To enhance the scanning functionality, you can implement a state that updates once the code is scanned. This state can be used to alter the prop value `scanBarcode` or replace the `` component with another element displaying the content of the scanned code.
For instance, in Example 1, the barcode scanning stops after detection until the state is set back to true:
const [doScanBarcode, setDoScanBarcode] = useState(true);//initialize state
.
.
.
<Camera
showFrame={true}
laserColor={Colors.green}
frameColor="white"
onReadCode={(event: any) => {
setDoScanBarcode(false);//update state here
console.log("Event:", event?.nativeEvent.codeStringValue)
}}
scanBarcode={doScanBarcode}//utilize state here
style={{flex: 1}}
/>
In Example 2, the rendering changes based on whether the code has been scanned. Once scanned, the camera closes and displays a message confirming the scan:
const [renderScanner, setRenderScanner] = useState(true);//establish state
.
.
.
<>
{
renderScanner ?
<Camera
showFrame={true}
laserColor={Colors.green}
frameColor="white"
onReadCode={(event: any) => {
setRenderScanner(false);//update state here
console.log("Event:", event?.nativeEvent.codeStringValue)
}}
scanBarcode={true}
style={{flex: 1}}
/> :
<Text>The code has been scanned.</Text>
}
</>
Remember to format it accordingly and import the required dependencies for seamless integration.
May your coding endeavors be successful!
