Upload and Retrieve the Temporary File - Flutter

This guide demonstrates how to upload and retrieve files from VideoSDK's temporary file storage system.

uploadBase64File()

• By using the uploadBase64File() method of the Room class, you can upload your file to Videosdk's Temporary storage.

• The uploadBase64File() method only works with base64. Therefore, it is necessary to convert your file into base64 format.

• You have to pass base64Data,token,fileName as parameter in uploadBase64File() function.

• The function will return the corresponding fileUrl, which you can then use to retrieve the file.

void uploadFile() async {
    String base64Data = "<Your File's base64>"; //Convert your file to base64 and pass here
    String token = "<VIDEOSDK_TOKEN>";
    String fileName = "myImage.jpeg"; // Provide name with extension here
    String url = await room.uploadBase64File(
        base64Data: base64Data,
        token : token,
        fileName : fileName,
    )
    print("fileUrl $url");
}

fetchBase64File()

• By using the fetchBase64File() method of the Room class, you can retrieve your file from Videosdk's Temporary storage.

• You have to pass the fileUrl which is returned by uploadBase64File() function, and the token as parameters to retrieve a file.

• This function will return the image in the form of base64.

void fetchFile() async {
    String url = "<Your FileUrl>" //Provide fileUrl which is returned by uploadBase64File()
    String token = "<VIDEOSDK_TOKEN>"
    String base64 = room.fetchBase64File( 
        token: token,
        url: url,
    )
    print("base64 $base64");
}

note

The file stored in the system will be automatically deleted once the current room/meeting comes to an end.
