multiGet can return nulls, but the TS types do not reflect this

[lukewlms]

Current behavior

Querying AsyncStorage for an unknown key using multiGet can return null values.

However the types indicate this is impossible.

Expected behavior

Types should indicate that returning null is possible, OR null should never be returned (I don't know which is correct, but I would think the types).

Repro steps

Run code:

  const [testPair] = await AsyncStorage.multiGet(["DOES NOT EXIST"]);
  console.log(testPair);

return value: ["DOES NOT EXIST", null]

Environment

• Async Storage version: Latest

"@react-native-community/async-storage": "^1.2.2",

"react-native": "0.59.1",

• Platform tested: iOS

Hey @lukewlms, thanks for reporting this.

Yes, it seems it slipped through by mistake - obviously, AS can return null if something does not exist.

I'd suggest to update the types. Mind opening a PR?

thanks.
