inspire_blur 0.4.0

A modern, high-performance progressive blur for Flutter — powered by custom GPU shaders.

0.4.0

Added

• Color adjustments
  • Added blur area color adjustments: brightness, contrast, exposure, saturation, and vibrance via the new BlurColorAdjustment configuration class.
  • Adjustments can be controlled by the InspireBlurConfig.colorAdjustment property.
  • Full support implemented for both child and backdrop blur effects.

Changed

• Data classes: Added lerp() and other utility methods to configuration data classes to support seamless UI transitions and implicit animations.
• Documentation: Optimized docs using templates, improved API wording.

0.3.1

Fixed

• Backdrop blur positioning
  • Added automatic screen-position updates for backdrop blur.
  • Fixed backdrop blur misalignment during route transitions, such as Cupertino swipe-back gestures, and when used inside scrollable lists.

0.3.0

Added

• Custom mask
  • Added customMask() for defining any arbitrary blur distributions using an Image.
  • Works with both child and backdrop blur.
• Blur transformations
  • Added BlurTransform for applying blur distribution transformations, including: scale, offset, rotation, and inversion.
  • Works with both child and backdrop blur.
  • All transformation properties are fully animatable.

Changed

• Breaking changes
  • Replaced InspireBlurConfig.inverse with BlurTransform.inversionFactor.
  • Inversion is now part of blur distribution transformations. The type has changed from bool to double, allowing smooth animation and finer control over the inversion amount.

0.2.0

Added

• Blur shapes: Added ellipse(), rectangle(), and roundedRectangle() blur distributions.
• Color tint: Added the Inspire.tint API with factories for applying a gradually fading accent color on top of blur effects.
• More flexible configuration: Relaxed constraints on several configuration parameters. For example, extent now supports values greater than 1.0, making it more flexible for advanced use cases such as animations.

Fixed

• ImageFilter mode: Fixed a nullptr crash that could occur when using child blur with InspireBlurMode.imageFilter in dynamically changing widget trees.
• Child blur gestures: Fixed a bug where taps and other gestures were not passed through to widgets wrapped with child blur.

Changed

• Breaking change: Blur distribution parameters are now configured through the distribution field of InspireBlurConfig, using dedicated BlurDistribution subclasses for each type of blur distribution.
• Package size: Reduced the published package size from ~15 MB to ~1 MB.
• Example app: Merged the example app source files into one main.dart file that contains a self-contained and minimal copy-pasteable first use example.
• Documentation:
  • Expanded the README.md with the new blur shape factories, blur pattern screenshots, a color tint demo, and a "Support the Project" section.
  • Expanded the API documentation and improved the overall structure, formatting, and readability.
• Unit test coverage: Expanded test coverage for core utilities, including gradient mask generation.

0.1.0

• Initial release
• Centralized Inspire API for quick access
• Progressive blur widgets for child and backdrop mode
• GPU-optimized shader program based on a blur-strength gradient map
• Unit and widget tests for improved reliability
• Example app showcasing all available blur types
