desktop_clipboard 是一个用于在 Flutter 桌面应用程序中操作剪贴板的插件。它支持 Windows、macOS 和 Linux 平台。使用这个插件，你可以轻松地将文本复制到剪贴板或从剪贴板中读取文本。

安装

首先，你需要在 pubspec.yaml 文件中添加 desktop_clipboard 依赖：

dependencies:
  flutter:
    sdk: flutter
  desktop_clipboard: ^0.0.5

然后运行 flutter pub get 来安装依赖。

使用

1. 复制文本到剪贴板

你可以使用 DesktopClipboard.setData 方法将文本复制到剪贴板。

import 'package:desktop_clipboard/desktop_clipboard.dart';

void copyToClipboard() async {
  try {
    await DesktopClipboard.setData(ClipboardData(text: 'Hello, World!'));
    print('Text copied to clipboard');
  } catch (e) {
    print('Failed to copy text: $e');
  }
}

2. 从剪贴板中读取文本

你可以使用 DesktopClipboard.getData 方法从剪贴板中读取文本。

import 'package:desktop_clipboard/desktop_clipboard.dart';

void readFromClipboard() async {
  try {
    ClipboardData? data = await DesktopClipboard.getData();
    if (data != null && data.text != null) {
      print('Text from clipboard: ${data.text}');
    } else {
      print('Clipboard is empty or does not contain text');
    }
  } catch (e) {
    print('Failed to read text: $e');
  }
}

示例

以下是一个完整的示例，展示了如何将文本复制到剪贴板并从剪贴板中读取文本：

import 'package:flutter/material.dart';
