

So, when the if is triggered, a child is removed from _views and thus the for-each throws the error.

I will try to submit a pull request if I have time. I suggest just making a copy of the set before iterating (possible optimization: if _ignoreDetached==false and _ignoreSubviews==false no copy is needed).

Thanks for your reporting.
