morph_route 0.1.0

iOS 26-inspired container morph for Flutter. A modified OpenContainer with backdrop blur, accent scrim, 3D tilt, and a scaffold-level recede helper — drop-in widgets to make any tile-to-screen navigat [...]

Changelog

0.1.0 — Initial release

First public-shaped cut. Extracted from a Flutter wallet app where the morph shipped on the Send flow.

OpenContainer

Vendored from package:animations (BSD-3) with the following modifications:

• No more Material. Replaced with Container + ShapeDecoration so we don't inherit the ink splash, default elevation paint, or animationDuration for color changes. Custom shadow tokens via closedShadows / openShadows.
• Dropped closedElevation / openElevation and the elevation tween.
• Tunable scrim color. scrimColor (default transparent) replaces the hard-coded Colors.black54.
• Backdrop blur. closedBlurSigma / openBlurSigma — the route inserts a BackdropFilter that lerps with the morph curve so the underlying screen progressively goes out of focus.
• 3D tilt. peakTiltY / peakTiltX / tiltPerspective — iOS 26-style perspective rotation that peaks at the morph's midpoint (sin(π·t)) and is 0 at both endpoints.
• activeProgress. Static ValueNotifier<double> published every animation tick so widgets outside the route (the host shell) can react in lock-step.
• reverseTransitionDuration. Override for snappier closes than opens.
• Pop fix. _takeMeasurements no longer re-reads the source rect on pop — upstream walks through every transform on the underlying screen (getTransformTo(navigator)), which lands the close at a transformed rect if the host applies its own transform during the morph (e.g. via [MorphRecede]).

MorphTile

Pressable wrapper around OpenContainer. Adds:

• Tap handling (so you don't have to wire tappable: false plumbing).
• Press feedback: subtle AnimatedScale (default 0.98) + optional tinted overlay color.
• onTap hook for haptics / analytics.

MorphRecede

Scaffold-body wrapper that scales down (and optionally translates) as a morph route opens, synced to OpenContainer.activeProgress. Pluggable progress source via the progress parameter for custom integrations.
