ssh

SSH and SFTP client for Flutter. Wraps iOS library NMSSH and Android library JSch.

Installation

Add ssh as a dependency in your pubspec.yaml file.

Usage

Create a client using password authentication

import 'package:ssh/ssh.dart';

var client = new SSHClient(
  host: "my.sshtest",
  port: 22,
  username: "sha",
  passwordOrKey: "Password01.",
);

Create a client using public key authentication

import 'package:ssh/ssh.dart';

var client = new SSHClient(
  host: "my.sshtest",
  port: 22,
  username: "sha",
  passwordOrKey: {
    "privateKey": """-----BEGIN RSA PRIVATE KEY-----
    ......
-----END RSA PRIVATE KEY-----""",
  },
);

Connect client

await client.connect();

Close client

await client.disconnect();

Execute SSH command

var result = await client.execute("ps");

Shell

Start shell:

  • Supported ptyType: vanilla, vt100, vt102, vt220, ansi, xterm
var result = await client.startShell(
  ptyType: "xterm", // defaults to vanilla
  callback: (dynamic res) {
    print(res);     // read from shell
  }
);

Write to shell:

await client.writeToShell("ls\n");

Close shell:

await client.closeShell();

SFTP

Connect SFTP:

await client.connectSFTP();

List directory:

var array = await client.sftpLs("/home"); // defaults to .

Create directory:

await client.sftpMkdir("testdir");

Rename file or directory:

await client.sftpRename(
  oldPath: "testfile",
  newPath: "newtestfile",
);

Remove directory:

await client.sftpRmdir("testdir");

Remove file:

await client.sftpRm("testfile");

Download file:

var filePath = await client.sftpDownload(
  path: "testfile",
  toPath: tempPath,
  callback: (progress) {
    print(progress); // read download progress
  },
);

// Cancel download:
await client.sftpCancelDownload();

Upload file:

await client.sftpUpload(
  path: filePath,
  toPath: ".",
  callback: (progress) {
    print(progress); // read upload progress
