* Remove the workaround that pinned args to v0.13.6
This reverts most of the changes in commit 6331b6c8b5
* throw exception if exit code is not an integer
* rework command infrastructure to throw ToolExit when non-zero exitCode
* convert commands to return Future<Null>
* cleanup remaining commands to use throwToolExit for non-zero exit code
* remove isUnusual exception message
* add type annotations for updated args package
Add an option to provide a custom description to predicate
finders. Without a custom description we default to printing the
predicate function's signature, which is not all that useful.
Use this new option in the driver extension to print the text of the
sought after tooltip.
This requires all AnimationController objects to be given a
TickerProvider, a class that can create the Ticker.
It also provides some nice mixins for people who want to have their
State provide a TickerProvider. And a schedulerTickerProvider for those
cases where you just want to see your battery burn.
Also, we now enforce destruction order for elements.
Switch our pubspec.yamls to using SDK sources so that we can have consistent
source types when we depend on these packages from external packages using SDK
sources.
* Update tools to use `analyzer` from vended Dart SDK.
* updates `flutter_tools` and `flutter_test` to use the SDK-vended `analyzer` package
* tweaks dependency tracking logic to only record the SDK-vended `analyzer` so as not to crash on spurious conflicts (due to transitive dependencies)
* Review fixes.
Previously, pumpWidget() would do a partial pump (it didn't trigger
Ticker callbacks or post-frame callbacks), and pump() would do a full
pump. This patch brings them closer together. It also makes runApp run a
full actual frame, rather than skipping the transient callback part of
the frame logic. Having "half-frames" in the system was confusing and
could lead to bugs where code expecting to run before the next layout
pass didn't because a "half-frame" ran first.
Also, make Tickers start ticking in the frame that they were started in,
if they were started during a frame. This means we no longer spin a
frame for t=0, we jump straight to the first actual frame.
Other changes in this patch:
* rename WidgetsBinding._runApp to WidgetsBinding.attachRootWidget, so
that tests can use it to more accurately mock out runApp.
* allow loadStructuredData to return synchronously.
* make handleBeginFrame handle not being given a time stamp.
* make DataPipeImageProvider.loadAsync protected (rather than private),
and document it. There wasn't really a reason for it to be private.
* fix ImageConfiguration.toString.
* introduce debugPrintBuildScope and debugPrintScheduleBuildForStacks,
which can help debug problems with widgets getting marked as dirty but
not cleaned.
* make debugPrintRebuildDirtyWidgets say "Building" the first time and
"Rebuilding" the second, to make it clearer when a widget is first
created. This makes debugging widget lifecycle issues much easier.
* make debugDumpApp more resilient.
* debugPrintStack now takes a label that is printed before the stack.
* improve the banner shown for debugPrintBeginFrameBanner.
* various and sundry documentation fixes
This issue got fixed by a recent check-in, but I had a test specifically
for this incarnation so we should probably keep it just in case.
Closes https://github.com/flutter/flutter/issues/5630
Previously, if a StatefulWidget was marked dirty, then removed from the
build, then reinserted using the exact same widget under a widget under
a LayoutBuilder, it wouldn't rebuild.
This fixes that.
It also introduces an assert that's supposed to catch SizeObserver-like
behaviour. Rather than make this patch even bigger, I papered over two
pre-existing bugs which this assert uncovered (and fixed the other
problems it found):
https://github.com/flutter/flutter/issues/5751https://github.com/flutter/flutter/issues/5749
We should fix those before 1.0 though.
Changes in this patch:
- iOS now uses a different scrollDrag constant than Android.
- ScrollConfigurationDelegate now knows about target platforms.
- ScrollBehaviors now know about target platforms.
- RawInputLine now has to be told what platform it's targetting.
- PageableList now has a concept of target platform.
- make debugPrintStack filter its stack.
- move debugPrintStack to `assertions.dart`.
- add support for limiting the number of frames to debugPrintStack.
- make defaultTargetPlatform default to android in test environments.
- remove OverscrollStyle and MaterialApp's overscrollStyle argument. You
can now control the overscroll style using Theme.platform.
- the default scroll configuration is now private to avoid people
relying on the defaultTargetPlatform getter in their subclasses (since
they really should use Theme.of(context).platform).
- fix some typos I noticed in some tests.
- added a test for flinging scrollables, that checks that the behavior
differs on the two target platforms.
- made flingFrom and fling in the test API pump the frames.
- added more docs to the test API.
- made the TestAsyncUtils.guard() method report uncaught errors to help
debug errors when using that API.
We now have 100% coverage of animation.dart and animation_controller.dart.
Also, add some basic tools for working with lcov files. These tools need much
more polish.
* brings in analyzer version (`0.27.4-alpha.14`) corresponding to current Dart SDK (`1.18.0-dev.2.0`).
* updates analysis to use prefered API for embedder URI resolution
* adds trampolines to `State` and `StatelessWidget` to allow for warning-free within-library @protected access (needed since we closed off access to @protected closures from outside subclasses).
* turns off cache dependency tracking for analysis (in DDC this amounted to a 10% speed improvement).
Prep to get us ready to pull in a new dev SDK and bump our analyzer DEP.
* updates `crypto` (required by fresh analyzer)
* fixes newly flagged dead code warnings
* fixes switches that fall through and don't return
