Re: [pve-devel] [PATCH pve_flutter_frontend v1] chore: update `compileSdkVersion` to 35 and `targetSdkVersion` to 36

["Shan Shaji" <s.shaji@proxmox.com>]

Guys, I am sorry it's my mistake. The targetSdkVersion version 
should be <= compileSdkVersion [0] version. Since the biometric_storage 
plugin uses compileSdkVersion 35 i will update the 
targetSdkVersion to 35 and will create another patch.
