I try to wipe AVD data from android studio AVD manager, but it also gives the same error When i run flutter doctor, there is no any issues

Can anyone help me to fix this problem?

Answer 1

i have faced the same problem and the solution is to have a internet bandwidth of more than 1 MiB/s (make sure android studio is connected) and it downloads about 1 GB of data.

Answer 2

There is a similar issue on GitHub.

This error is due to network issue and not coming from Flutter, usually related to proxy config, self-signed certificates or some network problems (being blocked in China for example). You can try this solution here .
