TtsBundleFile class

One file of a TTS model bundle. filename is namespaced by the owning TtsModelType (every bundle member — including the .tflite graphs — since a TTS bundle has no single distinguished "model" file the way Inference/Embedding/STT specs do). prefsKey stays the PLAIN manifest basename — NOT the namespaced filename — because flutter_gemma_speech's TtsModelProfile (e.g. configFile = 'config.json') and TtsCore/MatchaTextFrontend look bundle paths up by that plain name (paths[profile.configFile]); decoupling keeps that cross-package contract intact while the on-disk/repository identity is namespaced.

Constructors

TtsBundleFile({required ModelSource source, required String filename, required String plainFilename})

TtsBundleFile.fromSource(ModelSource source, {required String modelId})

Creates TtsBundleFile from ModelSource, namespaced by modelId — in practice the owning TtsModelType's name (matcha/kokoro/supertonic).

factory

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?

Optional per-file minimum size (bytes) for the download-corruption check. Null → the validator falls back to the extension heuristic (FileNameUtils.getMinimumSize). Override for files whose real size is legitimately below the 1 MB default (e.g. a small embedding blob).

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.
