Waiting for AsyncStorage.getItem()

Question

I am using AsyncStorage in my React Native application to store information about the user. The getItem() function is asynchronous and requires me

Answer 1

You can try either add a then after your getItem.

AsyncStorage.getItem("phoneNumber").then((value) => {
    this.setState({"phoneNumber": value});
})
.then(res => {
    //do something else
});

Or use await to wait the async operation to finish

var value = await AsyncStorage.getItem(STORAGE_KEY);
//use value to do something else.
