Multi-line Strings Prefer using multi-line strings (''') over concatenating strings with + and \n, especially for large blocks of text like SQL queries, HTML, or PEM-encoded keys. This improves readability and avoids lineslongerthan80chars lint errors by allowing natural line breaks.

Robust extractions of values from a Map with Switch Expressions When parsing Map structures or JSON (e.g., from jsonDecode), use switch expressions with object patterns for deep validation and extraction. This is clearer and safer than manual is checks or as casts.

This pattern cleanly handles deeply nested structures and nullable fields without the complexity of verbose if-else blocks or the risk of runtime cast errors.
