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",
            "task_name":"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",
            "task_name":"zzz",
            "flaky":false
        }
    ]
}

• name: (str), builder name
• repo: (str), name of the repository that this task runs against
• task_name: (str), task name that will appear in the flutter build dashboard
• flaky: (bool), if true, failure of this task will not close the tree

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.
