release()

void
Defined in: node_modules/expo-modules-core/build/ts-declarations/SharedObject.d.ts:18
A function that detaches the JS and native objects to let the native object deallocate before the JS object gets deallocated by the JS garbage collector. Any subsequent calls to native functions of the object will throw an error as it is no longer associated with its native counterpart.
In most cases, you should never need to use this function, except some specific performance-critical cases when
manual memory management makes sense and the native object is known to exclusively retain some native memory
(such as binary data or image bitmap). Before calling this function, you should ensure that nothing else will use
this object later on. Shared objects created by React hooks are usually automatically released in the effect’s cleanup phase,
for example: useVideoPlayer() from expo-video and useImage() from expo-image.
