updateFile method
Overwrite an existing file of fileID
with new data
Please use this command with caution, as this is equivalent to deleting the existing data in the file.
If you need to append data to the end of a file, use appendFile.
Implementation
Future<void> updateFile(String fileID, String data) => driveAPI.files.update(
File(),
fileID,
uploadMedia: Media(
Stream.value(ascii.encode(data)),
data.length,
),
);
