* Clean up some flutter_tools tests
* Remove arbitrary retry that happens even for fundamental errors, and generally clean up _DevFSHttpWriter.
* Update dependencies (requires fixes; see next commit)
* Fixes for new dependencies.
This adds a keycode generator that incorporates input from the Chromium and Android source trees, as well as some local tables, to generate static constants for the LogicalKeyboardKey and PhysicalKeyboardKey classes, as well as mappings from each of the platforms we support so far (currently only Android and Fuchsia).
This code generator parses the input files, generates an intermediate data structure (`key_data.json`) that is checked in, and then generates the Dart sources for these classes and some static maps that will also be checked in (but are not included in this PR).
The idea is that these codes don't change often, and so we don't need to generate them on every build, but we would like to be able to update them easily in the future if new data becomes available. If the existing data disappears or becomes unusable, we can maintain the checked-in data structure by hand if necessary, and still be able to generate the code.
This PR only contains the code generator, not the classes themselves. In another follow-on PR, I'll run the generator and check in the output of the generator.
* Revert "Add dashing config file for generating docset from flutter docs (#24374)"

* Revert "Update driver script to execute test through test_core (#24168)"
This reverts commit 6c62cf337fb662684bb206e89018792eb68eb10a.
* Move integration tests to use vm_service_lib
* Turn off debug logging that was accidentally committed
* Run update-packages --force to fix checksum for new dev dependency
* Trim trailing whitespace
Coverage 0.12.3 includes a fix for dart-lang/coverage#194, which was
causing errors on the flutter build bots.
Linter was updated automatically as a side effect of running
`flutter update-packages --force-upgrade`.
Adds a Fuchsia compatibility function that allows for connecting to a
specific Isolate by name when running Flutter Driver on a Fuchsia
device. This will check over multiple Dart VM's in an attempt to find
an Isolate by its name.
