smooth_bottom_sheet

Modern, animated and production-ready bottom sheets for Flutter apps.

Smooth motion, adaptive themes, and a clean API designed for real projects.

Why this package

Many bottom sheet implementations are either too basic or too tied to one app style.

smooth_bottom_sheet gives you:

• A production-ready visual baseline
• Strong customization without boilerplate
• A reusable architecture to keep UI, config and behavior clean

Features

• Modern sheet container with adaptive light/dark theme defaults
• Smooth entrance animation (slide + fade) with configurable timing/curve
• Configurable layout (radius, padding, max width)
• Header API with title, subtitle, leading and trailing widgets
• Programmatic control via SmoothBottomSheetController
• showSmoothBottomSheet(...) helper for fast integration
• Works on mobile, tablet and desktop layouts

Installation
