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	-

rounded	boolean	Round the image into a circle	false
enableLiveTextInteraction	boolean	Enables Live Text interaction with the image (iOS 16+ only)	false
allowHardware	boolean	Setting this to false will reduce performance on API 26 and above. Only disable this if necessary. Coil's docs (Android only)	true
format	string	Specify the format for special image, e.g. svg, gif and apng. In general, TurboImage will determine the decoder automatically.	-
onStart	Function	Gets called when the request is started.	-
onProgress	Function	Gets called when the request progress is updated.	-
onSuccess	Function	Gets called when the requests finished successfully.	-
onFailure	Function	Gets called when the requests fails.	-
onCompletion	Function	Gets called when the request is completed.	-
