both base and prefix are omitted; require a configured namespace or an explicit
opt-in before clearing, while preserving scoped clearing behavior for namespaced
storage.
- Around line 47-53: Update the AsyncStorage driver’s setItemRaw and getItemRaw
methods to use the raw serialization and deserialization helpers explicitly,
converting values to the string format required by AsyncStorage and decoding
retrieved values. Preserve the existing key resolution and regular setItem
behavior.
- Line 33: Update the lazy import callback used by importLib so it returns the
AsyncStorage default export rather than the dynamic-import module namespace.
Preserve the injected lib path and ensure getStorage receives an object exposing
getItem and setItem when lib is omitted.
- Around line 58-62: Update getKeys to combine its requested base argument with
the configured namespace when constructing the filter prefix, then filter
storage keys by that combined prefix and strip it before returning results.
Preserve the existing behavior when no base is provided.
In `@test/drivers/react-native-async-storage.test.ts`:
- Around line 37-38: Update the test around driver.clear() to assert scoped
removal via lib.multiRemove with the expected app-prefixed keys, and verify
unrelated keys remain; remove the incorrect lib.clear assertion.

Import createStorage in the usage snippet.
The example calls createStorage but does not import it. Add import { createStorage } from "unstorage"; so the example is copyable.

Unwrap the default export from the lazy import.
When lib is omitted, importLib returns the dynamic-import result unchanged. getStorage() therefore receives the module namespace instead of the AsyncStorage default export, so calls to getItem and setItem can fail. The tests inject lib and do not cover this path.

Let Unstorage handle raw-value serialization.
createStorage calls these driver methods directly, so they bypass serializeRaw and deserializeRaw. AsyncStorage.setItem accepts only strings, but setItemRaw passes binary values directly. getItemRaw returns the stored string without decoding it. Remove these methods, or apply the raw serialization helpers explicitly.

Honor the base argument in getKeys.
createStorage.getKeys(base) passes the normalized base to driver.getKeys. This method ignores that argument and lists every key under the configured driver namespace. A call such as getKeys("s1") can therefore return keys outside the s1 subtree. Combine the requested base with the configured namespace, filter by the resulting prefix, and strip that prefix before returning keys.

official @react-native-async-storage/async-storage API clear removes all AsyncStorage data
💡 Result:
Yes, the clear method in @react-native-async-storage/async-storage removes all data stored within your application's AsyncStorage instance [1][2][3]. While some legacy documentation may contain warnings suggesting it affects other apps or clients, this is not accurate for the modern, standalone @react-native-async-storage/async-storage package [4]. Because this library is isolated to your specific application, calling clear will not affect other applications on the device [4]. However, it is important to note that clear will remove all data for your app, including any data persisted by third-party libraries that also use AsyncStorage within your application [4]. For this reason, developers are often advised to use removeItem or multiRemove if they intend to clear only specific keys rather than the entire storage database [2][3].

Avoid an unscoped global clear.
When base and prefix are omitted, this branch calls AsyncStorage.clear(). That API removes all entries in the app's shared AsyncStorage store, including data written by other libraries. Require a namespace, or make global clearing explicit.

Assert scoped removal instead of global clear.
With base: "app", driver.clear() computes a non-empty key prefix and calls multiRemove; it does not call lib.clear(). This assertion fails. Assert the removed keys and verify that unrelated keys remain.
