无法解决 React Native Camera MLKit 依赖项

Question

My app builds fine on Android Studio, it runs fine with react-native run-android but when I try to generate the .apk it fails with ./gradlew assembleRelease command. I get the following error.

Error Message

* What went wrong:
Could not determine the dependencies of task ':react-native-camera:compileMlkitReleaseAidl'.
> Could not resolve all task dependencies for configuration ':react-native-camera:mlkitReleaseCompileClasspath'.
   > Could not find com.google.firebase:firebase-ml-vision:12.0.1.

   > Could not find com.google.firebase:firebase-ml-vision-face-model:12.0.1.

         project :react-native-camera

package.json

    "react": "16.8.3",
    "react-native": "0.59.10",
    "react-native-camera": "^3.7.1",
    "react-native-image-picker": "^0.28.1",
    "react-native-qrcode-scanner": "^1.2.3",

gradle properties

classpath('com.android.tools.build:gradle:3.4.0') // FROM android/gradle.build
distributionUrl=https\://services.gradle.org/distributions/gradle-5.4.1-all.zip // FROM gradle-wrapper.properties

I have followed the installation instructions here and followed GitHub links here and here .

All have the same solution which I have completed, ie adding;

android/app/build.gradle

android {
  defaultConfig {
    missingDimensionStrategy 'react-native-camera', 'general'
  }
}

Note

The issue is because android is looking for mlkit dependencies even when I have not opted for them. I think this is happening because I use react-native-image-picker and react-native-qrcode-scanner one of these packages is looking mlkit dependencies. But I don't know how to debug and fix it.

Be sure that in the android/app/build.gradle you added this

missingDimensionStrategy 'react-native-camera', 'general' in *defaultConfig*

Then check your internet connectivity is good while building. If it doesn't work, use npm run release
