由于 Google Play 的原因，我必须将我的一个旧项目更新到最新的 expo 版本（确切地说是版本 43.0.0）。这个想法是让应用程序扫描二维码并简单地处理数据。但是，expo-barcode-scanner 只能工作一次，之后我需要关闭并再次打开应用程序才能工作。有没有人遇到过这个问题并且（或）知道如何解决它？下面是我的代码：
{escaneando ? (
<BarCodeScanner
barCodeTypes={[
BarCodeScanner.Constants.BarCodeType.ean13,
BarCodeScanner.Constants.BarCodeType.ean8,
BarCodeScanner.Constants.BarCodeType.upc_a,
BarCodeScanner.Constants.BarCodeType.upc_e,
]}
onBarCodeScanned={this.handleBarCode.bind(this)}
style={[StyleSheet.absoluteFillObject, styles.barscan]}
/>
) : null}
