                  // FocusManager.instance.primaryFocus?.unfocus();

                  // Focus.of(context).unfocus();

                  // FocusScope.of(context).unfocus();

                  // FocusScope.of(context).requestFocus(FocusNode());

                  // FocusScopeNode currentFocus = FocusScope.of(context);
                  // if (!currentFocus.hasPrimaryFocus) {
                  //   currentFocus.focusedChild?.unfocus();
                  // }
                },

}

class MySelectionControls extends MaterialTextSelectionControls {
  final Function onPaste;

  MySelectionControls({required this.onPaste});

  @override
  Future<void> handlePaste(TextSelectionDelegate delegate) {
    onPaste();
    return super.handlePaste(delegate);
  }
}

Try this one

import 'package:flutter/material.dart';

void main() {
  runApp(const MyApp());
}

class MyApp extends StatelessWidget {
  const MyApp({Key? key}) : super(key: key);

  // This widget is the root of your application.
  @override
  Widget build(BuildContext context) {
    return const MaterialApp(
      home: Home(),
    );
  }
}

class Home extends StatefulWidget {
  const Home({key});

  @override
  State<Home> createState() => _HomeState();
}

class _HomeState extends State<Home> {
  TextSelectionControls? _textSelectionControls;
  @override
  void initState() {
    // TODO: implement initState
    super.initState();
    _textSelectionControls = MySelectionControls(onPaste: onPaste);
  }

  @override
  Widget build(BuildContext context) {
    return Scaffold(
      body: SafeArea(
        child: Padding(
          padding: const EdgeInsets.all(8),
          child: Center(
            child: Column(
              children: [
                TextField(
                  selectionControls: _textSelectionControls,
                ),
              ],
            ),
          ),
        ),
      ),
    );
  }

  Future<void> onPaste(final TextSelectionDelegate? delegate) async {
    Future.delayed(Duration(milliseconds: 100), () {
      FocusScope.of(context).requestFocus(FocusNode());
    });
  }
}

class MySelectionControls extends MaterialTextSelectionControls {
  MySelectionControls({required this.onPaste});
  ValueChanged<TextSelectionDelegate> onPaste;
  @override
  Future<void> handlePaste(TextSelectionDelegate delegate) async {
    onPaste(delegate);
    return super.handlePaste(delegate);
  }
}

I have tested this and its working
