I am working on one project which have list of short videos and i want to donwload in external storage. I am using following packages:
- video_player: ^2.6.1
- path_provider: ^2.0.15
- flutter_downloader: ^1.10.2
- permission_handler: ^10.2.0
- gallery_saver: ^2.3.2
Successfully video is downloaded in external storage and I am able to play video from notification(from download status). but after once i opened video i can not seen any where in external storage, unable to find downloaded video.
As a solution i tried gallery_saver package but it shows msg video file not found. Please anybody can solve this issue.
Following are my code:
Added code in Mainifest.xml
<uses-permission android:name="android.permission.INTERNET"/>
<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE"/>
<uses-permission android:name="android.permission.READ_EXTERNAL_STORAGE"/>
<provider
android:name="vn.hunghd.flutterdownloader.DownloadedFileProvider"
android:authorities="${applicationId}.flutter_downloader.provider"
android:exported="false"
android:grantUriPermissions="true">
<meta-data
android:name="android.support.FILE_PROVIDER_PATHS"
android:resource="@xml/provider_paths"/>
</provider>
