使用样例
class RootApp extends StatefulWidget {
  @override
  _RootAppState createState() => _RootAppState();
}

class _RootAppState extends State<RootApp> {
  // 初始化插件
  DisableScreenshots _plugin = DisableScreenshots();
  // 监控截屏行为的stream
  StreamSubscription<void> _screenshotsSubscription;
  int _screenshotsCount = 0;
  bool _disableScreenshots = false;

  @override
  void initState() {
    super.initState();
    _screenshotsSubscription = _plugin.onScreenShots.listen((event) {
      // 监控到截屏行为会回调到这里
      setState(() {
        _screenshotsCount++;
      });
    });
  }

  @override
  Widget build(BuildContext context) {
    return Scaffold(
      appBar: AppBar(
        title: const Text('禁止截屏'),
      ),
      body: Column(
        children: <Widget>[
          Center(
            child: Text("监控到截屏次数:$_screenshotsCount"),
          ),
          Center(
            child: Text(_disableScreenshots ? "禁止截屏状态" : "允许截屏状态"),
          ),
          RaisedButton(
              onPressed: () {
                // 添加默认样式的水印
                _plugin.addWatermark(context, "默认水印",
                    rowCount: 4, columnCount: 8);
              },
              child: Text("添加默认水印")),
          RaisedButton(
              onPressed: () {
                // 添加自定义widget当做水印
                _plugin.addCustomWatermark(context,
                    Watarmark(rowCount: 3, columnCount: 10, text: "自定义水印"));
              },
              child: Text("添加自定义水印")),
          RaisedButton(
              onPressed: () {
                // 移除水印
                _plugin.removeWatermark();
              },
              child: Text("删除水印")),
          RaisedButton(
              onPressed: () async {
                bool flag = !_disableScreenshots;
                // 禁用或允许截屏(只支持iOS)
                await _plugin.disableScreenshots(flag);
                setState(() {
                  _disableScreenshots = flag;
                });
              },
              child: Text(_disableScreenshots ? "允许截屏(仅android适用)" : "禁用截屏(仅android适用)")),
          RaisedButton(
              onPressed: () {
                Navigator.of(context).push(MaterialPageRoute(
                    builder: (_) => Scaffold(
                          appBar: AppBar(
                            title: Text("我是新页面"),
                          ),
                          body: Center(child: Text("new page")),
                        )));
              },
              child: Text("进入新页面"))
        ],
      ),
    );
  }

  @override
  void dispose() {
    super.dispose();
    //取消截屏监控可以调用cancel()方法
    if (_screenshotsSubscription != null) {
      _screenshotsSubscription.cancel();
    }
  }
}
已知问题
  1. 在老的flutter项目中,在iOS平台运行可能出现编译问题无法运行。这个是由于老的flutter项目里面没有使用到swift,所以没有briging文件,但是插件使用了swift,所以会编译失败,这种情况直接使用xcode在iOS项目中创建一个swift文件,会自动生成briding文件。
  2. 在某些安卓设备上(华为P30、Mi 10、三星Note10、OPPO reno3 Pro等),存在不能捕获截屏事件的问题,如果大家有解决方案,请提交pull request,谢谢!

How do I choose a repository?

Start with your use case, compare repository activity, and check the original project before adopting it.

  1. Search by repository name, owner or description, then narrow the results by topic.
  2. Compare stars, forks and recent pushes. Stars show community interest, not a guarantee of quality.
  3. Read the README, license and issues on GitHub before using a project.
