wu9007 / qrcode_scanner Goto Github PK

Good afternoon

I installed firebase and QR_scan and by themselves they work very well, however when I put in the same application I get the error "Finished with error: Gradle task assembleDebug failed with exit code 1"

I already restarted the IDE and used Flutter Clean but the error persists
can you help me?

 Attribute application@icon value=(@mipmap/launcher_icon) from AndroidManifest.xml:19:9-45
 is also present at [:qrscan] AndroidManifest.xml:22:9-43 value=(@mipmap/ic_launcher).

after adding the plugin I keep getting this error whenever I run my app...

The simples action to give-up to scan a QR Code cause a big issue.
When the user taps on the back arrow or uses the Android back button, the Future function never returns.

The code bellow only reachs the second setState if the scan function actually scan something, other else even user canceling the scanner the function never returns;

setState(() {
     _scanning = true;
});
String qrCode = await scanner.scan();
if (qrCode != null)
    print(qrCode);
setState(() {
    _scanning = false;
});

Please make for landscape mode.

If scanner wrap in widget it will be awesome.

When calling String barcode = await scanner.scan(); I get this error:

PlatformException (PlatformException(error, Unable to find explicit activity class {hsi.alarm.prevozi/com.shinow.qrscan.SecondActivity}; have you declared this activity in your AndroidManifest.xml?, null))

When calling String cameraScanResult = await scanner.scanPath(imagePath); future newer returns result.

Using latest versions, AndroidX and added required user-permissions. What am I dooing wrong?

i performed flutter upgrade and androidx migration, for that i needed to update buid.gradle version from 3.2.1 as follows

    dependencies {
        classpath 'com.android.tools.build:gradle:3.5.0'
    }

After this, all app worked fine but after String qrText= await scanner.scan();
no qrText is returned, there is no debug/console errors too.

build gradle at 3.2.1 works fine though. can you please fix this for 3.5.0 and adndroidx?

Hey, it looks like you migrated to AndroidX libraries but haven't published an update.
How about to publish an update?

我这边测试发现很可能是因为图片文件编码问题，
因为图片经过 flutter_image_compress类压缩处理后就能识别了。
能否在从相册选择文件后，对他先进行压缩或者编码处理后在进行识别呢

Which barcode standards are supported? I tried scanning this sample image and only QR was red.

Hello, 因为Androidx和Android support库不能共存问题导致不能直接引用插件使用，能不能把插件 Migrate to AndroidX，不然只能修改了在本地引用了。

I'm trying this package with your example in the project.
I can succeed scan a barcord on Android device.
But on ipod touch, I've stacked to scan with following error:

Do you have any suggestions about this? Thank you for your kindly help!

How can I disable/remove the File picker button given in the QRScan screen?
There is no way defined for it.

找了一圈就这个库功能比较完备，但是不支持IOS实在太尴尬了……

试了好多次，都是报com.google.zxing.NotFoundException

在网上查了说是 ZXing 包没有识别出二维码，何时能解决一下呢，急...

我扫描条形码没效果，二维码很快就识别出来了

Is there any way to resize the scan area? I've attempted to edit the second activity xml file, but unsure of what i should change.
Thank you in advance.

MissingPluginException(No implementation found for method scan on channel qr_scan)

如题，设置了
<uses-permission android:name="android.permission.INTERNET"/> <uses-permission android:name="android.permission.CAMERA" /> <uses-permission android:name="android.permission.VIBRATE"/>
也没用。

W/CameraBase(13186): An error occurred while connecting to camera 0: Status(-8): '1: validateClientPermissionsLocked:1138: Caller "com.example.motiontrack" (PID 10110, UID 13186) can
not open camera "0" without camera permission'
E/TAG (13186): callBack:
E/TAG (13186): java.lang.RuntimeException: Fail to connect to camera service
E/TAG (13186): at android.hardware.Camera.(Camera.java:574)
E/TAG (13186): at android.hardware.Camera.open(Camera.java:422)

调用scan()打开的扫描界面，左上角的返回按钮和右上角的图片按钮无法有效触发。
在实体机测试时，返回按钮不太好触发（可以稍微加大点？或是调大点，点击有效区）
图片按钮则似乎完全无效。。。

Hi, Can I apply qrcode_scanner just when I'm streaming from camera?.

I need do the following code, for example:

cameraController.startImageStream((CameraImage availableImage) {
    _qrScan(availableImage);
});

I noticed when I execute scan(), this method open the camera. Can I apply just code processing given an CameraImage?

Thank you!

The plugin is worked, but can't support androidX well. Maybe you can update for it.

it is a problem with ZXing, ZBar is able to work it out, after I have tested with ZXing/Zbar directly.

RT，不支持iOS么？

可不可以把二维码框框单独出来，我想自定义它；设计师给的页面，我也好布局。

怎么修改啊
