ClassificationViewModel class

A view model that manages the classification of mosquito images.

This class handles the entire classification workflow including:

  • Image selection from device
  • Local image classification
  • Web-based prediction fallback
  • Observation submission

Methods

addListener(VoidCallback listener) → void
Register a closure to be called when the object changes.
inherited
classifyImage(AppLocalizations localizations) → Future<void>
Classifies the currently selected image using the local model.
dispose() → void
Discards any resources used by the object. After this is called, the object is not in a usable state and should be discarded (calls to addListener will throw after the object is disposed).
inherited
fetchWebPrediction(AppLocalizations localizations) → Future<void>
Fetches a prediction from the web-based classification service.
initModel(AppLocalizations localizations) → Future<void>
Initializes the classification model for local predictions.
noSuchMethod(Invocation invocation) → dynamic
Invoked when a nonexistent method or property is accessed.
inherited
notifyListeners() → void
Call all the registered listeners.
inherited
pickImage(ImageSource source, AppLocalizations localizations) → Future<void>
Picks an image from the specified source for classification.
removeListener(VoidCallback listener) → void
Remove a previously registered closure from the list of closures that are notified when the object changes.
inherited
reset() → void
Resets the view model to its initial state.
setErrorMessage(String? message) → void
Sets an error message to be displayed to the user.
setImageFile(File? file) → void
Sets the current image file and resets related state if needed.
setResult(ClassificationResult? result) → void
Sets the classification result.
setState(ClassificationState state) → void
Updates the current state of the view model.
submitObservation({required ClassificationResult localResult, required WebPredictionResult? webPrediction, required double latitude, required double longitude, required String notes, required AppLocalizations localizations}) → Future<Observation?>
Submits an observation to the server with classification results.
toString() → String
A string representation of this object.

Operators

operator ==(Object other) → bool
The equality operator.
