liquid_glass_bottom_nav 0.0.14

A beautiful, liquid frosted-glass floating bottom navigation bar for Flutter.

0.0.14

• Change: LiquidGlassNavBar's held-tab feedback replaced. The old drag tilt (rotateZ + direction-dependent squash/stretch driven by horizontal drag delta) is gone. In its place: a direction-independent vertical spring squash that responds continuously to drag movement and settles back to neutral with a subtle overshoot (Curves.easeOutBack) once the finger pauses.
• Change: dragRainbowBorder now defaults to false. The held bubble's default accent is a light gray stroke instead of the iridescent sheen; the rainbow ring is still available by setting dragRainbowBorder: true. The stroke now renders consistently whether liquidActiveBubble is on or off.
• Change: liquidActiveBubble now defaults to true — the held bubble renders as a real LiquidGlass shape by default. See the updated doc comment for the per-frame shader-recompute tradeoff on low-end Android hardware; set to false to opt back into the plain tinted container.

0.0.13

• Fix: equatable constraint lower bound (^2.0.7) allowed resolving to a version where Equatable isn't a mixin class, which broke with Equatable in LiquidGlassSettings/LiquidShape and failed pub.dev's dependency-lower-bound (downgrade) check. Bumped to ^2.1.0, the version that introduced mixin class Equatable.
• Fix: three shaders (liquid_glass_geometry_blended.frag, liquid_glass_filter.frag, liquid_glass_arbitrary.frag) failed to compile on the Skia/non-Impeller fallback backend (used on some older/unsupported Android devices), crashing app startup with impellerc failure: Compilation failed for target: SkSL. Root causes: (1) the shape-data array was passed by value into a nested helper function, which spirv-cross cross-compiles to an SkSL array copy-with-initializer that SkSL rejects; inlined the helper so the array is only ever a single-level parameter. (2) a blur-radius loop used a non-const local as its bound, which SkSL requires to be a literal constant; hardcoded the loop bounds. No visual or API changes.

• Docs: replace the top-of-README demo placeholder with a real screenshot of the example app (assets/demo.png).

0.0.11

• Add dragRainbowBorder to LiquidGlassNavBar (default true) — while a tab is held/dragging, its border becomes a soft iridescent "soap bubble" sheen (blurred pastel gradient rim + glossy highlight) instead of a flat activeColor stroke. Plain CustomPainter effect, no extra per-frame cost. Set to false to keep the old flat border.
• Add liquidActiveBubble to LiquidGlassNavBar (default false, opt-in) — renders the held drag bubble as a real LiquidGlass shape instead of a plain tinted container. Only applies while actively dragging; the resting selected bubble is unaffected. Off by default: this animates the glass shape's position/size every drag frame, forcing a per-frame shader recompute — test on real mid/low-end Android hardware before enabling in production.
• Fix: migrate LiquidGlassSettings and LiquidShape off the deprecated EquatableMixin to Equatable (usable as a mixin since equatable 2.1.0), resolving a pub.dev static analysis warning.

0.0.10

• Add badgeCount, badgeColor, badgeTextColor, badgeBorderRadius to LiquidGlassNavItem — shows a small notification badge on a tab's icon, styled per-item. badgeCount null or <= 0 hides the badge; values above 99 display as "99+". Works in both Impeller and legacy fallback modes.
• Add borderRadius param to LiquidGlassNavBar (default 34.0) — customizes the corner radius of the floating capsule. The active tab bubble indicator now follows the same radius instead of always rendering as a full pill.

0.0.9

• Add fake param to LiquidGlassContainer — when true, renders the cheap FakeGlass approximation instead of the real refraction shader. No geometry shader, no per-frame transform tracking, so it stays smooth inside scrolling/paging content. Best for glass placed over a flat/solid background, where real refraction has nothing meaningful to refract.
• Add fake and ownLayer params to LiquidGlassBackButton, matching the options already on LiquidGlassContainer. fake: true avoids Android overscroll distortion artifacts when the button sits inside scrolling/paging content.

0.0.8

• Add ownLayer param to LiquidGlassContainer — when false, the container joins a parent LiquidGlassLayer instead of creating its own layer, reducing N shader passes to 1 for grouped cards.
• Add backgroundColor param to LiquidGlassContainer — true opaque solid fill inside the glass shape, independent of the glassColor shader tint. Enables iOS-native-style solid-color glass containers.
• Add saturation and thickness params to LiquidGlassContainer — previously hardcoded, now fully customizable for vibrancy and refraction tuning.
• Export LiquidGlassLayer and LiquidGlassSettings from the main library entry point.
• Add LiquidGlassRenderScope.maybeOf(BuildContext) for safe scope detection.
• Nav bar light mode: active bubble indicator now uses activeColor tint instead of white, making it visible against the white capsule background.
• Nav bar light mode: capsule glassColor alpha increased to 0.76 and blur settled at 1 for clean vibrant white appearance without fogging.

0.0.7

• Add LiquidGlassBackButton — floating frosted-glass back button with chevron icon, touch glow via GlassGlow, and press scale feedback. Falls back to plain IconButton on non-Impeller targets.
• Tune glass settings for stronger liquid glass refraction: higher thickness (32), lower blur (1), reduced glassColor opacity — applies to both nav bar and back button.

0.0.6

• Add demo GIF placeholder to README — drop assets/demo.gif to activate.
• Wire assets/ directory for hosting demo media.

0.0.5

• Add example/ app with interactive demos: dark/light mode toggle, 3/4/5 tab selector, active color picker, icon size slider, and legacy fallback toggle.
• Add CLAUDE.md and AGENTS.md with commit convention, renderer performance rules, and workflow guidelines.

0.0.4

• Add iconSize param to control icon size across all tabs (default: 22).
• Add labelStyle param for custom label typography, merged over bodySmall. Color always follows active/inactive color.
• Add iconWidget to LiquidGlassNavItem for custom icon widgets (SVG, asset, painter). Takes priority over icon; wrapped in IconTheme for automatic color inheritance.
• Make icon optional in LiquidGlassNavItem — required only when iconWidget is not provided.
• Fix held bubble capsule clipping outside leftmost/rightmost tab boundaries during drag.
• Rewrite README with full API reference, usage examples, and Impeller setup instructions.

0.0.3

• Embed liquid_glass_renderer internally for zero-dependency usage.
• Add physics-based squish and stretch animations that react smoothly to drag velocity.

0.0.2

• Update metadata and prepare for initial release.

0.0.1

• Initial release of liquid_glass_bottom_nav.
