如何在 Flutter 中监控剪贴板？

Question

我正在寻找一种在 Flutter 中监视剪贴板的方法，我能找到的与 Flutter 上剪贴板交互相关的所有内容是：Clipboard class，

有谁知道如何在 Flutter 中监控系统剪贴板中的新项目，最好使用插件？

Answer 1

可能有点晚了，但仍然如此。不需要插件或库，解决方案可能非常简单。以下是如何监控剪贴板内容的基本示例：

#creating a listening Stream:
final clipboardContentStream = StreamController<String>.broadcast();

#creating a timer for updates:
Timer clipboardTriggerTime;

clipboardTriggerTime = Timer.periodic(
# you can specify any duration you want, roughly every 20 read from the system
      const Duration(seconds: 5),
      (timer) {
        Clipboard.getData('text/plain').then((clipboarContent) {
          print('Clipboard content ${clipboarContent.text}');

          # post to a Stream you're subscribed to
          clipboardContentStream.add(clipboarContent.text);
        });
      },
    );

# subscribe your view with
Stream get clipboardText => clipboardController.stream

# and don't forget to clean up on your widget
@override
void dispose() {
  clipboardContentStream.close();

  clipboardTriggerTime.cancel();
}
