You can use below to add data into AsyncStorage storage.

onRadioPress2() {
        try {
            const Newlanguage = 'fa';
            AsyncStorage.setItem('language', Newlanguage)
            this.setState({ language: 'fa' });
            RestartAndroid.restart();

        } catch (error) {
        }
    }

You can call the function link:

this.onRadioPress2()

You can retrieve value using the below code:

    AsyncStorage.getItem('language').then((Newlanguage) => {
        this.setState({
            language: Newlanguage
        })
    }).done();

Your mistake is you are using the wrong name while setting the state.

this.setState({ lang: Newlanguage }) --> this.setState({ language: Newlanguage })
