print(palette); // [[R,G,B]]
});
getImageFromUrl('url/to/image').then((image) {
print(image); // Image
});

color_thief_flutter.dart
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 fromgetImageFromProvider
.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.
utils.dart
Tools for format colors.
May cause loss of significance
