Reactjs 让expo camera ref开始在功能组件中录制视频

我正在试着让世博会摄像机录制视频。但是，我得到一个错误：

[TypeError: camera.recordAsync is not a function. (In ‘camera.recordAsync()’, ‘camera.recordAsync’ is undefined)]

这是执行：

<Camera 
                style={{ flex: 1 }} 
                type={type}
                ref={camera}
            >
                <View
                style={{
                    flex: 1,
                    backgroundColor: 'transparent',
                    flexDirection: 'row',
                }}>
                <View style={{ alignSelf: 'flex-end', alignItems: 'center', padding: 20, flexDirection: 'row', justifyContent: 'space-between', width: '100%'}}>
                    <MaterialIcons name="video-library" onPress={pickVideo} color={"#eee"} size={45}/>     
                    <RecordingIcon />    
                    <Ionicons name="ios-reverse-camera" onPress={setCameraType} color={"#eee"} size={45}/>                     
                </View>
                </View>
            </Camera>

但是，由于顶部的错误，这两种方法都不起作用：

async function record(){
        console.log("record", camera); 
        if(camera){
            let recording = await camera.recordAsync(); 
        }
    }

    async function stopRecording(){
        console.log("stop recording", camera); 
        if(camera){
            let stopRecording = await camera.stopRecording(); 
        }
    }

这就是我初始化相机参考的方式

let camera = useRef(null);

非常感谢任何人帮助解决此错误。我也尝试过使用camera.current.recordAsync（）和camera.current.stopRecording（），但得到了相同的错误。

使用camera.current

async function record(){
    console.log("record", camera); 
    if(camera){
        let recording = await camera.current.recordAsync(); 
    }
}
async function stopRecording(){
   console.log("stop recording", camera); 
   if(camera){
       let stopRecording = await camera.current.stopRecording(); 
   }
}

不确定是否已解决此问题，但您是否考虑过针对ref的摄影机组件执行类似{setCamera（ref）；}}>

let camera = useRef(null);

async function record(){
    console.log("record", camera); 
    if(camera){
        let recording = await camera.current.recordAsync(); 
    }
}
async function stopRecording(){
   console.log("stop recording", camera); 
   if(camera){
       let stopRecording = await camera.current.stopRecording(); 
   }
}
