 Note: `AnimatedImage` some methods like `.transition`, `.indicator` and `.aspectRatio` have the same naming as `SwiftUI.View` protocol methods. But the args receive the different type. This is because `AnimatedImage` supports to be used with UIKit/AppKit component and animation. If you find ambiguity, use full type declaration instead of the dot expression syntax.
