String - Formatting & Case

Essential utilities for managing string case (TitleCase, capitalizing), converting to URL slugs, and handling Base64 encoding/decoding.

1. 🔡 Case & Slugs

   capitalizeFirstLetter() · String

   Capitalizes only the first letter of the string. Returns the string as is if empty.

   print('hello world'.capitalizeFirstLetter()); // "Hello world"
   

   toTitleCase() · String

   Capitalizes the first letter of every word in the string. Ideal for titles and proper nouns.

   print('the quick brown fox'.toTitleCase()); // "The Quick Brown Fox"
   

   toCamelCase() · String

   Converts a snake_case string (e.g., user_data) into camelCase (e.g., userData).

   print('user_profile_data'.toCamelCase()); // "userProfileData"
   

   toSlug() · String

   Converts the string into a clean, URL-friendly slug format, replacing non-alphanumeric

   print('Best Post Ever! (2025)'.toSlug()); // "best-post-ever-2025"
   
2. 🔐 Encoding

   toBase64() · String

   Encodes the string into a Base64 string representation using UTF-8 encoding.

   final encoded = 'secret'.toBase64(); // "c2VjcmV0"
   

   fromBase64() · String

   Decodes a Base64 encoded string back to its original UTF-8 string format.

   final original = 'c2VjcmV0'.fromBase64(); // "secret"
