* roll engine version to 6280adbfb1f9f63cdc6179b9b78634add1e4f2e3
* Correctly handle previewDart : false setting in AnalysisServer and
AnalyzeOnce classes.
This reverts commit e13e7806e3.
Turns out that with this patch, we aren't actually catching all
errors. For example, `flutter analyze --flutter-repo --watch` didn't
report errors in `dev/devicelab/test/adb_test.dart`.
* flutter analyze --watch auto detect if in flutter repo
* move isFlutterLibrary from AnalyzeOnce into AnalyzeBase for use by AnalyzeContinuously
* pass --flutter-repo to analysis server when analyzing the flutter repository
* enhance flutter analyze --watch to summarize public members lacking documentation
* first pass
* improvements
* extract terminal.dart
* rebase
* add default terminal to context
* The analyzer wants the ../ imports in front of the ./ imports
* review notes
This removes direct file access from within flutter_tools
in favor of using `package:file` via a `FileSystem` that's
accessed via the `ApplicationContext`.
This lays the groundwork for us to be able to easily swap
out the underlying file system when running Flutter tools,
which will be used to provide a record/replay file system,
analogous to what we have for process invocations.
With this change, they're run via instance methods on an object
obtained through the context. This will allow us to substitute
that object in tests with replay/record versions to allow us to
mock out the os-layer in tests.
* Remove the workaround that pinned args to v0.13.6
This reverts most of the changes in commit 6331b6c8b5
* throw exception if exit code is not an integer
* rework command infrastructure to throw ToolExit when non-zero exitCode
* convert commands to return Future<Null>
* cleanup remaining commands to use throwToolExit for non-zero exit code
* remove isUnusual exception message
* add type annotations for updated args package
