Linux Web Framework tests is pulling the latest framework commit (d377c1baeda6b802be16efdf9ab770bbc8cabe9c), I'm guessing that explains the compilation failure? https://logs.chromium.org/logs/flutter/buildbucket/cr-buildbucket.appspot.com/8851210506222927856/+/steps/run_web_integration_tests/0/stdout

@mdebbar WDYT?

LGTM.

I re-ran build_and_test_linux_unopt_debug since it's not showing what the failure is, and it's known to be flaky in Cirrus.
