📦 Installation

flutter pub add flutter_quill

OR

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

🛠 Platform Setup

The flutter_quill package uses the following plugins:

1. url_launcher: to open links.
2. quill_native_bridge: to access platform-specific APIs for the editor.
3. 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.

1. Update AndroidManifest.xml

Open your_project/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 your_project/android/app/src/main/res/xml/file_paths.xml with the following content:

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

🚀 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 a document as a JSON:

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

To open the editor with an existing JSON representation that you've previously stored:

final json = jsonDecode(r'{"insert":"hello\n"}');

_controller.document = Document.fromJson(json);

To use your own fonts, update your Assets folder and pass in fontFamilyValues. 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. Implementations for image, video, and formula embed blocks are proved in a separate package flutter_quill_extensions.

🛠️ Using the embed blocks from flutter_quill_extensions

To see how to use the extension package, please take a look at the README of FlutterQuill Extensions

🔄 Conversion to HTML

The following packages can be used:

1. vsc_quill_delta_to_html: To convert Delta to HTML.
2. flutter_quill_delta_from_html: To convert HTML to Delta.
3. flutter_quill_to_pdf: To convert Delta To PDF.
4. markdown_quill: To convert Markdown To Delta and vice versa.

📝 Spelling checker

This feature is currently not implemented and is being planned. Refer to #2246 for discussion.

📝 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.

✂️ Shortcut events

We can customize some Shorcut events, using the parameters characterShortcutEvents or spaceShortcutEvents from QuillEditorConfig to add more functionality to the editor.

To see an example of this, you can check customizing_shortcuts

🌐 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.
