This changes the packaging tool to only set the remote URL instead of recreating the remote.
Recreating it was removing some metadata that identified the repo as having been cloned from the "real" repo, so flutter --version would report an unknown channel and source. This just sets the URL so that it looks like it came from GitHub.
I also fixed some incorrect comments, and made unzip work on platforms other than Windows (even though we don't really need it there yet).
Fixes#15518
* Roll engine to b6df7a637498ca9beda1fa9cd7210e3202ea599f.

* Update the following packages
- dart-petitparser to 1.7.5
- dart-xml to 3.0.3
- image to 1.1.30
These updates fix some of the strong mode errors we were encountering
while running flutter tests.
This fixes the error handling for the packaging script so that it will properly report a failure exit code when it can't find the executable that it's looking for.
Added a test too.
* 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
* Fix some of the generic types specified to avoid runtime errors in
--preview-dart-2
type 'YamlMap' is not a subtype of type 'Map<String, dynamic>' where
YamlMap is from package:yaml/src/yaml_node.dart
Map is from dart:core
String is from dart:core
package:flutter_devicelab/framework/manifest.dart 17:36 loadTaskManifest
test/manifest_test.dart 14:33 main.<fn>.<fn>
package:test/src/backend/declarer.dart 161:27 Declarer.test.<fn>.<fn>.<fn>
* Add dynamic generic types to keep the analyer happy.
* Address code review comment.
* 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
Dart is migrating to .dart_tool/ as the location for cached artifacts
and other temporary files generated by tooling in the SDK. As part of
this, pub will be migrating from .pub to .dart_tool/pub.
In future, this path will also be used for other tooling, such as package:build.
We can't use .tar.xz on Mac because although it can unpack them on the command line (with tar), the "Archive Utility" that runs when you double-click on them just does some crazy behavior (it
converts it to a compressed cpio archive, and when you double-click on that, it converts it back to .tar.xz, without ever unpacking it!)
So, this changes the script to use .zip for Mac, and the files are about 220MB larger than they need to be.
30+4 has made some changes to the remoting protocol that are incompatbile
with a test harness running 30+3 (e.g. adding a type='initial' field to the
first message)
* Use engine-built dart sdk
* Download dart-sdk from engine
* Move up deps to fix dart sdk constraint problem
* Update update_dart_sdk.ps1 for Windows
* Fix tests so they pass analysis
* More types for tests
* Roll engine
* Update dart sdk stamp location in flutter.bat
* Add newline
This sets things up so that when we next roll a dev build to beta, it updates the docs.
This means that for a while (until we publish a beta) the dev docs will not be updating.
