The engine now provides the keyboard and raw keyboard services via the view
services. This patch updates the framework to look there for the keyboard.
Also, this patch migrates callers to the new MojoServices name for these entry
points.
Previously, we would show 4 progress bars, which made it very unclear
what was going on since we'd just said "downloading engine". Now each
separate thing we download has its own announcement.
Eventually we should probably only download Dart, then do the rest of
this inside the flutter tool, as necessary.
Rather than managing all the Material Design icons manually, we now
manage them using an icon font. The icon font contains glyphs for each
icon in an efficient vector format.
This patch updates the FLX tooling to include the MaterialIcons font and
updates the Icon widget to use the font instead of asset images.

Pulls in the following changed required for iOS:
* Application identifiers are legal UTIs.
* Dart precompiled dylib is not a candidate for dead code stripping.
* Account for relative paths on readlink in SnapshotterInvoke
Downloading these packages from cloud storage simplifies our deployment
story because we can upload to cloud storage automatically from the
buildbot.
This patch also switches the responsibility for downloading the engine
artifacts to update_engine.sh. Centralizing this responsibility ensures
that the packages and the binaries are always in sync.
This patch teaches the flutter command to download the Dart SDK into
cache, removing another step from the Getting Started workflow. The
version of the Dart SDK is controlled by the "dart-sdk.version" file in
the bin/cache directory.
Fixes#54
This check is triggering even for folks who don't have FLUTTER_DEV set, which
is breaking their toolchain because we're not running `pub get` on the
flutter_tools package.
Other changes in this patch:
- Make the 'flutter' tool say "Updating flutter tool..." when it calls
pub get, to avoid confusion about what the pub get output is about.
- Make the bash flutter tool call pub get when the revision has
changed. (This was already happening on Windows.)
- Fix a raft of bugs found by the analyzer.
- Fix some style nits in various bits of code that happened to be near
things the analyzer noticed.
- Remove the logic in "flutter test" that would run "pub get", since
upon further reflexion it was determined it didn't work anyway.
We'll probably have to add better diagnostics here and say to run the
updater script.
- Remove the native velocity tracker script, since it was testing code
that has since been removed.
Notes on ignored warnings:
- We ignore warnings in any packages that are not in the Flutter repo or
in the author's current directory.
- We ignore various irrelevant Strong Mode warnings. We still enable
strong mode because even though it's not really relevant to our needs,
it does (more or less accidentally) catch a few things that are
helpful to us.
- We allow CONSTANTS_LIKE_THIS, since we get some of those from other
platforms that we are copying for sanity and consistency.
- We allow one-member abstract classes since we have a number of them
where it's perfectly reasonable.
- We unfortunately still ignore warnings in mojom.dart autogenerated
files. We should really fix those but that's a separate patch.
- We verify the actual source file when we see the 'Name non-constant
identifiers using lowerCamelCase.' lint, to allow one-letter variables
that use capital letters (e.g. for physics expressions) and to allow
multiple-underscore variable names.
- We ignore all errors on lines that contain the following magic
incantation and a "#" character:
// analyzer doesn't like constructor tear-offs
- For all remaining errors, if the line contains a comment of the form
// analyzer says "..."
...then we ignore any errors that have that "..." string in them.
