glassmorphism 4.0.0

Glassmorphic (frosted glass) containers for Flutter with backdrop blur, gradient fill, gradient borders, shadows and size-to-child layout.

4.0.0

Maintenance release that fixes long-standing bugs, adds the most requested features and brings the package up to date with current Flutter.

Breaking changes

• Requires Dart 3.5 / Flutter 3.24 or newer.
• blur is now applied uniformly. Previously the vertical blur was silently doubled (sigmaY: blur * 2). To keep the old, stronger look, increase blur.
• GlassmorphicFlexContainer.padding now pads the child inside the glass. Previously it inset the glass itself, which is what margin is for.
• GlassmorphicFlexContainer.flex is a non-nullable int (default 1).
• linearGradient and borderGradient are typed as Gradient, so radial and sweep gradients work too. Code that reads these fields as LinearGradient needs a cast.

New features

• GlassmorphicContainer.width and height are optional. Without them the glass sizes itself to its child, like Container (#1, #6, #12).
• boxShadow adds drop shadows. They are painted only outside the glass, like CSS box-shadow, so they do not darken the translucent fill (#10).
• shape: BoxShape.circle is now supported. The parameter already existed but was ignored.
• clipBehavior controls how the child is clipped to the glass.
• Constructors are const.

Fixes

• Fixed 'dart:ui/geometry.dart': Failed assertion when border is larger than borderRadius or the container has zero size (#14).
• Fixed "Multiple widgets used the same GlobalKey" when a GlobalKey is passed. The key was also applied to an inner widget.
• GlassmorphicContainer.padding was ignored. It is now applied.
• GlassmorphicFlexContainer.margin and constraints were ignored. They are now applied.
• Widgets no longer require a Directionality ancestor.
• The border no longer rebuilds on every MediaQuery change and only repaints when its properties change.
• blur: 0 skips the BackdropFilter entirely.

Other

• Added widget tests, lints and CI.
• Reworked the example app. The showcase screen with live pub.dev stats now uses pub.dev's JSON API instead of scraping HTML. It loads without blocking startup, handles errors with a retry button and also works on the web. A new gallery page shows every feature. Regenerated the platform folders for current Flutter.
• Removed committed build artifacts, IDE files and lock files.
