Finally I found the solution

1. make sure your dependencies in android/app/build.gradle:
   dependecies {
   //....

   implementation 'com.google.firebase:firebase-core:+'

   implementation 'com.google.firebase:firebase-ml-vision:+'
   //......
   }

2. add following to android/build.gradle:

allprojects {
repositories {
//start here
configurations.all {
resolutionStrategy.eachDependency { DependencyResolveDetails details ->
def requested = details.requested
if (requested.group == 'com.google.android.gms') {
details.useVersion '+'
}
if (requested.group == 'com.google.firebase') {
details.useVersion '+'
}
}
}
//end
jcenter()
maven {
url "https://maven.google.com"
}
}
}
