createStorageDir(
{required String dirName}) → Future< Directory?> - dirName 文件夹名 category 分类，例如：video，image等等 String path = StorageUtil.getStoragePath(fileName: 'yc.apk', dirName: 'apk');
-
createTempDir(
{required String dirName}) → Future< Directory?> - 创建临时目录 dirName 文件夹名 String path = StorageUtil.createTempDir( dirName: 'image');

getStoragePath(
{required String fileName, required String dirName}) → Future< String?> - fileName 文件名 dirName 文件夹名
-
getTempPath(
{required String fileName, required String dirName}) → Future< String?> - 获取设备上临时目录的路径，该目录没有备份，适合存储下载文件的缓存。 fileName 文件名 dirName 文件夹名 String path = StorageUtil.getTempPath(fileName: 'demo.png', dirName: 'image');
