Regex Match Lab vs FlutterUnit

Keep your regex pattern and its examples together. See matched text, numbered capture groups and source ranges as you edit. Preview replacements before using them elsewhere. Start with Email parts, Log levels or ISO dates, or enter your own pattern and sample. Check edge cases in Test cases. Set each example to Should match or Should not match, then choose Run all. The check looks for a match anywhere in each example. Use \A…\z when you need to check the whole text. Save the pattern, sample, replacement, flags and examples as one test on your device. Reopen it whenever you need to check the same inputs again. From Saved tests, choose Back up saved tests to export a JSON file. Use Restore from JSON and Add copies to bring tests back without replacing existing saved tests. Matching and saved tests work locally, with no account or automatic sync. You choose when to export or share. Large inputs and result counts are limited.

FlutterUnit is a widget explorer and development reference designed for Flutter developers and learners. Quickly discover Flutter widgets, inspect their properties and use cases, interact with live examples, and view the implementation code behind each demo. The examples are rendered with real Flutter widgets rather than static images, so you can interact with them and observe their behavior directly. Key features: • Flutter Widget Library Browse a rich collection of essential and advanced widgets organized by functionality. • Interactive Examples Experience layouts, gestures, animations, painting, scrolling, and other widget behaviors through live demos. • Properties and Usage Review widget descriptions, important properties, related types, and common usage patterns. • Example Code View the Flutter code behind each demonstration and learn how widgets are configured and composed. • Related Widget Navigation Move quickly between related widgets such as Row, Column, Flex, Expanded, and Spacer to build a clearer understanding of the framework. • Search and Favorites Find widgets by name and save frequently used content for quick access during development. • Flutter Plugin Library Explore plugins for state management, UI, networking, data storage, and more. Review platform support, versions, popularity, and essential package information. • Painting and Learning Resources Explore Flutter painting, layouts, animation, gestures, and practical development knowledge. FlutterUnit is useful for beginners learning Flutter, experienced mobile developers, and anyone who needs a convenient widget reference during daily development. FlutterUnit is open source.
