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.
  }
 });
},
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
*/

Flutter (software), Flutter is an open-source UI software development kit created by Google. It is used to develop applications for Android, iOS, Windows, Mac, Linux, Google  Flutter is Google’s UI toolkit for building beautiful, natively compiled applications for mobile, web, and desktop from a single codebase.

The below code uses the video_thumbnail plugin which shows support for both Android and ios in its documentation

Future genThumbnailFile() async{
    final thumbnail = await VideoThumbnail.thumbnailFile(
        video:
        _video.path,
        // thumbnailPath: _tempDir,
        imageFormat: ImageFormat.JPEG,
        //maxHeightOrWidth: 0,
        maxHeight:3,
        maxWidth: 2,
        quality: 10);
    setState(() {
      final file = File(thumbnail);
      filePath = file.path;
    });
  }

Then use this filePath variable in the Image widget as follows

filePath != null
                      ? Container(
                      width:400,
                      height: 200,
                      child: Image(image: AssetImage(filePath)))
                      : Text('No Floatting Button Click')

Use export_video_frame, it works for IOS.

var duration = Duration(seconds: 1);
var image = await ExportVideoFrame.exportImageBySeconds(widget.file, duration, 0);

I implemented this using thumbnails of pub.

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);

Introduction to Flutter Development with Dart, Our Flutter development course teaches you how to code using Dart and build beautiful, fast, native-quality iOS and Android apps. Even if you have ZERO  Flutter engine. Flutter's engine, written primarily in C++, provides low-level rendering support using Google's Skia graphics library. Additionally, it interfaces with platform-specific SDKs such as those provided by Android and iOS. The Flutter Engine is a portable runtime for hosting Flutter applications.

Comments
  • Can you post the code of what you have tried?
  • 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. } }); },
  • Kindly add that in your question, it is difficult to analyze code in comment.
  • The code is below,please see it
  • Try this pub.dartlang.org/packages/video_player, and the logic would be to take the thumbnail of the video at 0th second. Personally I have never used this plugin before, so I am not sure what other functions it offer.
  • Could you please add some explanation for your code and how this answers the question?
  • This answer works only with Android. Flutter main selling point is being cross-platform, if you post a solution please explicitly state it works only halfway.
  • Kindly delete this from answer. I updated your question.
