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.
