Gio.File.prototype.create_async

    // Gjs wrapper for g_file_create_async()
}
  

Asynchronously creates a new file and returns an output stream for writing to it. The file must not already exist.

For more details, see Gio.File.prototype.create which is the synchronous version of this call.

When the operation is finished, callback will be called. You can then call Gio.File.prototype.create_finish to get the result of the operation.
