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.

Tip
Using the latest version and reporting any issues you encounter on GitHub will greatly contribute to the improvement of the library. Your input and insights are valuable in shaping a stable and reliable version for all the developers. Thank you for being part of the open-source community!
The flutter_quill
package uses the following plugins:
url_launcher
to open links.device_info_plus
to view info about the current device.flutter_keyboard_visibility
to 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.
Donβt be confused by its name DeltaβDeltas 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);

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
.
Provide a list of embed

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.
A spell checker is a software tool or feature integrated into various text processing applications that automatically identifies and corrects spelling errors in a written document. It works by comparing the words in the text against a built-in dictionary. If a word isn't found in the dictionary or doesn't match any known word patterns, the spell checker highlights it as a potential error.
- Improved Accuracy: It helps writers avoid common spelling mistakes, ensuring that the text is free of errors.
- Time-Saving: Automatically detecting errors reduces the time needed for manual proofreading.
- Enhanced Professionalism: Correctly spelled words contribute to the overall professionalism of documents, which is crucial in academic, business, and formal writing.
- Multilingual Support: Many spell checkers support multiple languages, making it easier for users to write accurately in different languages.
Important
The spell checker usually does not work as expected in most cases. Many translations are not supported such as: Chinese
, Japanese
, Korean
, Hebrew
, Arabic
, Russian
, etc. For now it is a purely experimental feature that may have code that will be modified in future versions.
- German -
de
(may contain errors or missing words) - English -
en
(currently adding missing translations) - Spanish -
es
(currently adding missing translations) - French -
fr
(may contain errors or missing words) - Italian -
it
(currently adding missing translations) - Norwegian -
no
(may contain errors or missing words) - Portuguese -
pt
(may contain errors or missing words) - Swedish -
sv
(may contain errors or missing words)
Note: If you have knowledge about any of these available languages or the unsupported ones, you can make a pull request to add support or add words that are not currently in simple_spell_checker.
In order to activate this functionality you can use the following code:
// you can use the language of your preference or directly select the language of the operating system
final language = 'en'; // or Localizations.localeOf(context).languageCode
FlutterQuillExtensions.useSpellCheckerService(language);
When you no longer need to have the Spell checker activated you can simply use dispose()
of the SpellCheckerServiceProvider
class:
// dispose all service and it cannot be used after this
SpellCheckerServiceProvider.dispose();
If what we want is to close the StreamControllers without deleting the values that are already stored in it, we can set onlyPartial
to true
.
// it can be still used by the editor
SpellCheckerServiceProvider.dispose(onlyPartial: true);
One use of this would be having the opportunity to activate and deactivate the service when we want, we can see this in the example that we have in this package, in which you can see that on each screen, we have a button that dynamically activates and deactivates the service. To do this is pretty simple:
SpellCheckerServiceProvider.toggleState();
// use isServiceActive to get the state of the service
SpellCheckerServiceProvider.isServiceActive();
setState(() {});

The package offers translations for the quill toolbar and editor, it will follow the system locale unless you set your own locale.
