Question

当前，我要在用户设备上创建“复制到剪贴板”事件。

当用户单击“列表视图前导icon.content复制”时，则文本应存储在其设备剪贴板上。

请有人可以帮助我吗？

Widget _buildListItem(BuildContext context, DocumentSnapshot data) {
    final record = Record.fromSnapshot(data);

    return Padding(
      key: ValueKey(record.name),
      padding: const EdgeInsets.symmetric(horizontal: 16.0, vertical: 8.0),
      child: Container(
        decoration: BoxDecoration(
          border: Border.all(color: Colors.grey),
          borderRadius: BorderRadius.circular(5.0),
        ),
        child: ListTile(
          leading: Icon(Icons.content_copy),
          title: Text(record.group),
          subtitle: Text(record.name),
          // can anyone help me how to create event on onTap action.
          // When user click then text copy to clipboard on his device. 
             onTap: () {
             debugPrint ("Tapped");
          },
          ),
      ),
    );
  }
}

class Record {
  final String name;
  final String group;
  final DocumentReference reference;

  Record.fromMap(Map<String, dynamic> map, {this.reference})
      : assert(map['name'] != null),
        assert(map['group'] != null),
        name = map['name'],
        group = map['group'];

  Record.fromSnapshot(DocumentSnapshot snapshot)
      : this.fromMap(snapshot.data, reference: snapshot.reference);

  @override
  String toString() => "Record<$name:$group>";
}

Answer 1

import 'package:flutter/services.dart';

在您的onTap内添加以下内容：

onTap:(){
   Clipboard.setData(new ClipboardData(text: record.name));
   Scaffold.of(context).showSnackBar(SnackBar
     (content: Text('text copied')));
}

如果由于小吃店Sami Kanafani的回答引发异常，请尝试适用于我的解决方案。

final GlobalKey<ScaffoldState> _scaffoldKey = GlobalKey<ScaffoldState>();

...//build method
Scaffold(
key: _scaffoldKey,
appBar: _appBar,
body: _content,
floatingActionButton: FloatingActionButton.extended(
label: Text('copy'),
onPressed:(){
  Clipboard.setData(new ClipboardData(text: record.name));
   _scaffoldKey.currentState.showSnackBar(SnackBar
     (content: Text('text copied')));
}
)
