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.

Android 13 (API 33) permissions

If you don't need to take photos or videos, consider removing relevant permission in your apps, more specifically:

<manifest xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:tools="http://schemas.android.com/tools"
    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. -->
    <uses-permission android:name="android.permission.READ_MEDIA_VIDEO" />
</manifest>

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