Storage Kotlin Extensions

Getting Started

To use the Cloud Storage Android SDK with Kotlin Extensions, add the following to your app's build.gradle file:

// See maven.google.com for the latest versions
// This library transitively includes the firebase-storage library
implementation 'com.google.firebase:firebase-storage-ktx:$VERSION'

Features

Get an instance of FirebaseStorage

Kotlin

val storage = FirebaseStorage.getInstance()
val anotherStorage = FirebaseStorage.getInstance(FirebaseApp.getInstance("myApp"))

Kotlin + KTX

val storage = Firebase.storage
val anotherStorage = Firebase.storage(Firebase.app("myApp"))

Get the FirebaseStorage for a custom storage bucket url

Kotlin

val storage = FirebaseStorage.getInstance("gs://my-custom-bucket")
val anotherStorage = FirebaseStorage.getInstance(FirebaseApp.getInstance("myApp"), "gs://my-custom-bucket")

Kotlin + KTX

val storage = Firebase.storage("gs://my-custom-bucket")
val anotherStorage = Firebase.storage(Firebase.app("myApp"), "gs://my-custom-bucket")

Create file metadata

Kotlin

val metadata = StorageMetadata.Builder()
        .setContentType("image/jpg")
        .setContentDisposition("attachment")
        .setCustomMetadata("location", "Maputo, MOZ")
        .build()

Kotlin + KTX

val metadata = storageMetadata {
    contentType = "image/jpg"
    contentDisposition = "attachment"
    setCustomMetadata("location", "Maputo, MOZ")
}
