Overview
CheckedYAML is a Dart package that enhances error reporting when decoding YAML documents, particularly when used with json_serializable. It provides more descriptive and actionable exceptions during YAML parsing, helping developers quickly identify issues like missing fields, type mismatches, or invalid values. By integrating seamlessly with existing serialization workflows, it improves debugging efficiency without requiring changes to data models. The package is especially useful in development environments where clear feedback accelerates troubleshooting.
Use cases
- Debugging YAML parsing errors
- Improving developer experience during serialization
- Enhancing error messages in CI/CD pipelines
- Validating configuration files at runtime
- Supporting structured data input in apps
- Integrating with json_serializable workflows
Key features
