This is what I did, had a similar issue.It works well when you want to remove an item based on its id. make sure each item has a unique id.

remove_user = async(userid) => {
    try{
        let usersJSON= await AsyncStorage.getItem('users');
        let usersArray = JSON.parse(usersJSON);
        alteredUsers = usersArray.filter(function(e){
            return e.id !== userid.id

        })
        AsyncStorage.setItem('users', JSON.stringify(alteredUsers));
        this.setState({
           users:alteredUsers
        })
    }
    catch(error){
        console.log(error)
    }
};
