🛠 Platform Specific Configurations

Before using the package, we must inform you the package uses the following plugins:

1. url_launcher to open links.
2. device_info_plus to view info about the current device.
3. flutter_keyboard_visibility to listen for keyboard visibility changes.

All of them don't require any platform-specific setup.

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, take a look at flutter_quill_extensions Readme.

🚀 Usage

First, you need to instantiate a controller

QuillController _controller = QuillController.basic();

And then use the QuillEditor, QuillToolbar widgets, connect the QuillController to them

QuillToolbar.simple(
  configurations: QuillSimpleToolbarConfigurations(
    controller: _controller,
    sharedConfigurations: const QuillSharedConfigurations(
      locale: Locale('de'),
    ),
  ),
),
Expanded(
  child: QuillEditor.basic(
    configurations: QuillEditorConfigurations(
      controller: _controller,
      readOnly: false,
      sharedConfigurations: const QuillSharedConfigurations(
        locale: Locale('de'),
      ),
    ),
  ),
)

Depending on your use case, you might want to dispose of the _controller in dispose method

in most cases, it's better to.

🔄 Migration

Starting from version 8.0.0 We have added Migration Guide for migration from different versions

🔤 Input / Output

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);

🖋 Font Family

To use your own fonts, update your Assets folder and pass in fontFamilyValues. More details on this commit, this article and this.

📦 Embed Blocks

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.

🔄 Conversion to HTML

Having your document stored in Quill Delta format is sometimes not enough. Often you'll need to convert it to other formats such as HTML to publish it, or send an email.

Note: This package supports converting from HTML back to Quill delta but it's experimental and used internally when pasting HTML content from the clipboard to the Quill Editor

You have two options:

1. Using quill_html_converter to convert to HTML, the package can convert the Quill delta to HTML well (it uses vsc_quill_delta_to_html), it is just a handy extension to do it more quickly
2. Another option is to use vsc_quill_delta_to_html to convert your document to HTML. This package has full support for all Quill operations—including images, videos, formulas, tables, and mentions. Conversion can be performed in vanilla Dart (i.e., server-side or CLI) or in Flutter. It is a complete Dart part of the popular and mature quill-delta-to-html Typescript/Javascript package. this package doesn't convert the HTML back to Quill Delta as far as we know

Converting to Delta from Markdown and HTML is highly experimental and shouldn't be used for production applications, while the current implementation is far from perfect, it could improved a lot however it will likely not work as expected, due to differences between HTML and Delta, see this comment for more info.
We 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 ready, it provides a better user experience and doesn't have many downsides.

🌐 Translation

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