You need to do 2two things to show your device listing.
Go to your Android Studio, --> Filemenu → --> Project StructureFile → Project Structure and choose Projectthe project SDK from the options. I chose the latest one from the menu.
When you connect your real device to your PC/Laptoplaptop, make sure you choose
Transfer photos (PTP) mode
Transfer photos (PTP) mode.
NOTE: DON'T CHOOSE File transfer modeDon't choose File transfer mode. It will not work.
After doing the above 2two things, you can check the status of your device availability by writing flutter devices
on the command prompt.
I hope it shows your mobile device.
