Upload file

Upload a file to the cloud using the following code snippet.

try {
  QBFile file = await QB.content.upload(url, public: public);
} on PlatformException catch (e) {
  
}

The maximum size of the uploaded file depends on the membership plan.

Get file info

Get information about a file by ID using the getInfo() method below. This method allows to load the file description model from the server, not the content of the file itself.

void getInfo() async {
  try {
    QBFile file = await QB.content.getInfo(fileId);
    int id = file.id;
  } on PlatformException catch (e) {
    
  }
}

Get file URL

There are two types of file URLs that can be obtained: private and public.

• Public URL allows anyone to access the file, no authorization token is needed.
• Private URL can be accessed only by QuickBlox user with a session token.

Get public URL

To receive a public URL, use the code snippet below.

try {
  String url = await QB.content.getPublicURL(fileUid);
} on PlatformException catch (e) {
  
}

Get private URL

To get a private URL of the uploaded file, use the following code snippet.

try {
  String url = await QB.content.getPrivateURL(fileUid);
} on PlatformException catch (e) {
  
}
