[dev] Don't use await for on stdout and stdin; pass local engine argument (#72136)
* [dev] Don't use await for on stdout and stdin; pass local engine argument

1) Don't use await for on stdout followd by await for on stderr.
   This can cause nothing to happen. E.g. if one didn't do something
   like `flutter pub upgrade` dev/automated_tests and the version in the
   old one was pre-nnbd (but flutter itself use lots of nnbd stuff) lots
   of errors would be emitted, but because we basically only listen to
   stdout nothing will happen (deadlock once stderr buffer runs out).
   Note that it still awaits the exit-code below.
2) Pass --local-engine (if given) so there won't be any crashes because
   of that.

This directory contains tools and resources that the Flutter team uses during the development of the framework. The tools in this directory should not be necessary for developing Flutter applications, though of course, they may be interesting if you are curious.

The tests in this directory are run in the framework_tests_misc-* shards.

Luci builder file

try_builders.json and prod_builders.json contain the supported luci try/prod builders for flutter.

try_builders.json

It follows format:

{
    "builders":[
        {
            "name":"yyy",
            "repo":"flutter",
            "taskName":"zzz",
            "enabled":true,
            "run_if":["a/b/", "c/d/**"]
        }
    ]
}
  • enabled(optional): true is the default value if unspecified
  • run_if(optional): will always be triggered if unspecified

prod_builders.json

It follows format:

{
    "builders":[
        {
            "name":"yyy",
            "repo":"flutter",
            "taskName":"zzz",
            "flaky":false
        }
    ]
}

try_builders.json will be mainly used in flutter/cocoon to trigger/update pre-submit flutter luci tasks, whereas prod_builders.json will be mainly used in flutter/cocoon to refresh luci task statuses to dashboard.
