如何解开Texfield并将Keybaord隐藏在糊状扑来中

Question

我有一个我的文本字段，主要是粘贴内容，所以我想解开textfield并在糊状上隐藏键盘，因此我有能力使用Textfield SelectionControls处理粘贴，但问题是Focusing和Keybaord，而Keybaord正在重新开放我疲倦的所有焦点方法来解散关注的方法这是我的代码

import 'package:flutter/material.dart';

main() => runApp(const App());

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

  @override
  Widget build(BuildContext context) {
    return const MaterialApp(home: Home());
  }
}

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

  @override
  Widget build(BuildContext context) {
    return Scaffold(
      body: SafeArea(
        child: Padding(
          padding: const EdgeInsets.all(8),
          child: Center(
            child: TextField(
              selectionControls: MySelectionControls(
                onPaste: () {
                  print('onPaste');

                  // 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);
  }
}

尝试这个

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);
  }
}

我已经测试过的及其工作
