Overview
rich_text_controller is a Flutter/Dart package that extends the standard text editing controller to enable inline styling for text based on custom regular expressions. It allows developers to apply different styles—such as colors, fonts, or decorations—to specific patterns within a text field, like hashtags, mentions, or links. Ideal for rich text inputs in messaging apps, note-taking tools, or social media interfaces, it enhances user experience by visually distinguishing structured content. The package supports all major platforms and integrates seamlessly with existing TextEditingController workflows.
