string_extensions 0.7.4

Useful String extensions to save you time in production. Feel free to contribute with PR.

0.7.4 Security & Bug fixes

• Adds endsWithAny method to check whether a String ends with any pattern provided in a List
• Fixes division by zero vulnerability in readTime method by adding parameter validation
• Fixes array index out of bounds issues in charOccurences, mostFrequent, and toCamelCase methods
• Improves isIpv6 validation security by replacing complex regex with Uri.tryParse() to prevent ReDoS attacks
• Improves isUrl validation security by replacing regex with Uri.tryParse() and adding scheme validation

0.7.3 Improvements

• Improves after & before methods to include whitespace in patterns
• Adds topics at the library

0.7.2 New parameter

• Adds a new optional parameter, defaultToBlank, to the after and before methods. The defaultToBlank parameter allows the user to specify whether to return an empty string or the original string when no pattern is found. By default, it is set to true, meaning an empty string is returned. This enhancement improves the flexibility and usability of the methods.
