This patch reorganises flutter_driver's lib/src directory into three
subdirectories:
* driver: sources transitively imported/exported by flutter_driver.dart,
which defines the API used by driver tests executed on the host machine.
* extension: sources transitively imported/exported by
driver_extension.dart, which defines the API used to instrument a
Flutter app running on the target device for use with a driver test.
* common: sources common to both driver and extension code.
This makes rolling Flutter into repositories that use Bazel (or
Bazel-like build systems) significantly more robust, due to the simpler
glob patterns involved.
Declares a top-level getter that returns the outputs directory to which
Flutter Driver tests can write any output files. Timeline data defaults
to this directory.
This commit contains:
- FlutterDriver API for e2e tests usable in conjunction with package:test
- FlutterDriverExtension to be enabled by the application in order to
allow an external agent to connect to it and drive user interactions and
probe into the element tree
- initial implementations of tap, findByValueKey and getText commands (to
be expanded in future PRs)
