# suggestions abstract method

List<String> suggestions(

1. String key

)

Configuration Suggestions

Returns a list of suggestions for the given `key`. Suggestions are typically generated based on partial matches, available configuration keys, or introspection of the environment.

# Example

    final hints = env.suggestions('db.us');
    print(hints); // might print ['db.user', 'db.username']

# Use Cases

- Improving developer experience with autocompletion or hints.
- Detecting typos in property keys by suggesting valid alternatives.

# Notes

- The behavior is implementation-specific and may involve fuzzy matching or prefix-based lookups.
- Returns an empty list if no suggestions are found.

## Implementation

    List<String> suggestions(String key);
