Tencent WeChat Camera Picker

This is a fork package of wechat_camera_picker, and added those following features:

  • Adjust the resolutionPreset automatically, according to the device performance. Aims to solve the issue that video recording may crashed on a mobile phone with relatively lower performance.

  • Fix the issue that it might require for the storage permission twice after captured.

This forked package is maintained by Tencent Cloud Chat.

Thanks a lot to wechat_camera_picker, while their original README can be seen below.

    package="com.your.app">
    <!-- Add this if you need to take photos. -->
    <uses-permission android:name="android.permission.READ_MEDIA_IMAGES" />
    <!-- Add this if you need to take videos. -->

</manifest>

  • CameraPickerViewer.pushToViewer(..., createViewerState: () => CustomCameraPickerViewerState());
