Flutter Quill provides Flutter developers with a powerful text editor. In this article, we have explained the basic features and usage of Flutter Quill. With Flutter Quill, you can develop an application with the ability to create and edit rich text content. By offering text formatting options to your users, you can provide a more engaging and visually appealing experience. Flutter Quill adds value to your Flutter projects as a robust tool in the text editing domain.

That is simple app:

Step 1: Project Setup After installing the Flutter SDK, create a new Flutter project. You can create a new Flutter project in the terminal using the following command:

flutter create flutter_quill_notes_app

Step 2: Add Dependencies Open the pubspec.yaml file and add the flutter_quill package to the dependencies section. Then, update the package for use in your Flutter project:

dependencies:
  flutter_quill: ^2.0.0

Next, run the following command in the terminal:

flutter pub get

Step 3: Create Screens In the lib folder, create a main.dart file and a folder named screens. Inside the screens folder, create two new files named note_editor_screen.dart and note_viewer_screen.dart.

Step 4: Note Editing Screen Open the note_editor_screen.dart file and add the following code:

import 'package:flutter/material.dart';
import 'package:flutter_quill/flutter_quill.dart';

class NoteEditorScreen extends StatefulWidget {
  @override
  _NoteEditorScreenState createState() => _NoteEditorScreenState();
}

class _NoteEditorScreenState extends State<NoteEditorScreen> {
  QuillController _controller = QuillController.basic();

  @override
  Widget build(BuildContext context) {
    return Scaffold(
      appBar: AppBar(
        title: Text('Note Editor'),
      ),
      body: QuillEditor(
        controller: _controller,
        autoFocus: true,
        readOnly: false,
        expands: true,
      ),
    );
  }
}

Step 5: Note Viewing Screen Open the note_viewer_screen.dart file and add the following code:

import 'package:flutter/material.dart';
import 'package:flutter_quill/flutter_quill.dart';

class NoteViewerScreen extends StatelessWidget {
  final String noteContent;

  const NoteViewerScreen({Key? key, required this.noteContent}) : super(key: key);

  @override
  Widget build(BuildContext context) {
    return Scaffold(
      appBar: AppBar(
        title: Text('Note Viewer'),
      ),
      body: Padding(
        padding: EdgeInsets.all(16.0),
        child: QuillViewer(
          document: Document.fromJson(noteContent),
          scrollable: true,
          showToolbar: false,
        ),
      ),
    );
  }
}

Step 6: Main App Flow Update the main.dart file with the following code:

import 'package:flutter/material.dart';
import 'package:flutter_quill_notes_app/screens/note_editor_screen.dart';
import 'package:flutter_quill_notes_app/screens/note_viewer_screen.dart';

void main() {
  runApp(FlutterQuillNotesApp());
}

class FlutterQuillNotesApp extends StatelessWidget {
  @override
  Widget build(BuildContext context) {
    return MaterialApp(
      title: 'Flutter Quill Notes',
      theme: ThemeData(
        primarySwatch: Colors.blue,
      ),
      initialRoute: '/',
      routes: {
        '/': (context) => NoteEditorScreen(),
        '/viewer': (context) => NoteViewerScreen(noteContent: ''),
      },
    );
  }
}

Step 7: Launch the App Run your project and launch the application on a device or emulator. You will see a text editor screen where you can create and edit your notes. You can then click on the “Viewer” button on the main screen to view the notes.

By following these steps, you can create a simple note-taking application using Flutter and Flutter Quill. The application allows users to create, edit, and view their notes.
