FlutterQuill is a rich text editor and a Quill component for Flutter.
This library is a WYSIWYG (What You See Is What You Get) editor built for the modern Android, iOS, web and desktop platforms. Check out our Youtube Playlist or Code Introduction to take a detailed walkthrough of the code base. You can join our Slack Group for discussion.

The flutter_quill package uses the following plugins:
url_launcherto open links.device_info_plusto view info about the current device.flutter_keyboard_visibilityto listen for keyboard visibility changes.
All of them don't require any platform-specific setup.
Note
Starting from Flutter Quill 9.4.x, super_clipboard has been moved
to FlutterQuill Extensions, to use rich text pasting, support pasting images, and gif files from external apps or websites, take a look
at flutter_quill_extensions Readme.
Instantiate a controller:
QuillController _controller = QuillController.basic();Use the QuillEditor, and QuillSimpleToolbar widgets,
and attach the QuillController to them:
QuillSimpleToolbar(
controller: _controller,
configurations: const QuillSimpleToolbarConfigurations(),
),
Expanded(
child: QuillEditor.basic(
controller: _controller,
configurations: const QuillEditorConfigurations(),
),
)Dispose of the QuillController in the dispose method:
@override
void dispose() {
_controller.dispose();
super.dispose();
}Check out Sample Page for more advanced usage.
Starting from version 8.0.0
We have added Migration Guide for migration from different versions
This library uses Quill Delta to represent the document content. The Delta format is a compact and versatile way to describe document changes. It consists of a series of operations, each representing an insertion, deletion, or formatting change within the document.
Don’t be confused by its name Delta—Deltas represents both documents and changes to documents. If you think of Deltas as the instructions for going from one document to another, the way Deltas represents a document is by expressing the instructions starting from an empty document.
- Use
_controller.document.toDelta()to extract the deltas. - Use
_controller.document.toPlainText()to extract plain text.
FlutterQuill provides some JSON serialization support so that you can save and open documents. To save a document as JSON, do something like the following:
final 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:
final json = jsonDecode(r'{"insert":"hello\n"}');
_controller.document = Document.fromJson(json);- Quill Delta

As of version 6.0, embed blocks are not provided by default as part of this package.
Instead, this package provides an interface for all the users to provide their own implementations for embed blocks.
Implementations for image, video, and
formula embed blocks are proved in a separate
package flutter_quill_extensions.

Caution
Converting HTML or Markdown to Delta is highly experimental and shouldn't be used for production applications, while the current implementation we have internally is far from perfect, it could improved however it will likely not work as expected, due to differences between HTML and Delta, see this Quill JS Comment #311458570 for more info.
We only use it internally as it is more suitable for our specific use case, copying content from external websites and pasting it into the editor
previously breaks the styles, while the current implementation is not designed for converting a full Document from other formats to Delta, it provides a better user experience and doesn't have many downsides.
The support for converting HTML to Quill Delta is quite experimental and used internally when pasting HTML content from the clipboard to the Quill Document.
Converting Delta from/to HTML is not a standard feature in Quill JS or FlutterQuill.
Important
Converting HTML to Delta usually won't work as expected, we highly recommend storing the Document as Delta JSON in the database instead of other formats (e.g., HTML, Markdown, PDF, Microsoft Word, Google Docs, Apple Pages, XML, CSV, etc...)
Converting between HTML and Delta JSON is generally not recommended due to their structural and functional differences.
Sometimes you might want to convert between HTML and Delta for specific use cases:
- Migration: If you're using an existing system that stores the data in HTML and want to convert the document data to Delta.
- Sharing: For example, if you want to share the Document Delta somewhere or send it as an email.
- Save as: If your app has a feature that allows converting Documents to other formats.
- Rich text pasting: If you copy some content from websites or apps, and want to paste it into the app.
- SEO: In case you want to use HTML for SEO support.
The following packages can be used:
vsc_quill_delta_to_html: To convert Delta to HTML.flutter_quill_delta_from_html: To Convert HTML to Delta.flutter_quill_to_pdf: To convert Delta To PDF.markdown_quill: To convert Markdown To Delta and vice versa.
While spell-checking is not a feature that's implemented into the project, it can be used using external dependencies.
It's implemented using the package simple_spell_checker in the Example.
Take a look at Spelling Checker page for more info.
The package offers translations for the quill toolbar and editor, it will follow the system locale unless you set your own locale.
