问无法从React(V6)Firestore获得数据:未定义不是一个函数(接近‘...this._firestore.native.collectionGet.’)

EN

import React, {Component} from 'react';
import { firebase } from '@react-native-firebase/firestore';

export default App extends Component{
  constructor(props) {
    super(props);

    this.getData= this.getData.bind(this)
    this.getData()

    this.state = {};
  }

  async getData() {
    try {
      const querySnapshot = await firebase.firestore()
      .collection('Gyms')
      .get() //error with this

      console.log('Documents', querySnapshot.docs);

    } catch (e) {
      console.log(e);
    }
  }
}
