How to use the react-navigation.StackActions.reset function in react-navigation

export const navigateToRoot = () => {
    // navigate(ROOT_SCREEN);
    _navigator.dispatch(
        StackActions.reset({
            index: 0,
            actions: [NavigationActions.navigate({ routeName: ROOT_SCREEN })]
        })
    );
};

_validationPassword = () => {
    let passwordLegal = Util.checkPassword(this.state.password)

    if (passwordLegal) {
      Keyboard.dismiss()
      // 不是 android 手机的情况下才调用 notice (各种不同厂家的状态栏不一样没法统一处理)
      !this.from ? bouncedUtils.notices.show({
        type: 'success', content: '注册成功'
      }) : bouncedUtils.notices.show({
        type: 'success', content: '修改成功'
      })
