Changelog Description
Ignore exceptions when trying to set the echo mode of the terminal when the STDIN pipe has been broken.
Impacted Users
flutter developers who use flutter run ...
Impact Description
I'm not sure the exact way users get in this situation, but it is our top tool crasher. Somehow, users are triggering flutter run, but when the tool attempts to modify the STDIN file descriptors echo mode, it reaches an exception that the STDIN pipe has been broken.
Without this fix, the tool will crash and the app will not be run. With this fix, the tool will continue launching the app, without modifying the STDIN echo mode (which shouldn't matter since there's no longer anything attached to STDIN anyway).
Workaround
It's unclear to me the workaround here since I'm not sure why the STDIN pipe is being broken.
Risk
low
Test Coverage
yes
Validation Steps
Unclear to me, see "Impact Description". The unit test in the CP PR at least will verify that at the point the crash is happening we will catch StdinExceptions.
