In preparation for the merge of flutter/plugins into flutter/packaegs,
update the cross-repo analysis to flutter/packages rather than
flutter/plugins.
The flutter_plugins.version file is left intentionally for now to avoid
issues with the roller; it will be removed when the roller has been
updated to roll the other repository.
In order for this to take effect, https://skia-review.googlesource.com/c/buildbot/+/167200
needs to be landed and deployed.
The /bin/internal/engine.merge_method file controls how we merge a pull
request created by the engine auto-roller. If it's squash, there's only one
commit for a pull request no matter how many engine commits there are inside
that pull request. If it's rebase, the number of commits in the framework is
equal to the number of engine commits in the pull request. The latter method is
easier to detect regressions but cost more test resources.
* Support 'be' channel so you can download dart-sdk from the tip.
This is triggered when you put 'hash/<build hash>' into dart-sdk.version file. For example, 'hash/c0617d20158955d99d6447036237fe2639ba088c'
* Add README.md
* Fix grammar, spacing, 80 chars, nicer ===
