LGTM overall, left some comments.

+  if (!views_to_recomposite_.empty()) {
+    return true;
+  }
+  if (active_composition_order_.size() != composition_order_.size()) {


nit: can we just simply compare if (active_composition_order_ != composition_order_) return true; I might be missing something in c++

cyanglaz · 2019-07-03T00:39:15Z

flow/embedded_views.h

 public:
  ExternalViewEmbedder() = default;

+  virtual bool HaveEmbeddedViewsMutated() = 0;


nit: maybe name it EmbeddedViewsWillMutateAtTheCurrentFrame? Since this method has to be called before the mutation actually happens at the same frame, we probably want to to have the name indicate that. This method is not going to give the desired result if called after CompositeEmbeddedView. Although EmbeddedViewsWillMutateAtTheCurrentFrame is too wordy.
I'm not good with names tho @amirh might have some thoughts.
Also, maybe document it somewhere to explain when the method should be invoked to get the desired result.

Or maybe just EmbeddedViewsWillMutate and document explain the current frame part.

I am not very satisfied with the name. having CurrentFrame is misleading as we could process multiple layer trees in the current frame. I added a comment saying that this needs to be called after pre-roll.

maybe: HasPendingViewOperations?

flow/embedded_views.h

 public:
  ExternalViewEmbedder() = default;

+  // This will return true after pre-roll if any of the embedded views


Doesn't have to be in this PR, but we will need a way to clear active_composition_order_ if we're redoing the frame, maybe by adding something like CancelFrame here?

Yup, will do it as a follow-up PR.
