There are two ways to compress images.

example:

jpg:desPath = await CompressImage.compressJPG(File(srcPath), "/storage/emulated/0/XXX/", maxMemorySize: 2 * 1024 * 1024, maxFileSize: 200 * 1024);

png:desPath = await CompressImage.compressPNG(File(srcPath), "/storage/emulated/0/XXX/", maxMemorySize: 2 * 1024 * 1024, compressLevel: PNGCompressLevel.BEST_COMPRESSION);
