WITH SOLUTION: MissingPluginException (MissingPluginException(No implementation found for method data on channel video_thumbnail))

MissingPluginException (MissingPluginException(No implementation found for method data on channel video_thumbnail))

Same issue here but not resolved: https://github.com/justsoft/video_thumbnail/issues/26

I'm getting same error. I found the bug and how to fix it. If there is space characters in file names, it gives this error. I tested for the same file. One for the file name with space characters and without space characters and I don't get any error about it for the file name without spaces.

Solution: your file names should not have spaces (or maybe other non-ASCII chars) not to get this error.

I handle this situation using following code:

// the file name pattern we want
RegExp regExp = new RegExp(
    r"/^[a-zA-Z0-9_-]+$/",
    caseSensitive: false,
    multiLine: false,
);

if (!regExp.hasMatch(mediaFile.path)) {
    String tempDir = (await getTemporaryDirectory()).path;
    String fileExtension = mediaFile.path.split('.').last;
    String newPath =
        tempDir + '/' + DateTime.now().millisecondsSinceEpoch.toString() + '.' + fileExtension;

    File tempFile =
        await mediaFile.copy(newPath);

    // you can use this new file path for making the thumbnail without error
    mediaPath = tempFile.path;
}

Thanks for your suggestion. Please take a look my recent updated README regarding the input URL.

To generate the thumbnail from a network resource, the video must be properly URL encoded.

Please try the URL encoded 'video' and leave the output thumbnail path as default to see still an issue.

It's not about remote resource, about local file.

I shared code snippet about handling the error. Please check out it at the bottom of question post.

Have you tried:

• ) The local file can be readable by this App?
• ) Can generate the thumbnail in memory by calling thumbnailData?
• ) the destination folder has the permissions for writing a file?
