How to properly work with a form in React-Native?

Question

React Native

Greetings!
In Reat, I created a component that renders a simple form (2 fields and a button). By clicking on the button (onSubmit) - I send the data of the entire form to the handler. Now, you need to implement a similar form in React-Native, in connection with this, a few questions:
1. In HTML, it is generally customary to write the form structure as: from->input. In React-Native, I did not find the Form component while inserting a TextInput without a form. React-Native inserting input without form?
2. If there is no form, then I don’t understand how to correctly collect data from input. I tried to do it through ref, but the "value" of the specified field could not be obtained in the handler. So what's the right way to do it?

// отрисовываем форму
return (
    <View>
        <Text style={ styles.h1 }>Авторизация:</Text>
        <View>

            <Text style={ styles.bold }>Login (numeric):</Text>
            <TextInput
                keyboardType="numeric"
                style={ { height: 40, borderColor: "gray", borderWidth: 1 } }
            />

            <Text style={ styles.bold }>Password (default):</Text>
            <TextInput
                ref={ refInputLogin }
                keyboardType="default"
                style={ { height: 40, borderColor: "gray", borderWidth: 1 } }
            />

            <Button
                ref={ refInputPassword }
                color="#841584"
                onPress={ () => props.onFormSubmit(refInputLogin, refInputPassword) }
                title="GO"
            />
        </View>
    </View>
);

// обработчик формы
handleFormSubmit = (login, password) => {
    console.log(login.current.value);
    console.log(password.current.value);
};

I don’t know how you develop something without reading the documentation.
TextInput
Handling Text Input
In the React documentation, the topic of controlled components is also fully covered.
