Keep entered values after error

[CharlotteRdn]

Version

Tell us which versions you are using:

• tcomb-form-native v^0.6.20

Expected behaviour

I did a form using tcomb form native. I would like to keep the values of the previous fields when the user make an error.
I guess it's possible but I don't know how...

Actual behaviour

when I validate the form, if there is an error every field value vanishes. How could I keep them ?

const Form = t.form.Form;

const Email = t.refinement(t.String, email => {
  const reg = /[a-z0-9!#$%&'*+/=?^_`{|}~-]+(?:\.[a-z0-9!#$%&'*+/=?^_`{|}~-]+)*@(?:[a-z0-9](?:[a-z0-9-]*[a-z0-9])?\.)+[a-z0-9](?:[a-z0-9-]*[a-z0-9])?/; //or any other regexp
  return reg.test(email);
});

const Phone = t.refinement(t.maybe(t.String), phone_number => {
  if (phone_number.length === 0) {
    // => ICI, trouver une condition pour vérifier si c'est vide. Si oui, en renvoi TRUE.
    return true;
  }
  const reg = /^(?:\+\d{1,3}|0\d{1,3}|00\d{1,2})?(?:\s?\(\d+\))?(?:[-\/\s.]|\d)+$/; //or any other regexp
  return reg.test(phone_number);
});

const Pwd = t.refinement(t.String, password => {
  const reg = /^(?=.{8,})/; //or any other regexp
  return reg.test(password);
});

const User = t.struct({
  email: Email,
  password: Pwd,
  phone_number: Phone,
  terms: t.Boolean
});

const formStyles = {
  ...Form.stylesheet
};

const options = {
  fields: {
    email: {
      label: i18n.t("signup.input.email"),
      error: i18n.t("signup.error.email")
    },
    password: {
      password: true,
      secureTextEntry: true,
      label: i18n.t("signup.input.password"),
      error: i18n.t("signup.error.password")
    },
    phone_number: {
      label: i18n.t("signup.input.phone"),
      error: i18n.t("signup.error.phone")
    },
    terms: {
      label: i18n.t("signup.input.terms"),
      error: i18n.t("signup.error.terms")
