variable_blur: ^0.1.0 copied to clipboard

✨ Improvements #

• Performance: 40-75% performance boost with 4-tier optimization system
• Blur Range: Extended maximum kernel size to 100 pixels
• ResponsiveBlurSides: Added screen size breakpoint configuration

🔧 Fixes #

• Impeller Issue: Fixed SkSL shader compilation errors when Impeller is disabled on Android
• Cross-Platform: Ensured compatibility with both Impeller and Skia rendering backends

Added #

• Comprehensive documentation for BlurSides (ratio-based, 0–1) and ResponsiveBlurSides (pixel-based) for clarity and ease of use.
• Improved API docs and inline comments for all public classes and methods.

Changed #

• Major performance boost: rendering and blur computation are now significantly faster and more responsive, especially on large images and during dynamic updates.
• Responsiveness improvements: blur effects now adapt more smoothly to widget size and pixel-based configurations.
• Cleaned up and refactored code for maintainability and efficiency.
• Updated all examples and documentation to reflect new best practices and usage patterns.

Fixed #

• Improved handling of edge cases for both ratio-based and pixel-based blur regions.
• Enhanced compatibility and stability across iOS and Android devices.

Added #

• Automatic kernel size calculation based on sigma value and quality setting.
• Simplified API - no more manual kernel size configuration needed!

Changed #

• REMOVED: The kernelSize parameter has been removed to simplify the API.
• IMPROVED: Quality settings now automatically optimize kernel size for best performance vs quality trade-off.
• Cleaned up unused uniforms in shaders (removed edgeIntensity from horizontal pass).
• Updated all examples and documentation to reflect the simplified API.

Fixed #

• Previously, using sigma values greater than 15 was not recommended and could result in poor blur or performance issues.
• Now, kernel size is automatically calculated, making high sigma values safer to use with appropriate quality settings.

• VISUAL: Added comprehensive screenshot gallery to README.md for better pub.flutter-io.cn presentation
• IMPROVED: Enhanced README.md with visual examples showcasing different blur effects
• OPTIMIZED: Refined package description to meet pub.flutter-io.cn character limits (60-180 chars)
• ENHANCED: Added organized image gallery displaying tilt-shift, horizontal, vertical, and dynamic blur effects
• PRESENTATION: Improved package discoverability with prominent visual examples in documentation
• POLISH: Better structured README layout for professional pub.flutter-io.cn package listing

• DOCUMENTATION: Comprehensive API documentation added to meet pub.flutter-io.cn standards (20%+ coverage achieved)
• NEW: Added detailed dartdoc comments for all public API elements
• IMPROVED: Enhanced library-level documentation with features overview and usage examples
• ADDED: Important compatibility notes - blur effects only work on images or colored containers
• ENHANCED: Detailed class and method documentation with performance considerations
• QUALITY: Added comprehensive examples and best practices in documentation
• REFERENCES: Clear references to example app for implementation guidance

• BREAKING FIX: Fixed coordinate system compatibility between iOS and Android platforms
• NEW: Added platform-aware rendering to prevent upside-down blur effects on Android
• IMPROVED: Enhanced cross-platform shader compatibility with automatic coordinate system detection
• TECHNICAL: Added platform detection logic to handle different coordinate origins (iOS: bottom-left, Android: top-left)
• PERFORMANCE: Optimized shader branching for platform-specific coordinate transformations

• Documentation updates and package maintenance

• Internal improvements and bug fixes

• Initial release with variable blur effects
• Tilt-shift blur implementation with GPU shaders
• Customizable blur sides (top, bottom, left, right)
• Performance-optimized blur rendering
• Quality control settings (low, medium, high)
• Cross-platform support for Flutter applications
