This allows test environments other than `flutter test` to have a hook
into the test exception reporting. Some test environments, for example,
don't just dump error details to the console, but rather require them
to be reported to a separate server.
Our style guide says the k's are not necessary, and it seems like a good idea to make all the code be consistent on this.
Only naming changes to private vars: no logic changes.
I'm moving the assets in the assets-for-api-docs repo to a slightly different location to help with organization in that repo, so this PR points the doc URLs to the new location. The old assets won't be removed until this PR makes its way to the API docs website.
No documentation or code changes here, other than changing doc image URLs.
This test fails consistently on mac2 and mac3 with the attached Moto G4
devices but passes consistently on other machines.
Adding a delay of 1s right after driver.connect() in setUpAll() causes
it to pass on the machines in question, which suggests a race condition.
Specifically it looks like connect returns the moment Flutter Driver
identifies that the isolate is up and running, but empirically it looks
like we start running the first test before the UI is actually up. This
triggers a failure wherein we start looking for elements before they're
onstage.

Removes a previous hack that no longer appears to help (adding a 1
second delay in setUpAll() does seem to work around this issue though).
* Exclude flutter_goldens package from dartdoc because it's for internal
use only
* Document why flutter_tools doesn' tneed to be excluded from the list of
packages to document
* Performance optimization in the flutter comparator, and associated
test updates.
In order to avoid checking binaries into flutter/flutter,
this comparator can be used to retrieve golden files from
a sibling flutter/goldens repository.
https://github.com/flutter/flutter/issues/16859
* Configure Cirrus CI
* Read file directly instead of shelling a command
* Wait for all streams to finish
* Add LTR `textDirection`
Since `RenderFlex#_debugHasNecessaryDirections` requires it when `direction` is horizontal and there are multiple children.
* Add a `matchesGoldenFile()` async matcher that will match
a finder's widget's rasterized image against a golden file.
* Add support for pluggable image comparison backends
* Add a default backend that does simplistic PNG byte
comparison on locally stored golden files.
* Add support for `flutter test --update-goldens`, which will
treat the rasterized image bytes produced during the test
as the new golden bytes and update the golden file accordingly
Still TODO:
* Add support for the `flutter_test_config.dart` test config hook
* Utilize `flutter_test_config.dart` in `packages/flutter/test`
to install a backend that retrieves golden files from a dedicated
`flutter/goldens` repo
https://github.com/flutter/flutter/issues/16859
* Turn support for sync-async on in Flutter. With this feature
execution of async functions starts immediately instead of it
being delayed by one microtask tick.
* Address review comments.
* Adjust some stack trace expectations which are slightly different with
--sync-async turned on.
* Handle error count reported by frontend.
Extend compilation result from single string to a structure(string filename and integer error count).
* Use ?.
* Include engine roll with dart sdk roll.
* parse(onError) -> tryParse
* Make '?? throw' more readable and avoid issue with analyzer
* Fix test so it mocks compiler output including errors count
