* Update the following packages
- dart-petitparser to 1.7.5
- dart-xml to 3.0.3
- image to 1.1.30
These updates fix some of the strong mode errors we were encountering
while running flutter tests.
* Update dependencies with forced upgrade.
Now that https://github.com/flutter/flutter/issues/15261 is fixed, do the update with upgrade.
* Update test package use following upgrade
* Replace addOption(allowMultiple) with addMultiOption
30+4 has made some changes to the remoting protocol that are incompatbile
with a test harness running 30+3 (e.g. adding a type='initial' field to the
first message)
* Use engine-built dart sdk
* Download dart-sdk from engine
* Move up deps to fix dart sdk constraint problem
* Update update_dart_sdk.ps1 for Windows
* Fix tests so they pass analysis
* More types for tests
* Roll engine
* Update dart sdk stamp location in flutter.bat
* Add newline
There were some problems I introduced with the last PR for this. It passed the test, but failed in practice.
This adds tests for those failure cases, adds a "--help" and fixes the test so that it doesn't try and actually download MinGit as part of the Windows test.
I added package:platform as a dependency, so I did a force upgrade on the packages.
Also, re-enabling 'create package' in the cache warming code, now that #14448 is fixed.
* Unpin package:test and upgrade packages
* Update packages/flutter/test/foundation/stack_trace_test.dart
* Also add packages/flutter_tools/test/data/asset_test/font/.dartignore to ensure that update-packages --force-upgrade does not crash.
* Revert "Reverting package changes until I can figure out how to fix Windows. (#14007)"
This reverts commit 6fda8ee821dd2e63e7949e57b10efde84bb0a3cc.
* Make prepare_package run on Windows
* Revert "Fixed output validation. (#14005)"
This reverts commit d84398db72807f8910833d5fe44a097be152c74a.
* Revert "Update package prep script to do async process execution and emit output as it happens. (#13918)"
This reverts commit b7169c1d951aa188c1cdc3b980e257e8a92f8abe.
- Switches to async process execution, which now shows output as it happens instead of in chunks when the process completes
- Now uses ProcessManager so that it may be mocked for the test.
- Adds in the download and install of mingit on Windows.
- Updated package dependencies because of added dependency on process package.
This simply updates the package dependencies by running flutter update-packages --force-upgrade.
I'm doing this with no other changes, because the last time I tried that, redness occurred. I want to isolate the problem to a "clean" update of the packages.
It looks like the plugins device_info, connectivity, and url_launcher haven't yet had their gradle configurations updated, so they fail when trying to build with the new gradle. I did not upgrade for those three packages only (in flutter_gallery) until we are ready to fix them (fixing them for master will break them for alpha users, so we need to do an alpha roll to do that).
This adds our self-compiled copy of the MinGit executable (built from the flutter/git repo) to the archive when building an archive for Windows.
I also tweaked the internal API for prepare_package.dart so that there's a single entry point to build an archive.
This consolidates all of the non-template .gitignore rules into the top level .gitignore, to ignore common things more broadly, with less maintenance needed for the .gitignore files. Does not touch the templates, so that they still produce needed .gitignores as part of flutter create.
* fix updrade script; upgrade to the latest package versions
* exclude special dependencies from transitive closure
* fix stack trace handling in flutter_test due to stack_trace change
* change type on _emptyStackTrace
* Add framework-side support for system text scale factor.
* Rolling engine to e3404b81a53ba3180c7623a6f2190ebb28518f30

* Pin all dependencies ONCE AND FOR ALL
This replaces the secret `flutter update-packages --upgrade` with a destructive `flutter update-packages --force-upgrade` that actually goes and pins every dependency and transitive dependency in every flutter package to the same version.
* Add comments.
The main purpose of this PR is to make it so that when you set the
initial route and it's a hierarchical route (e.g. `/a/b/c`), it
implies multiple pushes, one for each step of the route (so in that
case, `/`, `/a`, `/a/b`, and `/a/b/c`, in that order). If any of those
routes don't exist, it falls back to '/'.
As part of doing that, I:
* Changed the default for MaterialApp.initialRoute to honor the
actual initial route.
* Added a MaterialApp.onUnknownRoute for handling bad routes.
* Added a feature to flutter_driver that allows the host test script
and the device test app to communicate.
* Added a test to make sure `flutter drive --route` works.
(Hopefully that will also prove `flutter run --route` works, though
this isn't testing the `flutter` tool's side of that. My main
concern is over whether the engine side works.)
* Fixed `flutter drive` to output the right target file name.
* Changed how the stocks app represents its data, so that we can
show a page for a stock before we know if it exists.
* Made it possible to show a stock page that doesn't exist. It shows
a progress indicator if we're loading the data, or else shows a
message saying it doesn't exist.
* Changed the pathing structure of routes in stocks to work more
sanely.
* Made search in the stocks app actually work (before it only worked
if we happened to accidentally trigger a rebuild). Added a test.
* Replaced some custom code in the stocks app with a BackButton.
* Added a "color" feature to BackButton to support the stocks use case.
* Spaced out the ErrorWidget text a bit more.
* Added `RouteSettings.copyWith`, which I ended up not using.
* Improved the error messages around routing.
While I was in some files I made a few formatting fixes, fixed some
code health issues, and also removed `flaky: true` from some devicelab
tests that have been stable for a while. Also added some documentation
here and there.
