定义:

import 'package:flutter/services.dart';


@immutable
class ClipboardData {
  /// Creates data for the system clipboard.
  const ClipboardData({this.text});

  /// Plain text variant of this clipboard data.
  final String text;
}

class Clipboard {
  Clipboard._();


  static const String kTextPlain = 'text/plain';

  /// Stores the given clipboard data on the clipboard.
  ///将ClipboardData中的内容复制的粘贴板
  static Future<void> setData(ClipboardData data) async {
    await SystemChannels.platform.invokeMethod<void>(
      'Clipboard.setData',
      <String, dynamic>{
        'text': data.text,
      },
    );
  }
}

使用:

ClipboardData data = new ClipboardData(text: text);
Clipboard.setData(data);
