Main package of color_thief_flutter.

All these functions return null if the parameter is unqualified

getColorFromUrl(String url, [int quality])
returns the base color from the largest cluster, represented as [R,G,B]
getPaletteFromUrl(String url, [int colorCount, int quality])
returns a list that contains the reduced color palette, represented as [[R,G,B]]
getImageFromUrl(String url)
returns the Image from url
getImageFromProvider(ImageProvider imageProvider)
returns the real Image of ImageProvider
getColorFromImage(Image image, [int quality = 10])
returns the base color from the largest cluster, represented as [R,G,B]
getPaletteFromImage(Image image, [int colorCount, int quality])
returns a list that contains the reduced color palette, represented as [[R,G,B]]
parameters

url - Url to image.
imageProvider - ImageProvider.
image - Image that get from getImageFromProvider.
colorCount - Between 2 and 256. The maximum number of colours allowed in the reduced palette.
quality - Between 1 and 10. There is a trade-off between quality and speed. The bigger the number, the faster the palette generation but the greater the likelihood that colors will be missed.
