* 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
* Update dependencies with forced upgrade.
Now that https://github.com/flutter/flutter/issues/15261 is fixed, do the update with upgrade.
* Update test package use following upgrade
* Replace addOption(allowMultiple) with addMultiOption
Make flutter test support the --track-widget-creation flag.
Add widget creation location tests. Tests are skipped when
--track-widget-creation flag is not passed.
* Create frontend compiler in `flutter test` lazily.
This is needed to avoid unwarranted runtime dependencies on Artifacts,
for example when in non-preview-dart-2 mode.
Refactor the compilation-related code into _Compiler class.
* Fix `flutter test --preview-dart-2` following last dart roll.
Incremental compiler maintains single incremental dill file, so for every test compilation that dill file has to be copied away for execution.
* Fix lints
* Add to Artifacts, and add optional arguments to entry points for flut… (#15185)
Add to Artifacts, and add optional arguments to entry points for flutter run and test to allow for wiring up the same with preview-dart-2 internally
* Changing packages uri here is not necessary
* Run flutter tests in preview-dart-2 mode on travis flutter builds.
* Run dart2 tests on osx. Run dart tests in dart2.
* Fix name camelCase
* Default options to empty array, rather than null
* Troubleshoot failures
* More logging
* Troubleshoot: run single test
* Troubleshoot: run 15 tests
* Troubleshoot: run 15 tests with fix
* Try limit concurrency to 1
* Limit concurrency for preview-dart-2 tests to 4
* Move dart2 tests to allow_failures section
* Reinstate tests_dart_2 shard
* Raise concurrency to 8
* Reuse compiler across multiple test runs
* Allow to switch entry points when recompiling.
Actually use single compiler to incrementally recompile all tests executed by 'flutter test'.
* Remove leftover commented code
* Fix comment
* Lints
If compiler failed to produce Kernel binary then compile(...) returns
null to the caller. If we don't check for null we end up trying to
run file called "null" which causes a very confusing crash of the
flutter_tester.
* Default to strong for 'flutter test --preview-dart-2' mode
* Remove empty line
* Dont init to null
* Break up line to make it more readable
* Add missing type annotation
* Bump to Dart SDK 1.23.0-dev.10
* allows us to understand flutter usage via telemetry
* brings in `@immutable`
Fixes: #9042
* completer fix
* Update to platform 1.1.1.
