how to scroll in summernote flutter

Updated: As you requested, FlutterSummernote combined with SingleChildScrollView.

It’s working as expected. I don’t know which issue you’ve been facing. Try to write the below-mentioned code into your main.dart file & check the result.

import "package:flutter/material.dart";
import "package:flutter_summernote/flutter_summernote.dart";

void main() {
  WidgetsFlutterBinding.ensureInitialized();
  runApp(const MyApp());
}

class MyApp extends StatelessWidget {
  const MyApp({super.key});

  @override
  Widget build(BuildContext context) {
    return MaterialApp(
      title: "Flutter Demo",
      theme: ThemeData(
        colorScheme: ColorScheme.fromSeed(seedColor: Colors.deepPurple),
        useMaterial3: true,
      ),
      home: const MyHomePage(),
    );
  }
}

class MyHomePage extends StatefulWidget {
  const MyHomePage({super.key});

  @override
  State<MyHomePage> createState() => _MyHomePageState();
}

class _MyHomePageState extends State<MyHomePage> {
  final GlobalKey<FlutterSummernoteState> _keyWhatToDo = GlobalKey();

  @override
  void initState() {
    super.initState();
  }

  @override
  void dispose() {
    _keyWhatToDo.currentState?.dispose();
    super.dispose();
  }

  @override
  Widget build(BuildContext context) {
    return Scaffold(
      body: SafeArea(
        child: SingleChildScrollView(
          child: Column(
            children: <Widget>[
              Container(height: 200, color: Colors.blue),
              Container(height: 200, color: Colors.pink),
              FlutterSummernote(
                widthImage: "40%",
                hasAttachment: true,
                hint: "Your text here...",
                key: _keyWhatToDo,
                height: 450,
                customToolbar: """
              [
                ['style', ['bold', 'italic', 'underline']],
                ['font', ['strikethrough']],
                ['fontsize', ['fontsize']],
                ['color', ['color']],
                ['para', ['ul', 'ol', 'paragraph']],
              ]""",
              ),
              Container(height: 200, color: Colors.orange),
              Container(height: 200, color: Colors.green),
            ],
          ),
        ),
      ),
    );
  }
}
