how to remove an item from AsyncStorage in react-native

Question

how to remove an item from AsyncStorage? right now I am trying this code

AsyncStorage.removeItem(\'userId\');

but this is not working for me.

Answer 1

This is the framework code for AsyncStorage.removeItem:

removeItem: function(
 key: string,
 callback?: ?(error: ?Error) => void
): Promise {
 return new Promise((resolve, reject) => {
  RCTAsyncStorage.multiRemove([key], function(errors) {
    var errs = convertErrors(errors);
    callback && callback(errs && errs[0]);
    if (errs) {
      reject(errs[0]);
    } else {
      resolve(null);
    }
  });
 });
}

As you can see above it requires the key(Which is name of the item you set in asyncstorage that you want to delete) and a callback function. Make sure you have the correct key and the correct params and it should work fine.
