Image. class. An image buffer where pixels are encoded into 32-bit unsigned ints (Uint32). Pixels are stored in 32-bit unsigned integers in #AARRGGBB format. This is to be consistent with the Flutter image data. You can use getBytes to access the pixel data at the byte (channel) level, optionally providing the format to get the image data as Fetches an image from an AssetBundle, having determined the exact image to use based on the context.. Given a main asset and a set of variants, AssetImage chooses the most appropriate asset for the current context, based on the device pixel ratio and size given in the configuration passed to resolve.. To show a specific image from a bundle without any asset resolution, use an. centerSlice. property. The center slice for a nine-patch image. The region of the image inside the center slice will be stretched both horizontally and vertically to fit the image into its destination. The region of the image above and below the center slice will be stretched only horizontally and the region of the image to the left and right. The image classes referenced are from the Flutter image class. The docs are here. The constructors that you listed aren't meant for converting between different image types. They are different builders for specific types of images. The Image.from() static method that you referenced is actually called a named constructor
