react-native-vision-camera: 🐛 App crash using QR scanner (useCodeScanner)

What’s happening?

The app crashes after scanning a QR code and navigate to another screen (using React Native Navigation) The QR code is successfully scanned but when I want to navigate to another page after (inside onCodeScanned callback) and the app sometimes crashes.

If I unmount the <Camera /> component before navigating to another page it also crash, example.

  const [isActive, setIsActive] = React.useState(true);
  const [isMount, setIsMount] = React.useState(true);
  const device = useCameraDevice('back');

  const codeScanner = useCodeScanner({
    codeTypes: ['qr', 'ean-13'],
    onCodeScanned: codes => {
      setIsActive(false);
      setIsMount(false);  // <-- sometimes crash
      props.navigation.navigate('ANOTHER_SCREEN'); // React native navigation
    },
  });

  return isMount ? (
    <Camera
      style={styles.camera}
      device={device}
      isActive={isActive}
      audio={false}
      codeScanner={codeScanner}
    />
  ) : null;

Is this a mistake or am I doing it wrong?

Reproduceable Code

import React, {useEffect} from 'react';
import {StyleSheet, Text} from 'react-native';

import {
  Camera,
  useCameraDevice,
  useCameraPermission,
  useCodeScanner,
} from 'react-native-vision-camera';

export default function VisionScreen(props: any) {
  const {hasPermission, requestPermission} = useCameraPermission();
  const device = useCameraDevice('back');

  useEffect(() => {
    if (!hasPermission) {
      console.log(requestPermission());
    }
  }, [hasPermission, requestPermission]);

  const codeScanner = useCodeScanner({
    codeTypes: ['qr', 'ean-13'],
    onCodeScanned: codes => {
      props.navigation.navigate('ANOTHER_SCREEN'); // <-- crash
    },
  });

  if (device == null || !hasPermission) {
    return <Text>HasPermission False</Text>;
  }

  return (
    <Camera
      style={styles.camera}
      device={device}
      isActive={true}
      audio={false}
      codeScanner={codeScanner}
    />
  );
}
const styles = StyleSheet.create({
  camera: {
    width: 680,
    height: 680,
  },
});

@mrousavy looks like this is it!! it did crash after a couple tries using 3.9.1 and we did not reproduce crashes (so far) with 4.0.0-beta.10. Awesome 🎉! thanks for your time and effort.

Btw, after more testing we found out that the issue was clearly a race condition when an unmount of the component did interrupt an ongoing scan.

Working on a fix for this issue here: https://github.com/mrousavy/react-native-vision-camera/pull/2494 👀

Still in development, so don’t test yet. Long way to go, this is a really complicated issue (as you can see in the changes/Files of that PR)…

mrousavy on Feb 1, 2024

@mrousavy For me it only crashes if the View containing the Camera component is conditionally rendered, i.e. programmatically hidden or set to be visible, if the said container is always visible and never gets hidden it won’t crash.

{isCamVisible ? ( <View> <Camera style={StyleSheet.absoluteFill} device={device} isActive={isCamActive} codeScanner={codeScanner} /> </View> ) : null}

@mrousavy I share you the full adb logcat logs (I exported from Android Studio) and a video of what I was doing. If you need something else let me know.

The code I was using is this (with the version 3.7.0)

import {useFocusEffect} from '@react-navigation/native';
import React, {useCallback, useEffect} from 'react';
import {StyleSheet, Text} from 'react-native';

import {
  Camera,
  useCameraDevice,
  useCameraPermission,
  useCodeScanner,
} from 'react-native-vision-camera';

export default function CamaraScreen(props: any) {
  const [isActive, setIsActive] = React.useState(true);
  const [isMount, setIsMount] = React.useState(true);

  const {hasPermission, requestPermission} = useCameraPermission();
  const device = useCameraDevice('back');

  useFocusEffect(
    useCallback(() => {
      console.log('Camera is mounted');
      setIsMount(true);
      return () => {
        console.log('Camera is unmounted');
        setIsMount(false);
      };
    }, []),
  );

  useEffect(() => {
    if (!hasPermission) {
      console.log(requestPermission());
    }
  }, [hasPermission, requestPermission]);

  const codeScanner = useCodeScanner({
    codeTypes: ['qr', 'ean-13'],
    onCodeScanned: codes => {
      //setIsActive(false);
      console.log(codes[0].value);
      props.navigation.navigate('ANOTHER_SCREEN'); // <-- crash
    },
  });

  if (device == null || !hasPermission) {
    return <Text>HasPermission False</Text>;
  }

  return isMount ? (
    <Camera
      style={styles.camera}
      device={device}
      isActive={isActive}
      audio={false}
      photo={false}
      video={false}
      codeScanner={codeScanner}
    />
  ) : null;
}
const styles = StyleSheet.create({
  camera: {
    width: 680,
    height: 680,
  },
});

@mrousavy For me it only crashes if the View containing the Camera component is conditionally rendered, i.e. programmatically hidden or set to be visible, if the said container is always visible and never gets hidden it won’t crash.

For me the following workaround seems to work out:

I set Camera.isActive to false and wait a few moments before hiding the container

SveBo on Jan 19, 2024

I just released a V4 beta, can you try if that fixes the bugs?

Same stack trace as https://github.com/mrousavy/react-native-vision-camera/issues/2116

@mrousavy For me it only crashes if the View containing the Camera component is conditionally rendered, i.e. programmatically hidden or set to be visible, if the said container is always visible and never gets hidden it won’t crash.

{isCamVisible ? ( <View> <Camera style={StyleSheet.absoluteFill} device={device} isActive={isCamActive} codeScanner={codeScanner} /> </View> ) : null}

Same problem. Quick dirty workaround opacity: 0
