Flutter屏幕录制插件ldev_screen_recording的使用

flutter_screen_recording

这是一个用于在Flutter应用中录制屏幕的新插件。该插件要求Android SDK版本为21及以上，iOS系统版本为10及以上。

开始使用

1. 开始录制

bool started = FlutterScreenRecording.startRecordScreen(videoName);

或者

bool started = FlutterScreenRecording.startRecordScreenAndAudio(videoName);

上述代码中的videoName是用户定义的视频文件名。

2. 停止录制

String path = FlutterScreenRecording.stopRecordScreen;

path变量将包含录制完成后的视频文件路径。

Android配置

此插件本身不需要请求权限，但为了确保功能正常运行，建议使用permission_handler插件来管理权限。你需要在AndroidManifest.xml中添加以下权限：

<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" />
<uses-permission android:name="android.permission.WRITE_INTERNAL_STORAGE" />
<uses-permission android:name="android.permission.RECORD_AUDIO" />

此外，在AndroidManifest.xml的<application>标签内添加以下服务配置：

<service
    android:name="com.foregroundservice.ForegroundService"
    android:foregroundServiceType="mediaProjection">
</service>

iOS配置

在Info.plist文件中添加以下权限描述信息：

<key>NSPhotoLibraryUsageDescription</key>
<string>Save video in gallery</string>
<key>NSMicrophoneUsageDescription</key>
<string>Save audio in video</string>

Web支持

从版本2.0.0开始，该插件支持Web平台。
