Overview
The regexed_text package enhances Flutter's Text widget by enabling pattern-based text highlighting. It allows developers to identify and style text that matches specified regular expressions, making it ideal for features like syntax highlighting, keyword emphasis, or dynamic text annotations. The package supports multiple platforms including Android, iOS, Web, macOS, and Windows, ensuring consistent behavior across environments. It integrates seamlessly with existing Flutter apps using a simple API. This utility is particularly useful in applications requiring real-time text processing or visual feedback based on content patterns.
