Merge Risk: 🟡 Moderate · up to Lazy drawer resolution is implemented, but the legacy wrapper exposes the wrong ref type. Correct the public typing before merge so consumers can safely access the drawer instance. 🚥 Pre-merge checks | ✅ 3✅ Passed checks (3 passed)

🟡 Changes recommended
The new LazyDrawerLayoutAndroid is a function component passed into createNativeWrapper, which will receive a React ref and therefore causes a runtime ref warning and breaks createNativeWrapper’s internal ref/handlerTag wiring unless it is ref-forwarding.

Pull request overview
This PR updates the library’s legacy LegacyDrawerLayoutAndroid wrapper to avoid triggering React Native’s DrawerLayoutAndroid deprecation warning at app startup by resolving the underlying RN component lazily on first render, instead of importing it at module load.
Changes:
- Switched
DrawerLayoutAndroidto a type-only import and introduced a lazily-resolved implementation cached in a module-level variable. - Updated
LegacyDrawerLayoutAndroidto wrap the lazy resolver instead of the eager RN import. - Adjusted
LegacyDrawerLayoutAndroid’s exported type to resolve to the drawer instance type (for better ref method typing).

In `@packages/react-native-gesture-handler/src/components/GestureComponents.tsx`:
- Line 128: Update createNativeWrapper to accept and propagate a generic ref
type instead of hardcoding React.ComponentType<any>; instantiate the
LegacyDrawerLayoutAndroid wrapper with React.ComponentRef<typeof
RNDrawerLayoutAndroid> so its ref contract matches the native drawer instance
exposed by LazyDrawerLayoutAndroid.

Description
Since React Native 0.87 the
DrawerLayoutAndroidexport is a getter that logsDrawerLayoutAndroid is deprecated and will be removed in a future releasethroughwarnOnceon first access.GestureComponents.tsximported it at module level to buildLegacyDrawerLayoutAndroid, so every app that imports gesture-handler saw the warning at startup, even if it never rendered a drawer.LegacyDrawerLayoutAndroidnow wraps a small component that readsDrawerLayoutAndroidfromreact-nativeon first render and caches it in a module-level variable, so the warning appears only for apps that actually render the deprecated wrapper. The read usesrequirerather thanimport * as RN, because Metro'sexperimentalImportSupport(enabled by default in Expo) copies every export eagerly and would trigger all of RN's deprecation getters at once.Fixes #4491
