Description

Since React Native 0.87 the DrawerLayoutAndroid export is a getter that logs DrawerLayoutAndroid is deprecated and will be removed in a future release through warnOnce on first access. GestureComponents.tsx imported it at module level to build LegacyDrawerLayoutAndroid, so every app that imports gesture-handler saw the warning at startup, even if it never rendered a drawer.

LegacyDrawerLayoutAndroid now wraps a small component that reads DrawerLayoutAndroid from react-native on 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 uses require rather than import * as RN, because Metro's experimentalImportSupport (enabled by default in Expo) copies every export eagerly and would trigger all of RN's deprecation getters at once.

Fixes #4491

Test plan

  • yarn ts-check, yarn test and yarn lint:js in the package
  • yarn ts-check in apps/basic-example
  • basic-example on Android: no deprecation warning at startup, one warning when opening the Drawer Layout screen; open/close via edge swipe and via ref buttons, drawer callbacks and RectButton presses work

📝 Summary

Summary by CodeRabbit

  • Bug Fixes
    • Improved compatibility for the legacy Android drawer layout by deferring its platform component lookup until rendering.
    • Preserved support for existing references and component usage while avoiding issues caused by deprecated platform access.

Walkthrough

DrawerLayoutAndroid is no longer loaded as a runtime module import. A lazy wrapper requires and caches it during the first render. LegacyDrawerLayoutAndroid uses the wrapper and updates its component and ref types.

DrawerLayoutAndroid lazy loading

Layer / File(s) Summary
Lazy wrapper and legacy export
packages/react-native-gesture-handler/src/components/GestureComponents.tsx
Moves DrawerLayoutAndroid to the type-only imports, adds a cached render-time require, and updates LegacyDrawerLayoutAndroid to use the lazy wrapper with revised ref typing.

Merge Risk: 🟡 Moderate · up to bde08

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.

🟡 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 DrawerLayoutAndroid to a type-only import and introduced a lazily-resolved implementation cached in a module-level variable.
  • Updated LegacyDrawerLayoutAndroid to 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).

- 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
