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/qwen3/inflect/…).factory
Properties
- extension → String
-
File extension for validation purposes (with leading dot, e.g., '.model')
no setterinherited
- filename → String
-
Local filename for this file
no setteroverride
- hashCode → int
-
The hash code for this object.
no setterinherited
- isRequired → bool
-
Whether this file is required for the model to function
no setteroverride
- 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 setteroverride - prefsKey → String
-
SharedPreferences key for storing this file's installation status
no setteroverride
- runtimeType → Type
-
A representation of the runtime type of the object.
no setterinherited
- source → ModelSource
-
Source from which this file can be obtained (NEW: type-safe ModelSource)
no setteroverride
