Storage not returning string ionic

Question

I've implemented Storage for Ionic (don't know if it's something new to store values).

I've created a service that stores an object (it works, because I've console.logged() it), but when I want to get() it's returning me undefined when I use the same key, even when the console.log() from the get() method prints what I want...

getInfo(keystorage): string {
    var val = null;  
        this.storage.get(keystorage).then((profile) => {
            val = JSON.parse(profile);
            console.log(val["info"]); //returning what I want
            return val["info"];
        })
        .catch((err: any) => {
            return 'catchhhh';
        });
        return val;
    }

It's returning null now because I've added var vall = null and looks like it doesn't change anything...

I store it like this:

saveInfo(usr){
    if(usr==null) return;
    var usertostore = {"id": currentUser["id"], "info":currentUser["info"]};
    this.storage.set("userLoged",JSON.stringify(usertostore ))
  }

I'm trying to get the info like this:

var userInfo = this.storageService.getInfo('myKey');

What am I missing?

This happen because the storage method is asynchronous and the value is null when it is returned.

Can you try this way?

getInfo(keystorage) {
    return this.storage.get(keystorage);
}

saveInfo(usr){
    if(usr==null) return;
    var usertostore = {"id": 1234, "info":"fdsgf"};
    this.storage.set("userLoged",JSON.stringify(usertostore ))
}

and get the info:

getInfo('userLoged').then((res) => {
  var userInfo = res;
});

I've removed the .then((res...) because getInfo it's a void, It's returning undefined

Plus it's returning null because it does not return the value in .then condition from getInfo()

You've set the value stored at userInfo attribute inside .then() function.

ok I did a console.log(userInfo) and it shows the object, but I was looking for to get it from my service and from the splash get the info

@Stuart2041 If you need a synchronous way, I believe that you can't use this storage service
