Server Client Program

Overview

The server client program implements a Flutter Client and Python based server for remote file management. The target cases include creating, deleting, viewing and editing a file. Additionally the user can execute restricted remote commands at the server. The project makes use of Transmission Control Protocol (TCP) sockets for communication.

Server Side Script

Server actions avoid direct native system calls making the server platform independent. Flutter codebase, by default is developed with platform independency making the entire project platform independent

To start server run server.pyc.Alternatively, from /server_script/ execute the following:
python server.py
🚩 All server actions on directory ./reactor/
🔌 Default port is set to :65432.

Server Programming Interface:

Server Action	Command	Response
Request Path	`cd`	Absolute Server Path. (Time out of `500ms`)
Create File	`cf {filename}`	`1` indicating successful operation else `0`
View File	`vf {filename}`	`{file data} 1` if successful else `0`
Delete File	`df {filename}`	`1` indicating successful operation else `0`
Edit File	`cf {filename} {data}`	`1` indicating successful operation else `0`
Execute Command	`rc {command}`	Execute command on the server. `1` indicating successful operation else `0`
Log Out	`end`	Closes the active connection.
Shutdown Server	`shutdown`	Disconnect and shutdown the server.

Client Side Program

Client side leverages the functionalities of Flutter Framework and Dart combined. The TCP logic is purely built over dart or specifically using Socket class of dart:io library.
