AsyncStorage.getItem() doesn't seem to work

---

This issue was originally created by @mrded as facebook/react-native#18372.

---

When I try to set a value via AsyncStorage.getItem(), I cannot request it back.

Environment

Environment: OS: macOS High Sierra 10.13.3 Node: 9.8.0 Yarn: 1.5.1 npm: 5.6.0 Watchman: 4.9.0 Xcode: Xcode 9.2 Build version 9C40b Android Studio: Not Found

Packages: (wanted => installed) react: ^16.3.0-alpha.1 => 16.3.0-alpha.1 react-native: 0.54.0 => 0.54.0

Expected Behavior

await AsyncStorage.setItem('foo', 'bar');
await AsyncStorage.getItem('foo').then(console.log); // 'bar'
await AsyncStorage.getAllKeys().then(console.log); // ['foo']

Actual Behavior

await AsyncStorage.setItem('foo', 'bar');
await AsyncStorage.getItem('foo').then(console.log); // null
await AsyncStorage.getAllKeys().then(console.log); // []

Steps to Reproduce

import { AsyncStorage } from 'react-native';

it('should be able to request a value after it was set', async () => {
  await AsyncStorage.setItem('foo', 'bar');
  const output = await AsyncStorage.getItem('foo');

  expect(output).toBe('bar');
});

it('should be able to see a new key after a value was set', async () => {
  await AsyncStorage.setItem('foo', 'bar');
  const output = await AsyncStorage.getAllKeys();

  expect(output).toContain('foo');
});

We recently saw issues with this in our app on a large number of android devices when doing something very similar to the above in production but we had issues reproducing locally. Very happy to help do the work necessary to fix this. Would be great to use this thread to maybe identify what’s causing the issue and different approaches we could use to fix.
