It looks like this pull request may not have tests. Please make sure to add tests before merging. If you need an exemption to this rule, contact "@test-exemption-reviewer" in the #hackers channel in Chat (don't just cc them here, they won't see it! Use Discord!). If you are not sure if you need tests, consider this rule of thumb: the purpose of a test is to make sure someone doesn't accidentally revert the fix. Ask yourself, is there anything in your PR that you feel it is important we not accidentally revert back to how it was before your fix? Reviewers: Read the Tree Hygiene page and make sure this patch meets those guidelines before LGTMing. |

It's because of the #include "flutter/runtime/dart_service_isolate.h"
ERROR at //flutter/shell/platform/darwin/ios/framework/Source/FlutterDartVMServicePublisher.mm:45:11: Can't include this header from here.
#include "flutter/runtime/dart_service_isolate.h"
^-------------------------------------
The target:
//flutter/shell/platform/darwin/ios:flutter_framework_source_arc
is including a file from the target:
//flutter/runtime:runtime
It's usually best to depend directly on the destination target.
In some cases, the destination target is considered a subcomponent
of an intermediate target. In this case, the intermediate target
should depend publicly on the destination to forward the ability
to include headers.
Dependency chain (there may also be others):
//flutter/shell/platform/darwin/ios:flutter_framework_source_arc -->
//flutter/shell/platform/darwin/ios:flutter_framework_source --[private]-->
//flutter/runtime:runtime

Nit: I thought from the last discussion that we were moving toward not putting strong?

You're right, I just saw a stray retain and didn't think about it. Removing.

I'm surprised we aren't getting a warning here; this is violating the repeated-use-of-weak-self that Xcode usually warns on. The strongly preferred pattern is to have the first statement be a strongSelf = weakSelf, and then have all the instances be strongSelf, so that it's impossible to have self become nil part way through the method.
