java.lang.RuntimeException: Unable to start activity ComponentInfo{com.mypackage/com.scanlibrary.ScanActivity}: java.lang.IllegalArgumentException: Couldn't find meta-data for provider with authority com.scanlibrary.provider

Hi, I've encountered an issue while using this package.
What I wanted is to add a document scanner feature to my app using this code below:

try {
      scannedDoc = await DocumentScannerFlutter.launch(context,
          source: ScannerFileSource.CAMERA);
    } catch (e) {
      print(e);
    }

After I trigger that method, my app crashed and this is the stack trace:

Thanks in advance.

Did you solve this issue with the provider tag: #9 ?

[aiman5252]

No, I need to use that provider tag to build the app, but it didn't solve this issue.

[kalloszsolty]

As far as I understand this is beacuse of the tools:replace="android:authorities"
What build error do you get if you remove the provider from the Manifest?
For me it builds, but if I try to use the same library in a sibling app of mine, I get the error:
[INSTALL_FAILED_CONFLICTING_PROVIDER: Scanning Failed.: Can't install because provider name com.scanlibrary.provider is already used

[rajada1]

this #9 solved my problem
