React native asyncstorage get token problem

Question

I tried to get token in register function. But when i called getToken, i get the token but not in the register function. What is the problem? I can't get the token in register() while i called the getToken.

getToken = async () =>{
        let token = await AsyncStorage.getItem('id_token')
        console.log(token)
        return token
    }

    register=()=>{
        var token = this.getToken()
        console.log(token)
        fetch('http://192.168.0.1:8887/api/auth/activities/register',{
            method: 'POST',
            headers:{
                'Accept': 'application/json',
                'Content-Type': 'application/json',
                'Authorization': 'Bearer ' +token,
            },

        })
    }

If you want to call getItem() from another function you can edit your code like this:

getToken = async () => AsyncStorage.getItem('id_token');

register = async () => {
    var token = await this.getToken();
    console.log(token); // Now it should log your token
    fetch('http://192.168.0.125:8887/api/auth/activities/register',{
        method: 'POST',
        headers:{
            'Accept': 'application/json',
            'Content-Type': 'application/json',
            'Authorization': 'Bearer ' +token,
        },

    })
}
