## ◆ VALIDATION_LOG

#define VALIDATION_LOG ::impeller::ValidationLog{}.GetStream()

Get a stream to the log Impeller uses for all validation errors. The behavior of these logs is as follows:

- Validation error are completely ignored in the Flutter release runtime-mode.
- In non-release runtime-modes, validation logs are redirected to the Flutter `INFO` log. These logs typically show up when verbose logging is enabled.
- If `ImpellerValidationErrorsSetFatal` is set to `true`, validation logs are fatal. The runtime-mode restriction still applies. This usually happens in test environments.
