If the tool is downloaded from a precompiled snapshot, or if the backing source files in the pub cache are deleted, the dwds debugging functionality will break as the client.js file cannot be located. Instead use the PackageConfig to verify that package location, downloading if it is missing.
Override the dwds middleware to avoid Isolate.resolvePackageUri

Generates version.json in web directory of project. version.json can be used in the future version of package_info which will support web. version.json has the following keys : app_name, version and build_number. This file is generated every time a user runs or builds the project.

Currently flutter run -d web creates a server with the x-frame-options: SAMEORIGIN added by default (shelf add it's by default). This doesn't allow you to use it inside a frame.
I am trying to build an embedded simulator in vscode and it requires using an iframe.
With this PR I remove the header for debug and profile mode.
Like Android/iOS, only enable --null-assertions if asked. Previously this was enabled by default for web, but in general this has proved to be too breaking to enable by default.

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.
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.
#61042
Made flutter tools serve metadata produced by the frontend server:
pass --experimental-emit-metadata flag to flutter engine
store and serve metadata from web asset server
store and serve merged metadata from web asset server
add tests to verify that metadata is served from memory
update dwds version so it can read metadata
configure dwds to read metadata from file
Prerequisite changes (landed):
sdk: https://dart-review.googlesource.com/c/sdk/+/150181
flutter engine: flutter/engine#19168
webdev:dart-lang/webdev#1064
In web debug mode, infer sound null safety by default. When sound null safety is enabled, provide a separate dill and precompiled Dart SDK. Release builds do not need this setting since we run dart2js from source.
Fixes#59873
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.
WebAssetServer could fail if some of the global statics it depended on were initialized in a different order. Fix this by removing globals.
Delete dwds startup test that needs to spawn a real server.
