+# react-native-drawer-layout@4.2.3.patch
+
+Backport of the current upstream `toggleDrawer` from
+[`react-native-drawer-layout`](https://github.com/react-navigation/react-navigation/blob/main/packages/react-native-drawer-layout/src/views/Drawer.native.tsx).
+None of it is released on the 4.x line (4.2.9 is latest and still lacks all of
+it); upstream only ships it on the `5.0.0-alpha` line, which needs Gesture
+Handler 3 and therefore react-native 0.82+. The patch can be dropped when we
+move to drawer-layout 5.x.
+
+The patch has three parts. The first landed in #8952; the other two were added
+when the New Architecture switch (#10980) brought Reanimated 4 with it.
+
+## 1. Deduplicate `toggleDrawer` calls (`animatingTo`)
+
+`toggleDrawer` fires twice for a single swipe: once when the gesture ends, and
+again from the effect that watches the `open` prop, because ending the gesture
+calls `onOpen`/`onClose` which updates our shell state. The second call
+restarts the spring from the current position with no velocity, which reads as
+a stutter mid-animation.
+
+`animatingTo` records which direction is in flight and the second call returns
+early. Fixes the drawer jitter investigated in #8947 and #8949.
+
+## 2. Ignore release velocity that opposes the spring direction
+
+Reanimated 4 rewrote spring termination. With `overshootClamping: true` (which
+this library always passes), the animation now ends as soon as the position
+leaves the corridor between its start and its target:
+
+```js
+const leftBound = startValue >= 0 ? toValue : toValue + startValue
+const rightBound = leftBound + Math.abs(startValue)
+if (current < leftBound || current > rightBound) {
+  return true // terminating
+}
+```
+
+Reanimated 3 only treated *crossing* the target as overshoot, so a spring that
+first moved away from its target (which is what an initial velocity pointing
+the other way produces) was left to swing back on its own.
+
+The consequence on Reanimated 4 is that any release whose velocity opposes the
+direction the drawer settles in ends the spring on its first frame, so the
+drawer teleports instead of animating. Both cases are easy to hit: an aborted
+drag under `swipeMinDistance`/`swipeMinVelocity`, where `nextOpen` keeps its
+current value while the finger was moving the other way, and dragging the
+already-open drawer further past its edge before releasing.
+
+Zeroing the opposing velocity keeps the animation inside the corridor. Real
+flings, whose velocity agrees with the target, are passed through untouched.
+
+## 3. `useLayoutEffect` for the `open` prop
+
+Upstream moved the effect that calls `toggleDrawer(open)` off `useEffect`, so
+the follow-up call described in part 1 happens in the same commit rather than a
+frame later. Part 1 dedupes it either way, but the dedupe window is only as
+long as the spring runs, so not depending on that is worth the one-line change.
+
+## Notes
+
+`restDisplacementThreshold` and `restSpeedThreshold` are left in the spring
+config, but they are inert on Reanimated 4 - it settles on a relative
+`energyThreshold` instead, and those two options survive only as no-op layout
+animation builder methods. The drawer animation is roughly 200ms shorter than
+it was on Reanimated 3 as a result. The spring itself is deliberately left at
+this library's `stiffness: 1000, damping: 500, mass: 3`; upstream has since
+retuned it to an underdamped `500/40/1`, which would change how the drawer
+feels and is a separate decision.
