use component in the scene,and I pop it .some thing happened.

I just had the same issue.

Apparently it only happens if I use InteractionManager to render a placeholder (to finish the navigation animation) before the actual scanner is rendered

@Cocoon-break 我也遇到此问题，现在你是如何解决的？

[liuyimx]

@ncnlinh it's not work for me, i remove all 'InteractionManager' use.

@Cocoon-break 解决了吗？

[michalkow]

I have the same problem. I do not use InteractionManager.

Same behaviour here when using InteractionManager to render a placeholder for the scanner.

"react-native": "^0.30.0" "react-native-barcodescanner": "^3.1.1"

When I changed the camera view not full screen, this bug never show again.

This is not perfect but useful method.

[someok]

use marginHorizontal: 1 fix the black screen problem.

<BarcodeScanner
                        ref={view => this.scanner = view}
                        onBarCodeRead={this._onBarCodeRead}
                        style={styles.scanner}
                    />

scanner: {
        flex: 1,

        // 上下留个边， 否则在小米下返回的时候会出现底部黑边
        marginHorizontal: 1,
    }

@someok Your solution works for me. I have no idea how you figured that out, but kudos to you sir!

<View style={{flex:1}}>
    <BarcodeScanner
        onBarCodeRead={this._onBarCodeRead}
        style={{flex:1}}
        torchMode={'off'}
        cameraType={'back'}/>
</View> 

fixed width wrap a view and style={{ flex: 1}}
