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.
Function keys don't work great on any platform we support:
* Mac doesn't have first-class function keys.
* On Ubuntu: F1 opens the system help and F10 opens the file dialog.
* ... and Windows is a mess as well.
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.
* 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.
Also, make it clear the screen between results so it's more obvious
what's going on when you have new results (especially when you have
fixed everything).
* refactor the --resident run option into a separate file
* update daemon to run --resident apps
* re-plumbing daemon start
* send app logs
* update tests
* review changes
* fix test runner
* remove PackageMap.createGlobalInstance; rely on the ctor
* review comments
* more terse flutter upgrade
* fix an issue when updating and the engine update code has changed
* call flutter precache; add a --no-color hidden option
* fix a lint related to getters/setters
