You can now specify a --local-web-sdk flag to point to a wasm_release folder. This will make it so that only artifacts that pertain to the web sdk are overridden to point to the wasm_release folder. Other artifacts (such as impellerc) will pull from the cache, or from the --local-engine path if that is specified. This also uses precompiled platform kernel files for both ddc and dart2js
Web integration tests
These tests are not hermetic, and use the actual Flutter SDK. While
they don't require actual devices, they run flutter_tester
to test
Dart web debug services (dwds) and Flutter integration.
Use this command to run (from the flutter_tools
directory):
../../bin/cache/dart-sdk/bin/pub run test test/web.shard
These tests are expensive to run and do not give meaningful coverage information for the flutter tool (since they are black-box tests that run the tool as a subprocess, rather than being unit tests). For this reason, they are in a separate shard when running on continuous integration and are not run when calculating coverage.
