Unhandled Exception: MissingPluginException(No implementation found for method file on channel video_thumbnail)

[nanian]

final uint8list = await VideoThumbnail.thumbnailFile(
video: photoBean.path,
imageFormat: ImageFormat.JPEG,
// specify the width of the thumbnail, let the height auto-scaled to keep the source aspect ratio
quality: 55,
);
我用的video_thumbnail: ^0.3.1最新版，现在还是有这个问题老哥，能在修复下吗

Please check the video is playable on your device.

视频是手机拍摄的，可以正常播放，拿到视频地址后获取不到第一帧

老哥：我的flutter还没升级2.0呢，没办法用0.3.1的版本，如果用之前的版本会不会有问题呢，能否兼容下2.0以下的版本，在线等

Please take a look my example.

I also encountered this problem. Finally, I found that it was due to the problem of quality setting. If I set the quality to 200, It would fail. If I set the quality to 100, It would success.
await VideoThumbnail.thumbnailFile(
video: _videoPath,
thumbnailPath: (await getTemporaryDirectory()).path,
imageFormat: ImageFormat.JPEG,
maxHeight: 1000,
quality: 100,
)

Thanks for the finding, the quality should be 100 or less, it is the percentage of quality of the original image.
