Getting Started

Add the AppFlowy editor Flutter package to your environment.

flutter pub add appflowy_editor
flutter pub get

Creating Your First Editor

Start by creating a new empty AppFlowyEditor object.

final editorState = EditorState.empty(); // an empty state
final editor = AppFlowyEditor(
    editorState: editorState,
);

You can also create an editor from a JSON object in order to configure your initial state. Or you can create an editor from Markdown or Quill Delta.

final json = ...;
final editorState = EditorState(Document.fromJson(data));
final editor = AppFlowyEditor(
    editorState: editorState,
);

Note: The parameters localizationsDelegates need to be assigned in MaterialApp widget

MaterialApp(
    localizationsDelegates: const [
        AppFlowyEditorLocalizations.delegate,
    ]，
);

To get a sense of how the AppFlowy Editor works, run our example:

git clone https://github.com/AppFlowy-IO/appflowy-editor.git
flutter pub get
flutter run
