https://github.com/flutter/flutter/pull/118104 had the line: ``` _logger.startProgress( 'Loading devices...', ); ``` With `--machine` that line emitted to stdout, and not as valid JSON. It was reverted https://github.com/flutter/flutter/pull/118826. `startProgress` should be fixed to handle `--machine`.
