Vyuh Document

Loading and persistence ​

DocumentEditorController.fromSource resolves a DocumentSource and then builds the controller. Saving is yours: read controller.document and store its JSON wherever your app keeps data.

Load and save a document A DocumentSource is a document, JSON, bytes with a decoder, a URI with a loader, a callback or a stream. DocumentEditorController.fromSource resolves the source and then builds the controller. The host saves controller.document.toJson() to its own storage and loads it again as a source next time. DOCUMENTSOURCE .document(doc) .json · .jsonString .bytes + decoder .uri + loader .loader(callback) .stream(documents) fromSource resolves the source, then builds the controller Controller document document.toJson() Your storage owned by your app next session
Load from a source, save to your storage
dart
import 'package:vyuh_document_editor/vyuh_document_editor.dart';

Future<DocumentEditorController> loadNote(String savedJson) {
  return DocumentEditorController.fromSource(
    source: DocumentSource.jsonString(savedJson),
    extensions: DocumentExtension.richText,
    schema: DocumentSchemaPolicy.richText(),
  );
}

// Dispose the returned controller when its owning widget is disposed.
// Capture controller.toJsonString() when saving; storage is host-owned.

Save a snapshot ​

controller.document.toJson() (or toJsonString()) is the value to store. Your app owns authentication, storage, autosave and conflicts.

Keep one controller for the editing session and dispose it with its widget.

Replace or stream ​

replaceDocument starts a new session. When a stream emits, your app decides whether that is a replacement or a collaborative change.

Files and resources ​

Byte sources take your decoder; URI sources take your loader. Fonts and image bytes are separate resources from the document JSON.
