Properties

Name	Type	Description	Default
`source`	`Source`	(Required) an object containing a `uri` string	-
`style`	`ImageStyle`	Styles to be applied to the image.	-
`placeholder`	`Placeholder`	show placeholder while loading	-
`cachePolicy`	`CachePolicy`	Determines how to cache the image	urlCache
`resizeMode`	`String`	Resize the image with one of the options: `contain` `cover` `stretch` `center`	contain
`indicator`	`object`	`style`: `medium`(default) or `large`. `color`: `number / ColorValue`	-
`fadeDuration`	`number`	The transition duration of the image. Note: To avoid flicking, it will be set to 0 when a placeholder is provided	300(iOS) / 100(Android)
`resize`	`number`	Scales an image to the given width preserving aspect ratio	-
`blur`	`number`	The blur radius of the blur filter added to the image	-
`monochrome`	`number / ColorValue`	The color applied to the image. note: For iOS and Android Q+, it works with any color. For Android Q-, it only supports grayscale	-
`tint`	`number / ColorValue`	The color is applied to every non-transparent pixel, causing the image’s shape to adopt that color. This effect is not applied to placeholders	-
