ModelFileSystemManager class
Unified file system operations for model management (Mobile only)
This class delegates filename utilities to FileNameUtils for platform-agnostic string operations, and provides mobile-specific file system operations.

Static Methods
-
cleanupFailedDownload(
ModelSpec spec) → Future< void> - Cleans up failed download files for a model specification
-
cleanupOrphanedFiles(
{required List< String> protectedFiles, List<String> ? supportedExtensions, bool enableResumeDetection = true}) → Future<int> - Cleans up orphaned files
-
deleteModelFile(
String filename) → Future< void> - Safely deletes a model file
-
ensureDirectoryExists(
String dirPath) → Future< void> - Ensures a directory exists, creating it if necessary
-
getBaseName(
String filename) → String - Removes all supported extensions from filename (delegates to FileNameUtils)
-
getCorrectedPath(
String originalPath, String filename) → String - Corrects Android path from /data/user/0/ to /data/data/ for proper file access Uses path.join() for cross-platform path separator handling
-
getFileSize(
String filePath) → Future< int> - Gets file size in bytes, returns 0 if file doesn't exist
-
getMinimumSize(
String extension) → int - Gets minimum file size based on extension (delegates to FileNameUtils)
-
getModelFilePath(
String filename) → Future< String> - Gets the full file path for a model file.
-
getOrphanedFiles(
{List< String> ? protectedFiles, List<String> ? supportedExtensions}) → Future<List< OrphanedFileInfo> > - Get information about orphaned files without deleting them
-
getStorageInfo(
{List< String> ? protectedFiles}) → Future<StorageStats> - Get storage statistics
-
isFileValid(
String filePath, {int minSizeBytes = _defaultMinSizeBytes}) → Future< bool> - Validates if a file exists and meets minimum size requirements
-
isSmallFile(
String extension) → bool - Checks if file extension requires smaller minimum size (delegates to FileNameUtils)
-
validateModelFiles(
ModelSpec spec) → Future< bool> - Validates all files in a model specification
Constants
-
smallFileExtensions
→ const List<
String> - Small file extensions (configs, tokenizers) - use smaller minimum size
-
supportedExtensions
→ const List<
String> - Supported model file extensions (delegates to FileNameUtils)
