SafeNarrativeWriter class
SafeNarrativeWriter
A protective wrapper around a sentence writer function that avoids writing the same sentence twice in a row. Useful for ensuring idempotent behavior in systems where duplicate instructions can be sent (e.g. during turn-based loops).
Key Responsibilities:
- Prevent repeated visual or audio rendering of identical sentences
- Ensure only new or changed sentences are passed to the delegate writer
- Track last written sentence in memory
Usage Example:
final writer = SafeNarrativeWriter((s) => chatBox.write(s));
await writer.write(sentence); // writes only if not same as previous
