);


🎨 Best Practices
• Use outlined icons for inactive, filled for active
• Keep gradients subtle (2–3 colors)
• Glow opacity between 0.3–0.5 for elegance
• Icon size between 24–32dp for touch targets
• Labels short (1–2 words)
• Ensure contrast between background & icons

📦 Requirements
• Flutter: >=3.0.0
• Dart: >=3.0.0
• flutter_screenutil: ^5.9.
