This directory contains resources that the Flutter team uses during the development of engine. ## Luci builder file `try_builders.json` and `prod_builders.json` contains the supported luci try/prod builders for engine. It follows format: ```json { "builders":[ { "name":"yyy", "repo":"engine", "enabled":true } ] } ``` for `try_builders.json`, and follows format: ```json { "builders":[ { "name":"yyy", "repo":"engine" } ] } ``` for `prod_builders.json`. `try_builders.json` will be mainly used in [`flutter/cocoon`](https://github.com/flutter/cocoon) to trigger/update pre-submit engine luci tasks, whereas `prod_builders.json` will be mainly used in `flutter/cocoon` to push luci task statuses to GitHub.
