MethodChannelFlutterLive2d class

Default platform implementation of FlutterLive2dPlatform, routing every call through the flutter_live2d MethodChannel.

Behavioral notes that apply across calls:

  • viewId identifies the native view created when a Live2DView widget mounts. The native side uses it to look up the per-view state (model, GL surface, …) and returns a VIEW_NOT_FOUND error if the view has already been disposed.
  • Native errors are surfaced as PlatformExceptions with the codes listed in the Live2DException documentation. The Dart-side Live2DViewController normalizes them into Live2DException.
Inheritance

Properties

hashCode → int
The hash code for this object.
no setterinherited
methodChannel → MethodChannel
Underlying MethodChannel. Exposed for tests so they can install a mock handler; treat it as private otherwise.
final
runtimeType → Type
A representation of the runtime type of the object.
no setterinherited

Methods

getPlatformVersion() → Future<String?>
Returns the host platform's version string (e.g. "Android 14"). Used as a smoke test that the channel is wired up.
override
loadModel({required int viewId, required String modelDir, required String modelFileName}) → Future<bool>
Loads a Live2D model into the native view identified by viewId.
override
noSuchMethod(Invocation invocation) → dynamic
Invoked when a nonexistent method or property is accessed.
inherited
setExpression({required int viewId, required int index}) → Future<void>
Switches the active expression on viewId to the one at index in the model's expression list (0-based).
override
setMotionSpeed({required int viewId, required double speed}) → Future<void>
Sets the motion playback speed multiplier for viewId.
override
setParameter({required int viewId, required String parameterId, required double value}) → Future<void>
Sets the model parameter parameterId on viewId to value.
override
setRenderingPaused({required int viewId, required bool paused}) → Future<void>
Pauses or resumes the GL render loop for viewId.
override
startMotion({required int viewId, required String group, required int index, int priority = 2}) → Future<void>
Plays a motion on viewId.
override
toString() → String
A string representation of this object.
inherited
unloadModel({required int viewId}) → Future<void>
Unloads the model currently bound to viewId and frees its native resources. No-op if no model is loaded.
override

Operators

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