* Revert "Add dashing config file for generating docset from flutter docs (#24374)"
This reverts commit ec8ca8606c9eec8b1ecc965f5045fd29130a7e16.
* Revert "Update driver script to execute test through test_core (#24168)"
This reverts commit 6c62cf337fb662684bb206e89018792eb68eb10a.
* Fix TODO syntax.
* Clarify messages for some timeouts, to aid debugging.
* Increase some other timeouts that were a needlessly short, to reduce sources of flakes.
* Remove some more timeouts that were mostly redundant, to remove complexity.
* Minor style cleanup.
* Remove some dangerous traps (specifically, hide the explicit start/end times in TimedEvent since they shouldn't matter).
All temporary directory start with `flutter_` and have their random component separated from the name by a period, as in `flutter_test_bundle.YFYQMY`.
I've tried to find some of the places where we didn't cleanly delete temporary directories, too. This greatly reduces, though it does not entirely eliminate, the directories we leave behind when running tests, especially `flutter_tools` tests.
While I was at it I standardized on `tempDir` as the variable name for temporary directories, since it was the most common, removing occurrences of `temp` and `tmp`, among others.
Also I factored out some common code that used to catch exceptions that happen on Windows, and made more places use that pattern.
* Refactor analysis benchmark and collect more data (#20169)
This does some code cleanup to avoid duplication, improves the logs,
and records min and max values as well as the mean.
* Fix typo that led to infinite loop
* Revert "increase size of user account drawer headers to 48 by 48 (#20266)"
This reverts commit 4a7b4a4dde26af64e949388fe8e06d37337ed887.
* Revert "EditableText Cursor can be set to not blink for testing (#20004)"
This reverts commit d041b319e8bda5d02b4d83197eecd3f4ff8a97cf.
* Revert "Refactor analysis benchmark and collect more data (#20169)"
This reverts commit 5ea0a13598697df94937f691783a16b42535b47e.
* Revert "Revert "Roll engine to fed2ea458ed49088d33eddabc546ba56d600c717 (includes dart roll) (#19044)" (#19276)"
This reverts commit cf932490b77c95841e8798e4864ac3e473a79e18 as it also
includes fix for type error that broke tests.
* Add type cast for dart2 type checks.
* Move up to latest goldens
* Make inDirectory() type-parameterized.
* Add typecasting to transitions_perf_test.dart and microbenchmarks.
* Add boolean flag initialization in save_catalog_screenshots.dart
* Add type conversion to gallery transition test
This should make it more obvious from the error what's gone wrong if we see a repeat of #19096 (previously the error was something like "Bad state: future already completed").
