Summary: The user reports that frontend_server.dart.snapshot is missing from their Dart SDK and asks why. This is insufficient information to debug.

Thank you for reporting this issue! To help us understand and resolve the problem, could you please provide the following information:

• The output of dart --version (or dart info)
• Your operating system (e.g., Windows 10, macOS Ventura, Ubuntu 22.04)

This will help us diagnose why the snapshot file is missing. If you're using a specific tool or framework (like Flutter), please also specify that.

See my answer from the linked issue:

Using "dart pub outdated", I found out that the transitive dev_dependencies had an outdated frontend_server_client package. Using "dart pub upgrade" fixed the problem and updated the version to 4.0.0.

transitive dev_dependencies:
...
frontend_server_client      *3.2.0    4.0.0       4.0.0       4.0.0   
...
