[!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!
π Platform Specific Configurations
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 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>
[!NOTE] Starting with Flutter Quill
10.8.4
, super_clipboard is no longer required influtter_quill
orflutter_quill_extensions
. The new default is an internal plugin,quill_native_bridge
. If you want to continue usingsuper_clipboard
, you can use the quill_super_clipboard package (support may be discontinued).
π Usage
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.
π₯ 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/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.
π€ 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.
[!NOTE] 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.
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);

π¦ 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
.
π οΈ 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

π Conversion to HTML
[!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.<br> 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.
π Spelling checker
This feature is currently not implemented and is being planned. Refer to #2246 for discussion.
π 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 not supported on the web. See issue #1998 and issue #2220 for more details
βοΈ Shortcut events
We can customize some Shorcut events, using the parameters characterShortcutEvents
or spaceShortcutEvents
from QuillEditorConfigurations
to add more functionality to our editor.
[!NOTE]
You can get all standard shortcuts using
standardCharactersShortcutEvents
orstandardSpaceShorcutEvents
To see an example of this, you can check customizing_shortcuts
π Translation
The package offers translations for the quill toolbar and editor, it will follow the system locale unless you set your own locale.

π§ͺ Testing
Take a look at flutter_quill_test for testing.
Notice that currently, the support for testing is limited.
π€ Contributing
[!IMPORTANT] At this time, we prioritize bug fixes and code quality improvements over new features. Please refrain from submitting large changes to add new features, as they might not be merged, and exceptions may made. We encourage you to create an issue or reach out beforehand, explaining your proposed changes and their rationale for a higher chance of acceptance. Thank you!
We greatly appreciate your time and effort.
