* Roll Dart to 1.23.0-dev.11.3.
This is expected to fix the Windows crashes reported in https://github.com/flutter/flutter/issues/8912.
* fix tests
* Roll to 1.23.0-dev.11.5
* Fix tests
* 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.
Breaking change: removed deprecated methods of PlatformMessages, leaving only binary messaging there. All other use of platform communication now goes through PlatformMessageChannel and PlatformMethodChannels. Retained use of String and JSON codecs for now.
Companion engine PR: flutter/engine#3482
The problem has been fixed upstream in the Dart VM.
This simplifies our setup instructions on Windows (will update the wiki).
Furthermore, this also means that going forward there is no diffrence between PowerShell and Cmd for the Flutter experience on Windows.
This should make our scripts compatible with PowerShell 2 or newer. PowerShell 2 was released in October 2009 and shipped with Windows 7 as default. (I suspect the scripts are now also compatible with PowerShell 1, but that's unconfirmed). This fixes#8606.
The PR also introduces better error handling when Flutter fail to download the Dart SDK to fix#8627.
* Enable Hot Reload on Windows (backed by gen_snapshot)
\o/
Two caveats:
* Hot Reload on Windows is slower than on other platforms because gen_snapshot is slower then sky_snapshot
* We currently cannot hot reload projects with spaces in the path
* enable tests
This reverts commit e7bde11cc3a68b27c17ef8b18258cd384d043fb8.
Reason: broke hot reload when using "package:" style imports for sources
within the same project.
* Simplify path handling logic in dependency checker and devFS
Simplification will make it easier to port this to Windows.
* Roll Engine to 0a7b177c330367904597a6129b3eb653d29dfca0
* Roll engine to b64c88766dbd83bf4bab1cd1cd1757139b6cdb74.
Picks up changes to include inlined frames and line numbers in AOT stack traces.
* Adjust/weaken stack_trace_test.dart to pass in the face of async causal stack traces (Issue #8128).
Call `pub upgrade` instead of manually deleting `pubspec.lock` and then calling `pub get`. `pub upgrade` ignores the `pubspec.lock`, but is otherwise identically to 'pub get' (https://www.dartlang.org/tools/pub/cmd/pub-upgrade).
