 Our code of conduct is much, much stricter than most. We do not wait until someone has been actively rude or insulting. Being disrespectful in any way is grounds for action. For example, passive-aggressive whining and general unconstructive negativity are all violations of the code of conduct. If someone is in a bad mood, we would rather they avoided contributing to Flutter on that day.
 
 When you see something that might be described as unwelcoming or is in some other way a violation of our code of conduct, promptly contact the offender and ask them to read the code of conduct and consider how they might more effectively espouse its philosophy. Most people react very positively to this.

 In the specific case of exposing a value from `dart:ui` via a callback, we expect the bindings in the framework to register a single listener and then provide a mechanism to fan the notification to multiple listeners.

-If anyone would be interested in implementing an official homebrew installation path, the best thing to do would be to reach out on the #hackers-releases channel of our Discord (see [[Chat]]). Implementing it would require integrating into our release pipeline, so familiarity with that would be extremely helpful.

 ## [Design a new vector file format](https://github.com/flutter/flutter/issues/1831) (#1831)
 
 A [design document](https://flutter.dev/go/vector-graphics) containing both a detailed study of the problem and a strawman proposal have been published (comments welcome). The primary goal of the strawman proposal is to see if it is possible to create a format that is implemented entirely on the GPU (the thought being that creating yet another CPU-bound format doesn't really bring the industry forward). The next step is to experiment with implementing the proposal. Unfortunately all our shader experts are currently busy on higher-priority problems (like improving rendering performance and reducing jank), so this work has stalled.

 Golden file tests for `package:flutter` use [Flutter Gold](https://flutter-gold.skia.org/?query=source_type%3Dflutter) for baseline and version management of golden files. This allows for golden file testing on Linux, Windows, MacOS and Web, which accounts for the occasional subtle rendering differences between these platforms.

 If the Flutter build is broken due to a golden file test failure, this typically means an image change has landed without being triaged. Golden file images should be triaged in pre-submit before a change lands (as described in the steps below).
