PipelineOwner constructor

PipelineOwner({
  1. VoidCallback? onNeedVisualUpdate,
  2. VoidCallback? onSemanticsOwnerCreated,
  3. SemanticsUpdateCallback? onSemanticsUpdate,
  4. VoidCallback? onSemanticsOwnerDisposed,
})

Creates a pipeline owner.

Typically created by the binding (e.g., RendererBinding), but can be created separately from the binding to drive off-screen render objects through the rendering pipeline.

Implementation

PipelineOwner({
  this.onNeedVisualUpdate,
  this.onSemanticsOwnerCreated,
  this.onSemanticsUpdate,
  this.onSemanticsOwnerDisposed,
}) {
  assert(debugMaybeDispatchCreated('rendering', 'PipelineOwner', this));
}
