This reverts commit adc9dde3ba.
- Fixed issue where `FallbackDiscovery` would hold on to a `VmService` when launching on iOS devices, causing DDS to fail to start
- Fixed `flutter drive` case where DDS is already running in another flutter_tools instance
The embedder requires that the isolate is unpaused, because the runInView method requires interaction with dart engine APIs that are not thread-safe. These APIs must be run on the same thread that would be blocked by the pause. Simply unpausing is not sufficient, because this does not prevent the isolate from immediately hitting a breakpoint, for example if the breakpoint was placed in a loop or in a frequently called method. Instead, all breakpoints are first disabled and then the isolate resumed.
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.
Add feature flags for android, ios, and fuchsia (on by default). After updating the g3 rollers, the fuchsia feature will be turned off by default. Creates a simpler base type of feature flags for g3 to extend.
Updates android, ios, fuchsia workflows to use feature flags check.
Removes concept of stable artifacts and checks on flutter version.
Fixes#58999#52859#12768
The Xcode build almost always takes longer than 2 seconds. With the
operation classified as a "fast operation", the Flutter tool will
warn the user that the build is "taking an unexpectedly long time".
This updates the operation to be a "slow operation", which will only
warn the user if it takes 2+ minutes.
Allow configuring the flutter_manifest to support a synthetic package, this is done through flutter: generate: true.
When running pub get, insert a flutter_gen entry into the packages if it does not already exist. This points to .dart_tool/flutter_gen, which can be updated to contain the generated intl sources (But doesn't currently)
Adds an integration test that verifies this code can be run and imported when enabled.
Part of #60914
Enable null safety asserts for web debug mode. This induces runtime asserts at the boundaries between null safe and non-null safe libraries. Adds integration test that validates assertion error is thrown.
