react-native - React Native：警告：道具类型失败：提供给`MapMarker`的`number`类型的无效道具`coordinate`，预期`object`

问题描述

我正在构建我的第一个应用程序，一个城市指南应用程序。

我对 React Native 还是很陌生，我有一个问题react-native-maps（我认为）。

我正在尝试通过 Axios 查询从我的数据库中获取地图上显示的标记

这是我的 Axios：

import axios from 'axios';

// URL API BASE
const APIURL = 'http://10.22.101.55:5000/api';


// RECUPERATION DES RESTAURANTS
export const getAllRestaurant = (nom, adresse, ville, cp, telephone, email, latitude, longitude ) => axios.get(`${APIURL}/restaurant`, {
    nom: nom,
    adresse: adresse,
    ville: ville,
    cp: cp,
    telephone: telephone,
    email: email,
    latitude: latitude,
    longitude: longitude
});

我必须更改呼叫的 URL，否则会收到网络错误类型错误 (Localhost -> 10.22.101.55)

我调用 Axios 的页面：

import React, { useEffect } from 'react';
import { View, StyleSheet } from 'react-native';
import MapView, { Marker } from 'react-native-maps';

// Récupération des données
import {getAllRestaurant} from '../service/emplacements'

export default function AccueilScreen() {

  // RECUPERATION DES RESTAURANTS
  const [restaurants, setRestaurants] = React.useState([])
  const LesRestaurants = () => [
    getAllRestaurant().then(response => {
      setRestaurants(response.data);
      console.log(response);
    }).catch(err => console.log('API :' + err))
  ]

  // CHARGEMENT DES RESTAURANTS
  useEffect(() => {
    LesRestaurants()
  },[])


  return (
    <View style={styles.container}>
     <MapView
      scrollEnabled={false}
      rotateEnabled={false}
      zoomEnabled={false}
      minZoomLevel={0}
      maxZoomLevel={13}
      style={styles.map}
      region={{
         latitude: 49.4826616,
         longitude: 1.7245633,
         latitudeDelta: 0.015,
         longitudeDelta: 0.0121,
      }}
     >
      {restaurants.map((restaurant) => (
        <Marker
          key={restaurant.id}
          coordinate={restaurant.latitude, restaurant.longitude}
          title={restaurant.nom}
        />
      ))}
    </MapView>
   </View>
  );
}

const styles = StyleSheet.create({
  container: {
    ...StyleSheet.absoluteFillObject,
    height: '100%',
    width: '100%',
    justifyContent: 'flex-end',
    alignItems: 'center',
  },
  map: {
    ...StyleSheet.absoluteFillObject,
  },
 });

这就是我在控制台中得到的：

}

以及控制台中的错误信息+错误显示

警告：道具类型失败：提供给coordinate的道具类型无效，应为。 numberMapMarkerobject

对我来说，错误是因为我给的坐标<Marker/>

提前感谢您的帮助和您的时间！

编辑：错误确实来自坐标，当我手动给出纬度和经度时，一切正常。
