Props

• AsyncImageAnimated:

  animationStyle?: 'fade' | 'shrink' | 'explode',
  delay?: number,
  imageKey?: string,
  placeholderColor?: string,
  placeholderSource?: { uri: string } | number,
  source: { uri: string }, // required
  style: ViewStyle, // height & width required
  

Conditions

• If placeholderSource is set the animationStyle is set to fade. It just looks better.
