Splits Xcode validation out of the iOS validator and into a stand-alone
validator, and groups the CocoaPods validator with that top-level
validator instead of the iOS validator. iOS now validates only the
iOS-specific tools (e.g., ideviceinstaller).
Reorganizes many of the associated clases so that those that are used by
both macOS and iOS live in macos/ rather than ios/. Moves some
validators to their own files as part of the restructuring.
This is the macOS portion of #31368
* add trailing commas on list/map/parameters
* add trailing commas on Invocation with nb of arg>1
* add commas for widget containing widgets
* add trailing commas if instantiation contains trailing comma
* revert bad change
## Description
Also update the existing dart files with missing licenses.
Without the fix, we'll emit the following error message

* Upgrade everything except matcher.
* Roll matcher (and test)
* Adjust tests that depend on flutter:test directly to depend on a shim
* Require use of package:test shim and remove other references to package:test
Previously, Flutter did not support iOS devices with armv7 or armv7s
CPUs. We now support these devices. This eliminates the previous
hardcoded checks that prevented running on simulators of older devices.
We maintain the existing restriction on running on watchOS or tvOS
simulators.
* Change async stubbing to use thenAnswer.
Mockito now prohibits calling thenReturn with Futures and Streams. dart-lang/mockito#79
* Update all Mockito deps to 3.0.0.
* Revert "Update all Mockito deps to 3.0.0."
This reverts commit e8ab9d37c3.
I did not correctly update the mockito dep, and there's no easy way to update to 3.0 alpha right now.
* Change thenAnswer((_) => to thenAnswer((invocation) =>
* Add Invocation type to thenAnswer lambdas
Add support for IOS_SIMULATOR_HOME environment variable in IOSSimulator.logFilePath
flutter_tools can be run on environments where the user's HOME directory
is not the root of the iOS simulators' configs. This change adds support
for such environments by allowing the caller to set the simulator root
directory via an environment variable.
1. Migrate simulator device log tailing to os_log toolchain
2. When the log tag (component) is available (iOS 11/Xcode 9), filter to
the set of log lines with tag 'Flutter'.
As of iOS 11 / Xcode 9, Flutter engine logs are no longer recorded in the
simulator's syslog file, which we previously read using tail -f. Instead
they're now accessible through Apple's new macOS/iOS os_log facility,
via /usr/bin/log, which supports a relatively flexible query language.
When run in non-interactive mode, /usr/bin/log buffers its output in 4k
chunks, which is significantly smaller than what's emitted up to the
point where the observatory/diagnostics port information is logged. As a
workaround we force it to run in interactive mode via the script tool.
