Flutter：Get the first frame of the video

Question

How to get the first frame of the local video file in the Flutter project? Here is my code:

ImagePicker.pickVideo(source: ImageSource.camera).then((File file) {
  if (file != null && mounted) {
    //I got the video file here, but I want to get the first frame of the video.
  }
 });
},

Answer 1

String thumb = await Thumbnails.getThumbnail(
    thumbnailFolder:'[FOLDER PATH TO STORE THUMBNAILS]', // creates the specified path if it doesnt exist
    videoFile: '[VIDEO PATH HERE]',
    imageType: ThumbFormat.PNG,
    quality: 30);

/*
* thumbnailFolder property can be omitted if you dont wish to keep the generated thumbails past each usage
*/
