Introduction:

FlutterQuill is a rich text editor and a Quill component for Flutter. This library is a WYSIWYG editor built for the modern mobile platform, with web compatibility under development. This dependency is very useful for any editor app. We don’t need any other side for code for any texting editor.

---

Add Dependency:

To add the dependency first you have to open pubspec. ymal file and then add some dependencies,

dependencies:
flutter:
sdk: flutter
cupertino_icons: ^1.0.2
flutter_quill: ^6.1.6

We have to add the updated package of flutter_quill. Which is used as a Rich Text Editor in a flutter.

---

Configuration:

The Quill Toolbar class lets you customize which formatting options are available.

> Font Size:- Within the editor toolbar, a drop-down with font-sizing capabilities is available. This can be enabled or disabled with showFontSize. 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:

fontSizeValues: const {'Small': '7', 'Medium': '20.5', 'Large': '40'},

>Font Family:- If you want to use the font family, you have to add the family to the assets folder and pass in fontfamilyValues.

>Custom Buttons:- You may add custom buttons to the end of the toolbar, via the custom buttons option, which is a List of QuillCustomButton.

QuillCustomButton(
icon:Icons.ac_unit,
onTap: () {
debugPrint('snowflake');
}

>showAlignmentButtons:- In showAlignmentButtons, we have many properties like controller, iconSize, iconTheme, showLeftAlignment, showCenterAlignment, showRightAlignment, showJustifyAlignment, afterButtonPressed.

>Translation:- The package offers translations for the quill toolbar and editor, it will follow the system locale unless you set your own locale with:

QuillToolbar(locale: Locale('fr'), ...)
QuillEditor(locale: Locale('fr'), ...)

Implementation:

In the implementation of Flutter Quill first, we have to create a Flutter project with the name flutter_quill_demo. There are two things in QuillController and Quill-editor. In Quill-controller.

QuillController _controller = QuillController.basic();

here we define the controller as QuillController.basic(). In the Toolbar() we can pass many things like QuillController, toolbarIconAlignment, toolbarIconAlignment, showDividers, showBoldButton, showBoldButton, showUnderLineButton, showJustifyAlignment and many more.

And second is QuillEditor.basic(), in this editor we can type anything.

Scaffold(
body: SingleChildScrollView(
child: Column(
children: [
Container(
margin: EdgeInsets.only(top: 20,left: 10,right: 10,bottom: 20),
width: MediaQuery.of(context).size.width,
height: 80,
decoration: const BoxDecoration(
image: DecorationImage(
image: NetworkImage('https://user-images.githubusercontent.com/10923085/119221946-2de89000-baf2-11eb-8285-68168a78c658.png'),
fit: BoxFit.cover
)
),
),
Padding(padding: const EdgeInsets.only(top: 0),
child:
QuillToolbar.basic(controller: _controller,
fontSizeValues: const {'Small': '7', 'Medium': '20.5', 'Large': '40'},
showAlignmentButtons: false ,
),
),
Padding(
padding: const EdgeInsets.all(8.0),
child: Container(
height: MediaQuery.of(context).size.height,
width: MediaQuery.of(context).size.width,
decoration: const BoxDecoration(
boxShadow: [BoxShadow(
color: Colors.lightBlueAccent,
offset: Offset(5.0, 5.0) ,
blurRadius: 10.0,
spreadRadius: 2.0
),
BoxShadow(
color: Colors.white,
offset: Offset(0.0, 0.0),
blurRadius: 0.0,
spreadRadius: 0.0
)
]
),
child:
QuillEditor.basic(controller: _controller, readOnly: false),),
)
],
),
),
);

When we run the application, we ought to get the screen’s output like the underneath screen capture.

In this picture, as you see we can add colors to our text. And by this, we can create an attractive text list.

In this picture, you can see that we can change the font style for particular text. and also for particular paragraphs.
