not working smoothly on windows. can't ping google.com and use ffmpeg. need help

[arieffajargemilang]

hello friends, I have a project which contains a windows terminal (CMD).

The following packages I use:
https://pub.dev/packages/flutter_pty
https://pub.dev/packages/xterm

However, there are several obstacles including:
1.⁠ ⁠can't ping google.com (gambar 1)

2.⁠ ⁠can't stream YouTube via ffmpeg (gambar 2)

out of curiosity I tried to clone the example project from the packages I was using
https://github.com/TerminalStudio/flutter_pty
without changing anything, but the result is the same (gambar 3)

anyone can help?
