Starting Flutter With Android Studio Problems

I want to run my hello world app on a device but when I run this app I catch errors in syncing . I don't know how to fix it. I had done every work for starting app like downloading

Solution 1:

your problem is gradle can't sync and download dependencies. if you live in Iran use proxy or vpn my suggestion is change your dns to "178.22.122.100" and "185.51.200.2" (shecan.ir)
