FlutterQuill is a rich text editor and a Quill component for Flutter.

This library is a WYSIWYG editor built for the modern mobile platform, with web compatibility under development. Check out our Youtube Playlist to take a detailed walkthrough of the code base. You can join our Slack Group for discussion.

Demo App: https://bulletjournal.us/home/index.html

Pub: https://pub.dev/packages/flutter_quill

Usage #

See the example directory for a minimal example of how to use FlutterQuill. You typically just need to instantiate a controller:

QuillController _controller = QuillController.basic();

and then embed the toolbar and the editor, within your app. For example:

Column(
  children: [
    QuillToolbar.basic(controller: _controller),
    Expanded(
      child: Container(
        child: QuillEditor.basic(
          controller: _controller,
          readOnly: false, // true for view only mode
        ),
      ),
    )
  ],
)

Check out Sample Page for advanced usage.

Input / Output #

This library uses Quill as an internal data format.

  • Use _controller.document.toDelta() to extract the deltas.
  • Use _controller.document.toPlainText() to extract plain text.

FlutterQuill provides some JSON serialisation support, so that you can save and open documents. To save a document as JSON, do something like the following:

var json = jsonEncode(_controller.document.toDelta().toJson());

You can then write this to storage.

To open a FlutterQuill editor with an existing JSON representation that you've previously stored, you can do something like this:

var myJSON = jsonDecode(incomingJSONText);
_controller = QuillController(
          document: Document.fromJson(myJSON),
          selection: TextSelection.collapsed(offset: 0));

Configuration #

The QuillToolbar class lets you customise which formatting options are available. Sample Page provides sample code for advanced usage and configuration.

Web #

For web development, use flutter config --enable-web for flutter or use ReactQuill for React.

It is required to provide EmbedBuilder, e.g. defaultEmbedBuilderWeb. Also it is required to provide webImagePickImpl, e.g. Sample Page.

Desktop #

It is required to provide filePickImpl for toolbar image button, e.g. Sample Page.

Custom Size Image for Mobile #

Define mobileWidth, mobileHeight, mobileMargin, mobileAlignment as follows:

{
      "insert": {
         "image": "https://user-images.githubusercontent.com/122956/72955931-ccc07900-3d52-11ea-89b1-d468a6e2aa2b.png"
      },
      "attributes":{
         "style":"mobileWidth: 50; mobileHeight: 50; mobileMargin: 10; mobileAlignment: topLeft"
      }
}

Translation of toolbar #

The package offers translations for the quill toolbar, it will follow the system locale unless you set your own locale with:

QuillToolbar(locale: Locale('fr'), ...)

Currently, translations are available for these locales:
