Compose Neon 
A small Jetpack Compose library that provides Compose support for different image loading libraries.
Setup
Integrating with Glide:
To add Glide support, import the Neon Glide library:
implementation 'com.husseinala.neon:glide:0.1.6'Provide a Glide RequestManager instance to your root Compose tree:
class MainActivity : AppCompatActivity() {
override fun onCreate(savedInstanceState: Bundle?) {
super.onCreate(savedInstanceState)
// Create a new `RequestManager` instance or re-use your existing instance
val glide = Glide.with(applicationContext)
setContent { GlideApp(glide) }
}
}
@Composable
fun GlideApp(requestManager: RequestManager) {
ProvideGlideLoader(requestManager) {
SampleScreen()
}
}Integrating with Picasso:
To add Picasso support, import the Neon Picasso library:
implementation 'com.husseinala.neon:picasso:0.1.6'Provide a Picasso instance to your root Compose tree:
class MainActivity : AppCompatActivity() {
override fun onCreate(savedInstanceState: Bundle?) {
super.onCreate(savedInstanceState)
// Create a new `Picasso` instance or re-use your existing instance
val picasso = Picasso.Builder(applicationContext).build()
setContent { PicassoApp(picasso) }
}
}
@Composable
fun PicassoApp(picasso: Picasso) {
ProvidePicassoLoader(picasso) {
SampleScreen()
}
}Usage
After providing your image loader, you can simply use the Neon Composable function to directly load images:
@Composable
fun UserListItem(user: User) {
Column {
Neon(
url = user.profileImage,
// Optional: Any Transformations to be applied to the image, such as rounded corners or scale type.
transformation = Transformation.centerCrop(),
// Optional: Any Modifiers to be applied to the image container, such as view size or paddings.
modifier = Modifier.fillMaxWidth().aspectRatio(1.7f).padding(horizontal = 16.dp, vertical = 8.dp),
onLoading = { /* Optional: the widget to be displayed while the image is being downloaded */ },
onError = { /* Optional: the widget to be displayed if an error occurs */ }
)
Text(text = user.name)
}
