react-native-google-places-autocomplete给予它一个值,而不仅仅是默认值

我有一个工作<TextInput>

<TextInput
      placeholder="Location"
      value={props.locationInput.toString()}
      onChangeText={location => props.updateLocationInput(location)}
    />

字符串
props.locationInput最初是'',但一旦应用程序启动,就会触发几个异步函数并获取用户的当前位置,这些位置填充props.locationInput(在redux商店中)。这意味着上面的<TextInput>在到达时显示用户的当前位置。我想基本上就像上面一样,但是使用react-native-google-places-autocomplete
react-native-google-places-autocomplete使用props.locationInput值进行初始化。它有一个getDefaultValue属性,例如getDefaultValue={() => props.locationInput.toString()},但是当props.locationInput改变时,它不会改变,所以它永远不会显示用户的当前位置,因为在初始化时没有设置。如何在props.locationInput更改时更新react-native-google-places-autocomplete
可能我认为我可能需要不渲染它,直到用户的当前位置进来,但这真的很混乱。
编辑:还考虑不使用插件,而是调用Google Places API。

游戏后期,但有一个名为setAddressText的函数。
范例:

setLocation(text) {
  this.placesRef && this.placesRef.setAddressText(text)
}
...
<GooglePlacesAutocomplete
ref={ref => {this.placesRef = ref}}
...
/>

使用react函数钩子

<GooglePlacesAutocomplete
          ...
          ref={ref => {
            ref?.setAddressText('123 myDefault Street, mycity')
          }}
        />

在GooglePlaceAutocomplete组件上,必须使用onPress事件来获取值。下面是一个示例:

<GooglePlacesAutocomplete
                placeholder='Event Location'
                minLength={2} // minimum length of text to search
                autoFocus={false}
                // Can be left out for default return key https://facebook.github.io/react-native/docs/textinput.html#returnkeytype
                listViewDisplayed='auto'    // true/false/undefined
                fetchDetails={true}
                renderDescription={row => row.description} // custom description render
                onPress={(data, details = null) => {
            // 'details' is provided when fetchDetails = true
            this.setState(
              {
                address: data.description, // selected address
                coordinates: `${details.geometry.location.lat},${details.geometry.location.lng}` // selected coordinates
              }
            );
          }}
                textInputProps={{
                  onChangeText: (text) => { console.warn(text) }
                }}
                getDefaultValue={() => ''}

                query={{
                  // available options: https://developers.google.com/places/web-service/autocomplete
                  key: 'XXXXXXXXXXXXXXZXZXXXXXXX',
                  language: 'en', // language of the results
                  types: 'geocode' // default: 'geocode'
                }}

                styles={{
                  textInputContainer: {
                    backgroundColor: 'rgba(0,0,0,0)',

                  description: {
                    fontWeight: 'bold',
                  },
                  textInput: {
                  marginLeft: 22,
                  marginRight: 0,
                  height: 38,

                value={props.location}
                onChangeText={props.onLocationChange}
                renderLeftButton={()  => <Text style={{ marginTop: 12, marginLeft:16, fontSize: 18 }}> Location </Text>}
                nearbyPlacesAPI='GooglePlacesSearch' // Which API to use: GoogleReverseGeocoding or GooglePlacesSearch
                GoogleReverseGeocodingQuery={{
