How to run a systemd script at boot automatically using Linux

If you need to run a script at boot automatically using Linux with systemd this is the easiest solution.

• Create a script file calling your application

# vi /home/root/flutter-launcher.sh

#!/bin/sh

flutter-auto --b=/usr/share/flutter/gallery/3.3.10/release/ --f

• Modify the executable flag

# chmod +x /home/root/flutter-launcher.sh

• Create the service

# vi /etc/systemd/system/flutterstart.service

[Unit]
Description=Flutter starter

[Service]
ExecStart=/home/root/flutter-launcher.sh

[Install]
WantedBy=multi-user.target

Now, take a few more steps to enable and use the .service file:

• Start it

# sudo systemctl start flutterstart

• Enable it to run at boot

# sudo systemctl enable flutterstart

• Test it

# systemctl status flutterstart
