Code Review
This pull request removes the --web-experimental-hot-reload flag from the Flutter tool, making web hot reload the mandatory default. The changes involve removing the flag from the argument parser, hardcoding the feature to enabled in the command runner, and updating associated tests and devicelab tasks. Feedback identifies that several locations still attempt to pass the --no-web-experimental-hot-reload flag; because the flag has been removed from the parser, these instances will cause usage errors and should be removed.

This pull request executed golden file tests, but it has not been updated in a while (20+ days). Test results from Gold expire after as many days, so this pull request will need to be updated with a fresh commit in order to get results from Gold. For more guidance, visit Writing a golden file test for Reviewers: Read the Tree Hygiene page and make sure this patch meets those guidelines before LGTMing. |
Cleans up the --web-experimental-hot-reload flag. It was added to roll out the hot reload feature on the web. The option is enabled by default and when used issues a warning that it will be removed in an upcoming release. Removing the ability to disable unblocks the deletion of the code paths that support compiling and running with the require.js AMD module system. Issue: flutter#142060

Removing the ability to disable unblocks the deletion of the code paths that support compiling and running with the require.js AMD module system.
This change intentionally leaves behind the code paths and tests that support the flag to make a potential revert easier. If this change sticks then cleanup will be handled in followup CLs.
