This library is a WYSIWYG editor built for the modern mobile platform, with web compatibility under development. 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.
* Use `_controller.document.toDelta()` to extract the deltas.
* Use `_controller.document.toPlainText()` to extract plain text.
FlutterQuill provides some JSON serialisation support, so that you can save and open documents. To save a document as JSON, do something like the following:
```
var 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:
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:
It is required to provide `EmbedBuilder`, e.g. [defaultEmbedBuilderWeb](https://github.com/singerdmx/flutter-quill/blob/master/example/lib/universal_ui/universal_ui.dart#L28).
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#L225).
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#L205).
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 map it into the `customElementsEmbedBuilder`, to transform the data inside of the Custom Block into a widget!
Here is an example:
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`).
