This library is a WYSIWYG 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.
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:
It is required to provide `EmbedBuilder`, e.g. [defaultEmbedBuildersWeb](https://github.com/singerdmx/flutter-quill/blob/master/example/lib/universal_ui/universal_ui.dart#L99).
Also it is required to provide `webImagePickImpl`, e.g. [Sample Page](https://github.com/singerdmx/flutter-quill/blob/master/example/lib/pages/home_page.dart#L317).
It is required to provide `filePickImpl` for toolbar image button, e.g. [Sample Page](https://github.com/singerdmx/flutter-quill/blob/master/example/lib/pages/home_page.dart#L297).
This project use some adaptive widgets like `AdaptiveTextSelectionToolbar` which require the following delegates:
1. Default Material Localizations delegate
2. Default Cupertino Localizations delegate
3. Defualt Widgets Localizations delegate
You don't need to include those since there are defined by default
but if you are using Custom app or you are overriding the `localizationsDelegates` in the App widget
then please make sure it's including those:
```dart
localizationsDelegates: const [
DefaultCupertinoLocalizations.delegate,
DefaultMaterialLocalizations.delegate,
DefaultWidgetsLocalizations.delegate,
],
```
And you might need more depending on your use case, for example if you are using custom localizations for your app, using custom app widget like [FluentApp](https://pub.dev/packages/fluent_ui)
which will also need
```dart
localizationsDelegates: const [
// Required localizations delegates ...
FluentLocalizations.delegate,
AppLocalizations.delegate,
],
```
in addition to the required delegates by this library
When enabled, the default font-size values can be modified via _optional_`fontSizeValues`. `fontSizeValues` accepts a `Map<String, String>` consisting of a `String` title for the font size and a `String` value for the font size. Example:
To use your own fonts, update your [assets folder](https://github.com/singerdmx/flutter-quill/tree/master/example/assets/fonts) and pass in `fontFamilyValues`. More details at [this change](https://github.com/singerdmx/flutter-quill/commit/71d06f6b7be1b7b6dba2ea48e09fed0d7ff8bbaa), [this article](https://stackoverflow.com/questions/55075834/fontfamily-property-not-working-properly-in-flutter) and [this](https://www.flutterbeads.com/change-font-family-flutter/).
As of version 6.0, embed blocks are not provided by default as part of this package. Instead, this package provides an interface to all the user to provide there own implementations for embed blocks. Implementations for image, video and formula embed blocks is proved in a separate package [`flutter_quill_extensions`](https://pub.dev/packages/flutter_quill_extensions).
Sometimes you want to add some custom content inside your text, custom widgets inside of them. An example is adding notes to the text, or anything custom that you want to add in your text editor.
The only thing that you need is to add a `CustomBlockEmbed` and provider a builder for it to the `embedBuilders` parameter, to transform the data inside of the Custom Block into a widget!
Starting with the `CustomBlockEmbed`, here we extend it and add the methods that are useful for the 'Note' widget, that will be the `Document`, used by the `flutter_quill` to render the rich text.
Document get document => Document.fromJson(jsonDecode(data));
}
```
After that, we need to map this "notes" type into a widget. In that case, I used a `ListTile` with a text to show the plain text resume of the note, and the `onTap` function to edit the note.
Don't forget to add this method to the `QuillEditor` after that!
And finally, we write the function to add/edit this note. The `showDialog` function shows the QuillEditor to edit the note, after the user ends the edition, we check if the document has something, and if it has, we add or edit the `NotesBlockEmbed` inside of a `BlockEmbed.custom` (this is a little detail that will not work if you don't pass the `CustomBlockEmbed` inside of a `BlockEmbed.custom`).
The translation file is located at [toolbar.i18n.dart](lib/src/translations/toolbar.i18n.dart). Feel free to contribute your own translations, just copy the English translations map and replace the values with your translations. Then open a pull request so everyone can benefit from your translations!
To aid in testing applications using the editor an extension to the flutter `WidgetTester` is provided which includes methods to simplify interacting with the editor in test cases.
