📦 Installation

flutter pub add flutter_quill

OR

dependencies:
  flutter_quill:
    git:
      url: https://github.com/singerdmx/flutter-quill.git
      ref: v<latest-version-here>

Tip

If you're using version 10.0.0, see the migration guide to migrate to 11.0.0.

🛠 Platform Setup

The flutter_quill package uses the following plugins:

url_launcher: to open links.
quill_native_bridge: to access platform-specific APIs for the editor.
flutter_keyboard_visibility_temp_fork to listen for keyboard visibility changes.

Android Configuration for `quill_native_bridge`

To support copying images to the clipboard to be accessed by other apps, you need to configure your Android project. If not set up, a warning will appear in the log during debug mode only.

Tip

This is only required on Android for this optional feature. You should be able to copy images and paste them inside the editor without any additional configuration.

1. Update AndroidManifest.xml

Open android/app/src/main/AndroidManifest.xml and add the following inside the <application> tag:

<manifest>
    <application>
        ...
        <provider
            android:name="androidx.core.content.FileProvider"
            android:authorities="${applicationId}.fileprovider"
            android:exported="false"
            android:grantUriPermissions="true" >
            <meta-data
                android:name="android.support.FILE_PROVIDER_PATHS"
                android:resource="@xml/file_paths" />
        </provider>
        ...
    </application>
</manifest>

2. Create file_paths.xml

Create the file android/app/src/main/res/xml/file_paths.xml with the following content:

<paths>
    <cache-path name="cache" path="." />
</paths>

Note

Starting with Flutter Quill 10.8.4, super_clipboard is no longer required in flutter_quill or flutter_quill_extensions. The new default is an internal plugin quill_native_bridge. If you want to continue using super_clipboard, you can use the quill_super_clipboard package (support may be discontinued).

🚀 Usage

Add the localization delegate to your app widget:

import 'package:flutter_quill/flutter_quill.dart';
import 'package:flutter_localizations/flutter_localizations.dart';

MaterialApp(
  localizationsDelegates: const [
    GlobalMaterialLocalizations.delegate,
    GlobalCupertinoLocalizations.delegate,
    GlobalWidgetsLocalizations.delegate,
    FlutterQuillLocalizations.delegate,
  ]，
);

Instantiate a controller:

QuillController _controller = QuillController.basic();

Use the QuillEditor and QuillSimpleToolbar widgets, and attach the QuillController to them:

QuillSimpleToolbar(
  controller: _controller,
  config: const QuillSimpleToolbarConfig(),
),
Expanded(
  child: QuillEditor.basic(
    controller: _controller,
    config: const QuillEditorConfig(),
  ),
)

Dispose of the QuillController in the dispose method:

@override
void dispose() {
  _controller.dispose();
  super.dispose();
}

Check out Sample Page for more advanced usage.

💥 Breaking Changes

APIs marked with @experimental are subject to change or removal at any time and should be used with caution, as they may be altered even in minor versions.
APIs marked with @internal and @visibleForTesting are not intended for public use and should be avoided entirely.
The package:flutter_quill/internal.dart expose internal APIs to be used by other related packages and should be avoided when possible.

We make every effort to ensure internal APIs are not exported by default. Use experimental features at your own discretion.

We recommend checking the CHANGELOG.md or release notes for each update to stay informed.

🔤 Input / Output

This library utilizes Quill Delta to represent document content. The Delta format is a compact and versatile method for describing document changes through a series of operations that denote insertions, deletions, or formatting changes.

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

To save the document:

final String json = jsonEncode(_controller.document.toDelta().toJson());
// Stores the JSON Quill Delta

To load the document:

final String json = ...; // Load the previously stored JSON Quill Delta

_controller.document = Document.fromJson(jsonDecode(json));

To change the read-only mode:

_controller.readOnly = true; // Or false to allow edit

⚙️ Configurations

The QuillSimpleToolbar and QuillEditor widgets are both customizable. Sample Page provides sample code for advanced usage and configuration.

🖋 Font Family

To use your own fonts, update your Assets directory and pass in items to QuillToolbarFontFamilyButton's options. More details on this commit, this article and this.

📦 Embed Blocks

The flutter_quill package provides an interface for all the users to provide their own implementations for embed blocks.

Refer to the Custom Embed Blocks for more details.

🛠️ Using the embed blocks from `flutter_quill_extensions`

The flutter_quill_extensions package provide implementations for image and video embed blocks.

🔄 Delta Conversion

Caution

Storing the Delta as HTML in the database to convert it back to Delta when loading the document is not recommended due to the structural and functional differences between HTML and Delta (see this comment). We recommend storing the Document as Delta JSON instead of other formats (e.g., HTML, Markdown, PDF, Microsoft Word, Google Docs, Apple Pages, XML).

Converting Delta from/to HTML is not a standard feature in Quill JS or Flutter Quill.

Available Packages for Conversion

Package	Description
`vsc_quill_delta_to_html`	Converts Delta to HTML.
`flutter_quill_delta_from_html`	Converts HTML to Delta.
`flutter_quill_to_pdf`	Converts Delta to PDF.
`markdown_quill`	Converts Markdown to Delta and vice versa.
`flutter_quill_delta_easy_parser`	Converts Quill Delta into a simplified document format, making it easier to manage and manipulate text attributes.

Tip

You might want to convert between HTML and Delta for some 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.

📝 Rich Text Paste

This feature allows the user to paste the content copied from other apps into the editor as rich text. The plugin quill_native_bridge provides access to the system Clipboard.

Important

Currently this feature is unsupported on the web. See issue #1998 and issue #2220 for more details.

🌐 Translation

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

See the translation page for more info.

🧪 Testing

Take a look at flutter_quill_test for testing.

Currently, the support for testing is limited.
