## Getting Started
Add the AppFlowy editor [Flutter package](https://docs.flutter.dev/development/packages-and-plugins/using-packages) to your environment.
```shell
flutter pub add appflowy_editor
flutter pub get
```
## Creating Your First Editor
Start by creating a new empty AppFlowyEditor object.
```dart
final editorState = EditorState.blank(withInitialText: true); // with an empty paragraph
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](https://github.com/AppFlowy-IO/appflowy-editor/blob/main/documentation/importing.md).
```dart
final json = jsonDecode('YOUR INPUT JSON STRING');
final editorState = EditorState(document: Document.fromJson(json));
final editor = AppFlowyEditor(
editorState: editorState,
);
```
> Note: The parameters `localizationsDelegates` need to be assigned in MaterialApp widget
```dart
MaterialApp(
localizationsDelegates: const [
AppFlowyEditorLocalizations.delegate,
]，
);
```
To get a sense of how the AppFlowy Editor works, run our example:
```shell
git clone https://github.com/AppFlowy-IO/appflowy-editor.git
flutter pub get
flutter run
```
