demo code:

// create ImageProvider
BufferImage bufferImage = BufferImage(100, 100);
for (int i = 0; i < 100; i++) {
    for (int j = 0; j < 100; j++) {
    bufferImage.setColor(
        i, j, Colors.primaries[(i * 100 + j) % Colors.primaries.length]);
    }
}
image = RgbaImage.fromBufferImage(bufferImage, scale: 1);
bufferImage.resize(2);
scaleImage = RgbaImage.fromBufferImage(bufferImage, scale: 1);


// display Image
Center(
    child: Column(
        mainAxisAlignment: MainAxisAlignment.spaceAround,
        children: <Widget>[
        Image(
            image: image,

        Image(
            image: scaleImage,
        ),
        ],
