There are two ways to compress images. #

2、compress image. optional params in the jpg and level in the png ensure the size of image's file is less than given size #

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); #
