implementation 'com.github.bumptech.glide:glide:4.11.0'
// CameraX core library using camera2 implementation
def camerax_version = "1.0.0"

implementation "androidx.camera:camera-lifecycle:${camerax_version}"
// CameraX View class
implementation 'androidx.camera:camera-view:1.0.0-alpha28'
enable databinging in project
