DirectoryBundleFile class

One file of a DIRECTORY inference model (ORT-GenAI): the model is a set of files that must live together in a per-model subdirectory with their BARE leaf names (genai_config.json references its siblings by bare name and the native loader is handed the directory). filename is the EXPLICIT install identity <modelId>/<bareLeaf> (a real subpath) — NEVER derived from source, so the on-disk id and the repository key always agree (a FileSource-derived basename would drop the subdir and break the repo lookup on every restore). The PRIMARY file (genai_config.json) uses PreferencesKeys.installedModelFileName as its prefsKey so the persist-identity + modelFilePaths.values.first both find it; siblings use their bare leaf name so each maps to a distinct getModelFilePaths entry.

Constructors

DirectoryBundleFile.member({required String modelId, required String bareName, required String primaryName, required ModelSource source})

Builds one bundle member from its modelId (the subdirectory), its BARE leaf bareName, and the bundle's primaryName (the file the engine loads from — for ORT-GenAI, genai_config.json). The primary gets PreferencesKeys.installedModelFileName as its key so persist-identity and getModelFilePaths.values.first find it; every sibling keys on its bare name so each maps to a distinct path entry. Used by both the install path and the restore path, so the key rule lives in one place.

Properties

extension → String

File extension for validation purposes (with leading dot, e.g., '.model')

no setter, inherited

filename → String

Local filename for this file

no setter, override

hashCode → int

The hash code for this object.

no setter, inherited

isRequired → bool

Whether this file is required for the model to function

no setter, override

minimumSizeBytes → int?

Directory members (.onnx_data, genai_config.json, tokenizer json/vocab) aren't in FileNameUtils.supportedExtensions, so the extension heuristic would wrongly impose the 1 MB default on small config files. We only assert "a non-empty file landed"; real size/sha verification is a follow-up (ResolvedHfFile.sha256/sizeBytes are carried but not yet checked).

no setter, override

prefsKey → String

SharedPreferences key for storing this file's installation status

no setter, override

runtimeType → Type

A representation of the runtime type of the object.

no setter, inherited

source → ModelSource

Source from which this file can be obtained (NEW: type-safe ModelSource)

no setter, override

Methods

noSuchMethod(Invocation invocation) → dynamic

Invoked when a nonexistent method or property is accessed.

inherited

toString() → String

A string representation of this object.

Operators

operator ==(Object other) → bool

The equality operator.
