To support #61407 , the tool needs to check if a single widget reload is feasible, and then conditionally perform a fast reassemble.
To accomplish this, the FlutterDevice class will have a WidgetCache injected. This will eventually contain the logic for parsing the invalidated dart script. Concurrent with the devFS update, the widget cache will be updated/checked if a single widget reload is feasible. If so, an expression evaluation with the target type is performed and the success is communicated through the devFS result. An integration test which demonstrates that this works is already present in https://github.com/flutter/flutter/blob/master/packages/flutter_tools/test/integration.shard/hot_reload_test.dart#L86
Finally, when actually performing the reassemble the tool simply checks if this flag has been set and calls the alternative reassemble method.
Cleanups:
Remove modules, as this is unused now.
The global packages path could cause tests to fail when it would be overriden to unexpected (in test setup) values. Remove most usage and make it a configuration on buildInfo, along with most other build information. Cleanup the asset builder to require the .packages path and the resident runners to no longer require it, since they already have the information in build_info.
It needs to stick around for the fuchsia deps we do not control.
Filled #60232 for remaining work.
Refactors KernelCompiler and ResidentCompiler to no longer use globals (except as a fallback for g3 migration). Improves the compilation error when running flutter test on a package without a flutter_test dependency.
Updates machine mode to output trace text to stderr
Make it possible for all FlutterCommands to be global free, by moving instantiation to inside the Zone context. Additionally, provide VerboseLogger and NotifyLogger (daemon) at the top level and remove from command-specific overrides.
This allows removing a work around where web devices needed to look up directly from the context in non-test code.
Technically the output preferences are still zone injected, but these will be moved soon as they were not being used correctly by the top level command (the injection comes after ArgParser reads the overflow values, causing numerous wrap issues)
Previously the AdbLogReader did async setup in the StreamController.onListen callback, specifically it would query the api version and start the adb process. If the log subscription was cancelled before this setup completed, then the log output could (haven't confirmed) get added to a closed controller, causing the above state error.
* Update project.pbxproj files to say Flutter rather than Chromium
Also, the templates now have an empty organization so that we don't cause people to give their apps a Flutter copyright.
* Update the copyright notice checker to require a standard notice on all files
* Update copyrights on Dart files. (This was a mechanical commit.)
* Fix weird license headers on Dart files that deviate from our conventions; relicense Shrine.
Some were already marked "The Flutter Authors", not clear why. Their
dates have been normalized. Some were missing the blank line after the
license. Some were randomly different in trivial ways for no apparent
reason (e.g. missing the trailing period).
* Clean up the copyrights in non-Dart files. (Manual edits.)
Also, make sure templates don't have copyrights.
* Fix some more ORGANIZATIONNAMEs
* de-null dartDefines in daemon mode
* remove daemonCommand; pipe through dartDefines into Daemon
* pass dartDefiles in attach; add test for --machine mode
