Description

This PR prevents flutter_tools from crashing when standard output/error is broken and the fallback logging with print also throws a FileSystemException (e.g. Broken pipe).

Specifically:

  • In Stdio, introduced _safePrint which catches and ignores exceptions thrown by print when stdout/error streams are broken or closed.
  • Replaced fallback print invocations in stdoutWrite, stderrWrite, and _stdioWrite with _safePrint.
  • Added unit tests in packages/flutter_tools/test/general.shard/base/io_test.dart verifying that stdoutWrite does not crash when writes fail asynchronously or when the stream is already closed.

Code Review

This pull request introduces a private _safePrint helper in Stdio to catch and ignore exceptions when printing to standard output or error streams fails, and adds corresponding unit tests. Feedback suggests catching Exception instead of Object in _safePrint to avoid silently masking programming bugs, in accordance with Effective Dart guidelines.

Oh wow, I had never considered that print could fail!

Oh wow, I had never considered that print could fail!

File it away with the other "random Dart CLI tool facts" for next time 😉
