super_string_utils 1.1.1

A production-ready collection of String extension methods for Dart and Flutter. Features include validation, transformation, extraction, masking, and fuzzy matching.

super_string_utils

A production‑grade Flutter utility engine delivering 80+ powerful String extensions and Fluent UI builders for modern Dart & Flutter development.

---

🚀 Why super_string_utils?

Dart’s native String class is powerful — but modern applications demand far more.

Validation. Hashing. Parsing. Extraction. Layout generation. UI building.

Developers repeatedly rewrite regex patterns, widget boilerplate, and transformation helpers.

super_string_utils eliminates that repetition.

It bridges the gap between raw strings and production-ready Flutter UI using a clean, fluent, and chainable architecture.

Built for serious Flutter developers who value speed, clarity, and scalability.

🎨 Fluent UI Builders

Stop writing repetitive Flutter boilerplate.

📝 Text Builder

"Super String".toTextBuilder
    .size(20)
    .weight(FontWeight.w600)
    .color(Colors.indigo)
    .padded(EdgeInsets.all(16))
    .insideContainer(
      color: Colors.grey[200],
      borderRadius: BorderRadius.circular(8),
    )
    .center()
    .build();

🔔 SnackBar Builder

"Action Success".toSnackbarBuilder
    .floating()
    .color(Colors.green)
    .withCloseIcon()
    .build();

---

📐 Advanced List Layout Engine

Generate dynamic layouts from List<String> with per-index customization.

["Header", "Content Body", "Footer"]
    .toTextColumn()
    .spacing(12)
    .crossAxis(CrossAxisAlignment.start)
    .style(TextStyle(fontSize: 14))
    .containerAt(0, color: Colors.blue)
    .expandAt(1)
    .align(TextAlign.right)
    .build();

This enables flexible UI construction for menus, dashboards, and dynamic layouts.
