As per the recent fix to the `always_specify_types` lint (https://github.com/dart-lang/linter/issues/199), literal maps and lists are now expected to be explicitly typed.
Running that lint on the repo identifies quite a few spots to update. This focuses on `flutter_driver` and `flutter_sprites` (somewhat arbitrarily) but the changes are fairly representative.
Note there are a number of places where I made a quick judgement on how specific to make the types. Feedback on those is welcome. (Especially as we move forward with more.)
Bindings now have a debugRegisterServiceExtensions() method that is
invoked in debug mode (only). (Once we have a profile mode, there'll be
a registerProfileServiceExtensions() method that gets called in that
mode only to register extensions that apply then.)
The BindingBase class provides convenience methods for registering
service extensions that do the equivalent of:
```dart
void extension() { ... }
bool extension([bool enabled]) { ... }
double extension([double extension]) { ... }
Map<String, String> extension([Map<String, String> parameters]) { ... }
```
The BindingBase class also itself registers ext.flutter.reassemble,
which it has call a function on the binding called
reassembleApplication().
The Scheduler binding now exposes the preexisting
ext.flutter.timeDilation.
The Renderer binding now exposes the preexisting ext.flutter.debugPaint.
The Renderer binding hooks reassembleApplication to trigger the
rendering tree to be reprocessed (in particular, to fix up the
optimisation closures).
All the logic from rendering/debug.dart about service extensions is
replaced by the above.
I moved basic_types to foundation.
The FlutterWidgets binding hooks reassembleApplication to trigger the
widget tree to be entirely rebuilt.
Flutter Driver now uses ext.flutter.driver instead of
ext.flutter_driver, and is hooked using the same binding mechanism.
Eventually we'll probably move the logic into the Flutter library so
that you just get it without having to invoke a special method first.
The way we pick observatory port # has changed and we have broken
logic that handles port 8181. To fix the buildbot, switch to port
8182. We can later figure out what we want to do when we clean up
port handling.
The old VM extention for extracting the timeline data is gone.
Switch to the new '_getVMTimeline' API.
Runs a test app and a driver test simultaneously, then stops the app.
Usage:
```
flutter drive --target=/path/to/test/app.dart
```
This command will look for `/path/to/test/app_test.dart` by
convention. We will expand into other ways of discovering tests in the
future.
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)
