* 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
* Sync .packages file as regular file.
Currently .packages file is treated specially as DevFSStringContent to accommodate package-file rewrite when it is sent to the device for dart1 compilation. In dart2 we need to treat .packages as regular file because from frontend perspective it's just a normal input file.

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

* [kernel/flutter] Improve speed of first hot reload
Do so by not evicting unnecessary paths (while still evicting paths
that was changed between the generation of the package file and the
initial upload).
* Fix grammar in method name
* Fix bad merge
* Add method to super class
This reverts commit 5e7bcbacf8.
`flutter run --benchmark` was triggering a different quick bailout path in the VM than `flutter run`. The failure has been fixed upstream.
* Fix restart flow for preview-dart-2 mode.
Restart in preview-dart-2 needs to use kernel file and it has to be complete, rather than incremental kernel file.
* Add curly braces
* Do full compile on restart
* Roll engine to pick up changes to hot reload for preview-dart-2
This reverts commit 90028813a8.
This change caused a few bots to fail with 'JSON-RPC error 110: Extension error', which is odd because _getUnusedChangesInLastReload is not an extension.
- [x] Catch SocketErrors and handle them gracefully.
- [x] Print 'Lost connection to device' when the service protocol connection is severed unexpectedly.
- [x] Print 'Application finished' when the application exits otherwise.

* [devFS] Use URI to represent paths on device
Previosuly, regular file paths in the format of the host platform were used to represent paths on device. That works when host and device share the same (POSIX) file path format. With a Windows host, this breaks. URIs are the solution as they are platform independent and the VM service on the device already interpreted the file paths as URIs anyways.

* Revert "Revert "Simplify path handling logic in dependency checker and devFS (#8414)" (#8467)"
This reverts commit 96ba7f76d2.
* Intentionally use a self-package URI in flutter_gallery
* tests to catch problems with self-package imports
* Simplify path handling logic in dependency checker and devFS
Simplification will make it easier to port this to Windows.

Refactor DevFS so that it's easier to add new types of content such as kernel code
* add tests for DevFS package scanning
* add tests for DevFS over VMService protocol
* which covers _DevFSHttpWriter and ServiceProtocolDevFSOperations
* replace AssetBundleEntry and DevFSEntry with DevFSContent
* refactor to cleanup common code and replace some fields with locals
* rework .package file generation refactor away DevFSOperations.writeSource
* only update .package file if it has changed
* only write/delete/evict assets that have been changed/removed
Each stack trace will yield many async task stacks for every write request
that is in flight. If the device side is unresponsive and all writes are
failing, then this can generate an overwhelming amount of logs.
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 the old policy the most recent log would not be printed until the next
log is produced (which may be indefinitely). This change prints logs
immediately along with a time delta since the previous log.
* Rollback commits to get iOS into a stable state
This rolls back the following commits:
* 23c52fc (#6434)
* a97cf4b (#6433)
* e72e174 (#6428)
It also updates the engine to a newer revision that has the
necessary rollbacks in the engine repo.
Fixes#6458
This change adds a top-level getBuildDirectory func and funcs for
android, aot, asset, ios build products.
Developers may now add a "build-dir" mapping to their
~/.flutter_settings (JSON format) config file. Output directory is
relative to the main flutter application directory.
This change also changes the default build directory for iOS builds to a
subdirectory of the configured build directory, 'build/ios' by default.
- [x] Refactor view support into separate classes.
- [x] Make the hot runner grab the main view and call runFromSource on it.
- [x] Remove Device.needsDevFS (because it is always true).
- [x] Update engine to bring in new snapshotter.
- [x] Use the new snapshotter to quickly determine the minimal set of files necessary to run.
- [x] On first DevFS sync, only sync files necessary to run the application.
- [x] Fix a DevFS unit test failure.
- [x] Include DevFS tests in all.dart.
* General improvoments to the loader app:
* Show a message after 8 seconds if no connection comes in.
* Show a progress bar as files are being uploaded.
* Hide the spinner just before launching the application.
* General improvements to the "flutter run" UI:
* Add "?" key as a silent alias for "h".
* Make the help text bold so it doesn't get mixed with the logs.
* Make "R" do a cold restart when hot reload is enabled.
* Supporting features and bug fixes:
* Add support for string service extensions.
* Other bug fixes:
* Expose debugDumpRenderTree() outside debug mode.
* Logger.supportsColor was missing a getter.
* Mention in the usage docs that --hot requires --resident.
* Trivial style fixes.
