how to make gif file with video file in flutter

i'm trying to make gif with video file.

just one - two seconds gif like Tiktok thumnail

but I don't know how to do it

I tryed many things but didn't make it

Image Package

https://pub.dev/packages/image

Variable FPS for animated GIF encoding.

It might be the solution but I can't find any example of it

How Can I make this? anyone?

Solution

UPDATE: Use video_trimmer https://pub.dev/packages/video_trimmer instead

// Example of defining a custom command

// This is already used for creating GIF by
// default, so you do not need to use this.

await _trimmer
    .saveTrimmedVideo(
        startValue: _startValue,
        endValue: _endValue,
        ffmpegCommand:
            '-vf "fps=10,scale=480:-1:flags=lanczos,split[s0][s1];[s0]palettegen[p];[s1][p]paletteuse" -loop 0',
        customVideoFormat: '.gif')
    .then((value) {
  setState(() {
    _value = value;
  });
});

OUTDATED:

flutter_video_compress is an older package, but should work for most situations. Sometimes the file path can be an issue depending on which file picker you choose for videoFile.path

Convert video to a gif

final file = await _flutterVideoCompress.convertVideoToGif(
  videoFile.path,
  startTime: 0, // default(0)
  duration: 2, // default(-1)
  // endTime: -1 // default(-1)
);
debugPrint(file.path);
