Error savesearch is not a function. savesearch' is an instance of Object

I present the following error: TypeError: savesearch is not a function. (In 'savesearch((0, _extends2.default)({}, search, { country: country }))', 'savesearch' is an instance of Object)

below my code

Form.js
In this js file I have placed everything regarding the form, in this case a picker to select a country and a button so that when pressed it consults an api and can obtain information on the countries.

import  React,{useState} from 'react';
import { Text, TextInput, View, StyleSheet, TouchableWithoutFeedback,Animated,Alert }
from 'react-native';
import {Picker} from '@react-native-community/picker';
const Formulario=(busqueda,guardarbusqueda)=>{
const {pais}=busqueda;
const [animacionboton]=useState(new Animated.Value(1));

const consultarPais=()=>{
  if(pais.trim()===''){
    mostarAlerta();
    return;
  }
  //Consultar API
 guardarconsultar(true);
};

const mostarAlerta=()=>{
    Alert.alert('Error','Debe seleccionar un país'),[{Text:'Entendido'}];
};

const animacionEntrada=()=>{
    Animated.spring(animacionboton,{
        toValue:.9,
        useNativeDriver: true // Add This line
    }).start();
  };

  const animacionSalida=()=>{
     Animated.spring(animacionboton,{
       toValue:1,
       useNativeDriver: true // Add This line
      }).start();
  };

  const estiloAnimacion={
    transform:[{
      scale:animacionboton
    }]
  };


return(

onValueChange={pais=>guardarbusqueda({...busqueda,pais})}

})
export default Formulario;

Pais.js
In this js file a card component to display the information of the selected country.

import React from 'react';
import { StyleSheet, View, Text} from 'react-native';
import { Card } from 'react-native-elements';
const Pais = ({ resultado }) => {
const { capital, name, subregion, region } = resultado;
return (
<Card>
<Card.Title>{name}</Card.Title>
<Card.Divider />
<View style={{ justifyContent: 'center' }}>
<Text>Capital:{capital}</Text>
<Text>Region:{region}</Text>
<Text>Subregion:{subregion}</Text>
</View>
</Card>
);
};
export default Pais;

index.js
In this js file I have placed all the logic of the application.

import React,{useState,useEffect} from 'react';
import {Text,View,StyleSheet,Alert,AppRegistry} from 'react-native';
import Formulario from './src/components/Formulario';
import Pais from './src/components/Pais';
export default function App(){

const [busqueda,guardarbusqueda]=useState({
  pais:'',
});

const [consultar,guardarconsultar]=useState(false);
const [resultado,guardarresultado]=useState({});

useEffect(()=>{
  
  const {pais} = busqueda;
    const consultarPais = async () => {
      if(consultar){
        const url='https://restcountries.eu/rest/v2/alpha/${pais}';
        try{
          const respuesta = await fetch(url);
          const resultado = await respuesta.json();

          guardarresultado(resultado);
          guardarconsultar(false);
        }catch(error){
          mostrarAlerta();
        }
      }
    };
    consultarPais();
},[consultar]);

const mostrarAlerta=()=>{
  Alert.alert('Error','No hay resultado intenta con otra ciudad o país'),[{Text:'Ok'}];
};

return(
<View>
  <View>
  <Formulario
  busqueda={busqueda}
  guardarbusqueda={guardarbusqueda}
 guardarconsultar={guardarconsultar}
  />
<Pais resultado={resultado}/>
  </View>
  </View>
  
);


}
AppRegistry.registerComponent('paises', () => App);
