Our test script is getting complicated enough that doing your own
testing with a custom engine has become tedious. Now you can just do:
```bash
(cd ~/dev/flutter/; FLUTTER_TEST_ARGS=--local-engine=host_debug_unopt dev/bots/test.sh)
```
...to run all your tests (assuming your flutter repo is in
`~/dev/flutter` and your engine in `~/dev/engine`).
* MultiTapGestureRecognizer previously would assert if there was no
competition.
* GestureArenaTeam would always select the first recongizer as the
winner even if a later recognizer actually accepted the pointer
sequence.
* debugPrintStack would fail a type check if maxFrames was non-null.
* FractionalOffset.lerp would throw a null-pointer exception if its
second argument was null.
Also, add a number of tests for previously untested lines of code.
This is handy for debugging a test. Communication is logged to:
* `flutter_driver_commands_{x}.log`, where {x} is an integer, and
* (if requested by user) to stdout
fixes#7473
The demo of the SimpleDialog had some useful code that should really be part of
the framework. This patch extracts it into a SimpleDialogOption widget.
Remove debugCheckHasScaffold because it is unused.
Also, add tests for InkWell, SimpleDialog, and other widgets.
Previously, the Slider used a drag gesture recognizer to move the head
of the slider, but when the slider was in a vertical scroller, the
recognizer would wait until the user moved the pointer by enough pixels
to disambiguate between sliding the slider and scrolling the scroller.
That worked fine for actual drags, but the slider should also move when
the user taps the track. This patch introduces a tap recognizer to
handle that behavior.
To avoid the slider's drag and tap recognizers from competing with each
other in the arena, this patch introduces the notion of a
GestureArenaTeam, which lets several recognizers combine to form one
entry in the arena. If that entry wins, the team picks the first of its
recognizers as the winner, avoiding latency.
Fixes#7454
Now IconThemeData.fallback is a factory constructor and IconThemeData.of() does
the work of computing the fallback for its clients.
Also, add tests for ImageIcon and ListItems.
With frameSync enabled, flutter_driver actions will only be performed
when there are no pending frames in the app under test. This helps with
reducing flakiness.
Previously, it was possible for the test harness to bail
and the test runner to complete before the platform plugin
triggered the collection of coverage data. This fixes the
race condition such that the pending coverage collection
task is recorded immediately after starting the process.
Previously we asserted that the element was not in the dirty list, but there
are scenarios where the element can be in the dirty list already. This patch
makes markNeedsBuild handle those cases by simply resorting the dirty list.
Fixes#6119
The indexes passed to paragraph.getBoxesForRange are based on UTF-16 code
units. If the caret is at a character that is encoded as multiple code units,
then the start and end indexes should be adjusted accordingly.
- output single-line JSON because iOS 9.x cannot output more than one line
- move the workaround for #7433 into LiveTestWidgetsFlutterBinding so that it works in all cases (e.g. animation_bench.dart on iOS)
As of Dart SDK 1.22.0-dev.5.0, `Process.exitCode` is no longer
mutable (that SDK version picks up e5a16b1ca5).
This change allows the tools code to pass analysis in sdk versions both
before and after that change, to allow for analysis against both the host and
target sdks.
Change `Flexible`'s default `FlexFit`
Previously, `Flexible` defaulted to `FlexFit.tight`, which forced the child to
expand to fill the available space. Now, `Flexible` defaults to
`FlexFit.loose`, which does not force the child to expand to fill the available
space.
If you want the child to expand to fill the available space, consider using
`Expanded` instead.
Fixes#5169
We now produce a more reasonable error message when we're missing the
flutter_test dependency in a test. Also, remove the flutter_tools stack traces
when the engine dies.
Fixes#6187
