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

[atheist1]

I changed the plugin photo which i pick video before to the plugin file_picker and then i get this error.
The difference between this two plugin may be is the path to the file.First plugin copy the file to application temp storage then give a new path and the second one give an absolute path(/storage/emulated/0/DCIM/Camera/VID_20200420_171228.mp4).
what should i do if i dont wont to copy the original file?
The plugins version is 0.2.0. and the code is

static getVideoThumbNail(String filePath) async {
    String tempPath = (await getLocalOrTempDir()).path;
    try {
      var imageData = await VideoThumbnail.thumbnailFile(
        video: filePath,
        imageFormat: ImageFormat.PNG,
        maxWidth: 256,
        maxHeight: 256,
        thumbnailPath: tempPath,
        quality: 50,
      );
      return imageData;
    } catch (e) {
      print(e);
      eventBus.fire(showToast(CommonUtils.getLocale(null).noThumbnail));
      return null;
    }
  }

You need to make sure your App has permission to read the absolute path.
You might use File class to check the App can read from the video first.
Take a look my example or my comments for other users, or just google it.
Basically it needs read permissions for the photo gallery.

[atheist1]

I have give the permission to my app.
I write those on my AndroidManifest.xml

 <uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE"/>
    <uses-permission android:name="android.permission.READ_EXTERNAL_STORAGE"/>
    <uses-permission android:name="android.permission.CAMERA" />
    <uses-permission android:name="android.permission.RECORD_AUDIO" />

and the video is record by my phone. I am sure that the video can play on my phone.
I rewrite the code to this.

  static getVideoThumbNail(String filePath) async {
    String tempPath = (await getLocalOrTempDir()).path;
    try {
      File file = new File(filePath);
      print('exists ${file.existsSync()}');

      print('tempPath ${tempPath}');
//      var imageData = await VideoThumbnail.thumbnailFile(
//        video: filePath,
//        imageFormat: ImageFormat.PNG,
//        maxWidth: 256,
//        maxHeight: 256,
//        thumbnailPath: tempPath,
//        quality: 50,
//      );
//      return imageData;
    } catch (e) {
      print(e);
      eventBus.fire(showToast(CommonUtils.getLocale(null).noThumbnail));
      return null;
    }
  }

The log is

2020-04-20 18:14:36.340 26771-26924/com.mooncell.shangxian I/flutter: tempPath /storage/emulated/0
2020-04-20 18:14:36.341 26771-26924/com.mooncell.shangxian I/flutter: exists true

Try the thumbnailData first.

Apologize for my careless and waste of you time.I write it on my xml but forget to request permission dynamic cause i changed my device.Thanks for u reply.

I have a similar issue. I am trying to get a thumbnail from a video picked using the flutter_file_picker plugin and I am getting this issue.

`

<uses-permission android:name="android.permission.READ_EXTERNAL_STORAGE"/>

<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE"/>

<uses-permission android:name="android.permission.CAMERA" />

<uses-permission android:name="android.permission.RECORD_AUDIO" />

<uses-permission android:name="android.permission.FLASHLIGHT" />`

This is my AndroidManifest.xml permission part. and I am using this plugin in a similar way that @atheist1 used.

Looking for your response as quickly as possible as this is for production purposes.

Edit : This issue is only found in devices with Andoird 9 or below. and the flutter version that I am using is 1.20.0

I was constructing an invalid thumbnail path and was getting this error. Spend quite a bit of time as the impression from the error is a compile-time/binding issue. Will be good to throw a specific error when the thumbnail path is invalid or one does not have permission to the specified path.

[Stitch-Taotao]

I definitely certain the problem is that ,you through a wrong path ,you should pass a exit dir-Path to de thumbnailPath parameter

[kevin4dhd]

[justsoft]

Please check out the new 0.5.0 version. Thanks.
