The change in [0] increased the language version of pkg/dart2wasm. That in return changes how the package is formatted by the autoformatter. This CL runs now the formatter to re-format the code. Unfortunately this makes blame lists worse. But not doing it will make us have to disable auto-formatting before saving files which is very annoying.
